__TOC__

== Introduction ==

This page documents CAN bus signals and decoding investigations on the Lotus Exige V6 platform. The reference vehicle is a '''2021 Lotus Exige 390 Final Edition'''. Some signals may be shared with other Exige, Evora or Elise models, but such compatibility should not be assumed without testing.

The work uses a passive, '''listen-only''' CAN interface to collect standard 11-bit CAN frames from the high-speed vehicle bus. No control or diagnostic frames are intentionally transmitted. The purpose is to support data logging and an iPhone dashboard without altering the vehicle.

'''Last updated: 19 October 2026.'''

For discussion, evidence and contributions, see the [https://forums.seloc.org/viewthread.php?tid=510758 SELOC CAN Bus Mapping thread].

=== Evidence classifications ===

* '''Confirmed''' – Signal behaviour identified through tests on the reference car.
* '''Identified in firmware''' – Working application-level interpretation; exact underlying raw mapping not yet published here.
* '''Provisional''' – Candidate byte, scaling or interpretation requiring additional correlation.
* '''Reference''' – From an earlier third-party mapping, not yet independently validated on this car.
* '''Observed''' – Frame captured but meaning unknown.

Unless specified otherwise, all byte indexes are '''zero-based''' (B0 is the first byte); all identifiers and masks are hexadecimal.

The CAN reader is not an OBD-II PID scanner: it listens to native broadcast CAN messages. Generic OBD-II diagnostic requests and responses are a separate mechanism; see [[On board diagnostics]].

'''Safety:''' Do not add unnecessary bus termination.

== CAN identifier summary ==

{| class="wikitable sortable"
! CAN ID !! DLC !! Candidate or decoded function !! Status

|}

'''Driving mode:''' Normal, Sport and Race are identified and displayed correctly by the project firmware and iPhone app. The exact raw source CAN byte or state-machine definition is not yet documented on this page; do not equate the mode-button bit with a direct selected-mode byte.

== Detailed CAN mappings ==

=== 0x085 – Steering angle ===

'''DLC:''' 5

{| class="wikitable"
! Bytes !! Encoding !! Formula !! Status
|-
| B0–B1 || Signed 16-bit, little-endian || Steering angle (degrees) = raw × 0.09 || '''Confirmed'''
|-
| B2–B4 || Undetermined || – || Unknown
|}

=== 0x0A2 – Wheel/vehicle speed ===

'''DLC:''' 7. An earlier Exige V6 RaceCapturePRO mapping associates this identifier with wheel/vehicle speed. Byte-level decoding has not yet been confirmed on this reference vehicle.

'''Status: Reference.'''

=== 0x0A4 – Additional wheel speed ===

'''DLC:''' 8. Earlier RaceCapturePRO material identifies additional wheel-speed information here. Byte-level validation remains outstanding.

'''Status: Reference.'''

=== 0x0A8 – Candidate status ===

'''DLC:''' 3

{| class="wikitable"
! Byte !! Observations !! Interpretation !! Status
|-
| B1 || <code>0x01</code>, <code>0x09</code> || Possible vehicle or mode status; not conclusively decoded || Provisional
|}

Do not treat these raw values as an established Normal/Sport/Race mapping.

=== 0x102 – Unidentified frame ===

'''DLC:''' 3. Example at standstill: <code>00 00 9C</code>. '''Status: Observed.'''

=== 0x114 – Engine and driver inputs ===

'''DLC:''' 6

{| class="wikitable"
! Byte/bit !! Signal !! Decode !! Status
|-
| B0–B1 || Engine RPM || Older reference: 16-bit raw × 0.25; endian/order must be checked against captures || Reference / calibration tested
|-
| B3 || Throttle / accelerator || Percent = raw × 100 / 255 || '''Confirmed'''
|-
| B4 bits 4–5 (<code>0x30</code>) || Clutch input || See below || '''Confirmed'''
|-
| B4 bit 7 (<code>0x80</code>) || Drive-mode button activity || 0 = inactive; 1 = active || '''Confirmed'''
|-
| B5 bit 0 (<code>0x01</code>) || Brake pedal || 0 = released; 1 = pressed || '''Confirmed'''
|}

==== Clutch input ====

Apply mask <code>0x30</code> to B4:

{| class="wikitable"
! Masked value !! Observed state
|-
| <code>0x00</code> || Released
|-
| <code>0x10</code> || Intermediate
|-
| <code>0x20</code> || Deeper / fully pressed
|}

==== Drive-mode button versus selected mode ====

B4 bit 7 captures activity of the mode selector. It does '''not''' directly report the selected driving mode. See [[#Driving modes – Normal, Sport and Race|Driving modes]].

==== Engine RPM testing ====

Engine tests have included idle and approximate 2,000 and 3,000 RPM holds. A discrepancy between the dashboard and an initial iPhone display led to subsequent firmware corrections. Publish a final byte order and scaling only after checking the corrected output against recorded raw frames.

=== 0x0B7 – High-rate unidentified frame ===

'''DLC:''' 7. B3 and B6 change frequently. '''Status: Observed.'''

=== 0x303 – Vehicle dynamics ===

'''DLC:''' 7. A strong candidate for yaw-rate and lateral-acceleration data. B4 has been investigated for lateral acceleration, but signedness, offsets and scale factors are not yet validated.

'''Status: Provisional.'''

=== 0x400 – Vehicle status, coolant and fuel candidates ===

'''DLC:''' 7

Recorded example: <code>00 00 00 02 C4 81 18</code>

The following assignments were investigated during firmware development and are '''not yet a validated decoding of this entire frame''':

{| class="wikitable"
! Byte !! Candidate signal !! Proposed calculation !! Status
|-
| B4 || Fuel level || Percent = raw × 100 / 255 || Provisional; exact byte/source needs correlation
|-
| B6 || Coolant temperature || Degrees C = raw − 40 || Provisional; raw frame correlation required
|}

'''Consistency check:''' In the example frame B6 is hexadecimal <code>0x18</code> (decimal 24), giving −16°C under the proposed temperature formula. That is not a plausible warm-engine reading. Accordingly, the example does '''not''' validate this coolant mapping. Similarly, B4 is <code>0xC4</code> (decimal 196), not the separately observed fuel candidate raw value 137. Avoid combining measurements taken at different times into a single supposedly validated frame.

== Driving modes – Normal, Sport and Race ==

'''Status: Identified and working in firmware / iPhone application.'''

The three selected drive modes have been identified in project testing. The firmware distinguishes the states and passes the result to the iPhone display.

{| class="wikitable"
! Decoded state !! Displayed mode !! Project status
|-
| 0 || Normal || Identified
|-
| 1 || Sport || Identified
|-
| 2 || Race || Identified
|}

These values are '''decoded application states'''. They are not presented as raw values from a specific CAN byte until the underlying message, byte/bit and test captures are documented here.

'''Related known signal:''' <code>0x114</code>, B4 bit 7 (<code>0x80</code>) = drive-mode button input. This is separate from the selected-mode value.

== Coolant temperature – test record ==

Dashboard readings from one stationary warm-up/cool-down test:

{| class="wikitable sortable"
! Time !! Dashboard temperature !! Condition
|-
| 19:09 || 46°C || Engine running
|-
| 19:14 || 68°C || Engine running
|-
| 19:17 || 78°C || Engine running
|-
| 19:19 || 84°C || Engine running
|-
| 19:21 || 84°C || Engine stopped; ignition on
|-
| 19:39 || 68°C || Engine off; ignition switched off after observation
|}

The dashboard trace is a useful ground-truth comparison for raw CAN captures. A conventional <code>raw − 40</code> temperature decoding has been investigated. '''A definitive ID/byte assignment cannot be claimed solely from these dashboard observations.'''

== Fuel-level candidate ==

A provisional fuel-level calculation is:

<code>Fuel (%) = raw × 100 / 255</code>

For an observed raw value of 137, the calculated level is <code>53.7%</code>, broadly consistent with a dashboard gauge near half full. This is an initial plausibility check only, not proof of the byte assignment or a linear relationship over the entire tank range. Further measurements while refuelling and driving are needed.

== Calculated gear position ==

The Exige uses a manual gearbox. A gear estimate can be derived by comparing engine RPM with vehicle speed and matching the RPM/speed ratio against expected ratios for each gear. Neutral, clutch operation, low speed and wheel slip require special handling.

'''Status: Algorithm tested successfully with simulated inputs on the bench; in-car driving validation outstanding.'''

== iPhone display project ==

An ESP32-C3 sends decoded data over BLE to an iPhone application. The iPhone app was at '''version 1.1''' during this work; the ESP32 firmware has an independent version history.

* Confirm coolant-temperature CAN ID, byte and scaling against dashboard reference values.
* Confirm fuel-level source, scaling and tank-gauge behaviour.
* Validate wheel speeds and calculated gear while driving.
* Validate yaw rate and lateral acceleration, including scale and sign.
* Investigate exhaust-valve state and whether TPMS information is broadcast on the accessible bus.
* Check mappings on other Lotus models and model years.

== Contributing a new mapping ==

Please include the vehicle model/year, CAN ID, DLC, zero-based byte/bit, raw sample frame(s), interpretation, formula, units, capture/test conditions and whether the finding was independently confirmed. Avoid marking a value as confirmed based on a single static frame or a coincidental numerical match.

|}

Converting toe from mm to degrees:

# Measure the rim diameter in mm as the size e.g. 17" is not the actual diameter your measurements are based on.
# Multiply the result by PI to get the circumference.
# Divide the result by 360 to get mm per degree.
# Divide the toe mm by the mm/degree result to get toe in decimal degrees

Or Excel =DEGREES( ASIN( TOE_IN_MM / ( RIM_DIA_INCHES * 25.4 )))

Or use the calculator on this page, hypotenuse is the rim diameter the toe per wheel (total toe divided by 2) in mm is width (or toe in degrees is angle A). * http://joyfulcoder.net/sohcahtoa/

== Geo setting X does Y ==
Some starter guidelines although its really really complex stuff and dependent on many other factors;

* Increasing front camber from the default -0.1° to -0.5° each side will dramatically improve the understeer, although the inside edges of the tyres will wear slightly faster. Increasing past -1.0° is great for high speed corners but can compromise low speed cornering, will reduce braking effectiveness and it will tramline on the road.

* Increasing rear camber from the default -1.8° to -2.0° (or higher) makes the car more neutral after you've removed the under steer with front camber. Look at the ratios on the standard settings and maintain the front/rear % delta.

* Front toe affects stability or responsiveness of turn in. Front Toe out (standard) makes the car more responsive turn in but causes additional drag in straights. Front toe in is more stable in straight line.

* Rear Toe controls the stability of the rear through the corner. Rear toe in (standard) makes the car more stable and apparently the Elise toes in more at the rear as the suspension compresses. Rear toe out causes the rear to steer out from the corner, reducing stability.

== Factors affecting Geo ==
When asking questions on the forums about "the best geo for ..." the following need to be considered so make an effort to specify;

* What you are using the car for (road, sprint race, endurance race)
* Tyre spec (section & compound)
* Spring rates
* Damper spec and settings
* Ride height
* Current Geo settings
* Perceived problems with current setup

== Setting your own geo ==
Whilst a race prep specialist can charge £200 for a Geo you can DIY castor, camber and toe settings. With a lot of variability in quality at alignment centres (and Lotus dealers !) for the best results put the effort in yourself and build a string based alignment rig which can be more accurate than a computerised laser system. To make a DIY geo/alignment rig see:[[Geo Alignment Rig (Home Made)]]

1. The Hunter computerised laser alignment system is one of the best (the variability is quality of the operator) http://www.alignmycar.co.uk will find a local place with a Hunter alignment system who will provide a setup sheet showing castor, camber and toe (probably in dd:mm:ss rather than decimal degrees) for £15 and can set the front and rear toe for another £30.

2. If you are going to DIY you must have the relevant S1 or S2 service manual suspension sections. Setting castor and camber is straightforward as a caster washer and camber shim have fixed values, whereas toe is delicate - which way do you wind the flats and a quarter turn of the track rod can alter the toe by 2mm (e.g. just tightening the locknuts).

'''Absolutely critical to getting a good geo is having the right ballast in the seats e.g. for a 780Kg race Elise the difference between empty and an 85Kg driver is 5mm ride height, 0.2° camber and 1mm toe. (Depending on Spring rates used) Don't let your alignment place guess'''

Wheel Speed Sensor

2026-06-14T18:15:48Z

Happy.smiler: typo

= Replacing a Wheel Speed Sensor on a Lotus Exige 390 Final Edition (Also Applicable to Evora) =

== Symptoms ==
A failed wheel speed sensor will typically illuminate:

* ABS warning light (permanently on)
* Traction Control warning light (permanently on)

== Parts Required ==

* Replacement Bosch wheel speed sensor
** '''Bosch Part Number:''' ''(A132J6001F, Wheel Speed Sensor, rear suspension // BOSCH 0 986 594 610)''
* 8mm socket or spanner
* Jack and axle stands (or a lift)
* Lotus 20/20 Diagnostic Software and compatible interface, Link to guide, [[Lotus 20/20 diagnostic Software]]

== Diagnosis ==
Before replacing any parts, use the Lotus 20/20 diagnostic software to identify which wheel speed sensor has failed.

The software will report the specific sensor (front left, front right, rear left or rear right), avoiding unnecessary replacement or investigation.

One particularly useful feature is that if the sensor is unplugged, the software can distinguish between an open circuit and a connected but failed sensor, making diagnosis much easier.

== Confirming the Fault ==
If you want to be absolutely certain that the sensor itself has failed (rather than the wiring or ECU), a simple test is to swap it with the corresponding sensor on the opposite side of the car.

For example:

* Remove the suspected faulty front left sensor.
* Swap it with the working front right sensor.
* Reconnect both sensors and read the fault again using Lotus 20/20.

If the fault moves to the opposite side, the sensor itself is defective. If the fault remains on the original side, the problem is likely elsewhere, such as the wiring, connector or ABS module.

This quick test can save a lot of time chasing wiring faults and gives confidence that replacing the sensor will solve the problem.

== Replacement Procedure ==

# Park the car on level ground and safely jack up the affected corner.
# Remove the wheel.
# '''Recommended:''' Disconnect the vehicle battery before unplugging the sensor.
# Locate the wheel speed sensor on the hub assembly. The sensor is retained by a single '''7mm bolt''' and has a cable leading into the hub.
# Remove the 7mm retaining bolt.
# Carefully withdraw the old sensor from the hub.
# Fit the new Bosch sensor into position.
# Reinstall the 8mm retaining bolt and tighten securely.
# Reconnect the electrical connector.
# Reconnect the battery.
# Refit the wheel and lower the vehicle.

== Verification ==
Reconnect the Lotus 20/20 software and check for any stored fault codes.

In most cases the ABS and traction control warning lights should extinguish once the new sensor is recognised. If necessary, clear any stored fault codes and perform a short test drive to confirm normal operation.

== Notes ==

* This procedure is applicable to the '''Lotus Exige 390 Final Edition''' and is believed to be valid for '''Evora''' '''models''' using the same Bosch wheel speed sensor arrangement.
* Diagnosing the fault with Lotus 20/20 before replacing parts can save significant time. Without it, distinguishing between a failed sensor and damaged wiring can be difficult.
* In my case, unplugging the sensor was immediately detected by Lotus 20/20, demonstrating that the software can differentiate between a disconnected sensor and one that is electrically connected but faulty.
* Swapping the suspected faulty sensor with the equivalent sensor on the opposite side is an excellent way to prove whether the sensor itself has failed before ordering a replacement.

Wheel Speed Sensor

2026-06-13T17:04:07Z

Happy.smiler: 8mm bolt but 7mm

= Replacing a Wheel Speed Sensor on a Lotus Exige 390 Final Edition (Also Applicable to Evora) =

== Symptoms ==
A failed wheel speed sensor will typically illuminate:

* ABS warning light (permanently on)
* Traction Control warning light (permanently on)

== Parts Required ==

* Replacement Bosch wheel speed sensor
** '''Bosch Part Number:''' ''(A132J6001F, Wheel Speed Sensor, rear suspension // BOSCH 0 986 594 610)''
* 8mm socket or spanner
* Jack and axle stands (or a lift)
* Lotus 20/20 Diagnostic Software and compatible interface, Link to guide, [[Lotus 20/20 diagnostic Software]]

== Diagnosis ==
Before replacing any parts, use the Lotus 20/20 diagnostic software to identify which wheel speed sensor has failed.

The software will report the specific sensor (front left, front right, rear left or rear right), avoiding unnecessary replacement or investigation.

One particularly useful feature is that if the sensor is unplugged, the software can distinguish between an open circuit and a connected but failed sensor, making diagnosis much easier.

== Confirming the Fault ==
If you want to be absolutely certain that the sensor itself has failed (rather than the wiring or ECU), a simple test is to swap it with the corresponding sensor on the opposite side of the car.

For example:

* Remove the suspected faulty front left sensor.
* Swap it with the working front right sensor.
* Reconnect both sensors and read the fault again using Lotus 20/20.

If the fault moves to the opposite side, the sensor itself is defective. If the fault remains on the original side, the problem is likely elsewhere, such as the wiring, connector or ABS module.

This quick test can save a lot of time chasing wiring faults and gives confidence that replacing the sensor will solve the problem.

== Replacement Procedure ==

# Park the car on level ground and safely jack up the affected corner.
# Remove the wheel.
# '''Recommended:''' Disconnect the vehicle battery before unplugging the sensor.
# Locate the wheel speed sensor on the hub assembly. The sensor is retained by a single '''8mm bolt''' and has a cable leading into the hub.
# Remove the 7mm retaining bolt.
# Carefully withdraw the old sensor from the hub.
# Fit the new Bosch sensor into position.
# Reinstall the 8mm retaining bolt and tighten securely.
# Reconnect the electrical connector.
# Reconnect the battery.
# Refit the wheel and lower the vehicle.

== Verification ==
Reconnect the Lotus 20/20 software and check for any stored fault codes.

In most cases the ABS and traction control warning lights should extinguish once the new sensor is recognised. If necessary, clear any stored fault codes and perform a short test drive to confirm normal operation.

== Notes ==

* This procedure is applicable to the '''Lotus Exige 390 Final Edition''' and is believed to be valid for '''Evora''' '''models''' using the same Bosch wheel speed sensor arrangement.
* Diagnosing the fault with Lotus 20/20 before replacing parts can save significant time. Without it, distinguishing between a failed sensor and damaged wiring can be difficult.
* In my case, unplugging the sensor was immediately detected by Lotus 20/20, demonstrating that the software can differentiate between a disconnected sensor and one that is electrically connected but faulty.
* Swapping the suspected faulty sensor with the equivalent sensor on the opposite side is an excellent way to prove whether the sensor itself has failed before ordering a replacement.

If your ABS and traction control lights suddenly appear together, don't immediately assume the worst. A failed wheel speed sensor is a relatively simple and inexpensive fix once correctly diagnosed.

Wheel Speed Sensor

2026-06-12T10:41:02Z

Happy.smiler: If your post-2008 Lotus Elise or Exige suddenly displays both the ABS and traction control warning lights, there's a good chance that a wheel speed sensor has failed. Using Lotus 20/20 diagnostic software, you can quickly identify which sensor is at fault and even distinguish between a disconnected sensor and one that has internally failed.

Importing Lotus UK to Spain Post Brexit

2026-04-03T07:05:38Z

Happy.smiler: /* Observed behaviour */

== Importing a Lotus from the UK into Spain (Post-Brexit) ==

=== Overview ===

This guide describes the process of importing a Lotus vehicle from the UK into Spain after Brexit, based on a real case:

* Vehicle: Lotus Exige 390 Final Edition
* Registered Date: 04/2021
* Registration: Post-Brexit
* Total process time: ~5 months

'''Important:'''
This applies primarily to vehicles registered after 01/01/2021 (Brexit transition end).
Pre-Brexit vehicles typically follow a simpler process.

=== Key Authorities ===

* ITV (Inspección Técnica de Vehículos)
Spain’s official vehicle inspection and homologation body (similar to UK MOT + approval for registration)

* Spanish Ministry of Industry
Responsible for homologation framework and recognition of authorised signatories

=== Step 1 – Certificate of Conformity (CoC) ===

==== Expected ====
* Manufacturer-issued CoC

==== How to get a CoC ====
The recommended first step to obtain a Certificate of Conformity (CoC) for a Lotus is to contact your local Lotus dealer and ask them to request and supply the document on your behalf. In many cases, dealers can access the manufacturer systems directly and may simplify the process. If this route is not successful, you can then contact Lotus Customer Care directly, typically via email or by phone through their UK headquarters, with requests often handled. You will need to provide your vehicle’s VIN (Vehicle Identification Number), proof of ownership such as the V5C or purchase invoice, and your contact details, and sometimes identification. The CoC usually costs between €150 and €200 and is delivered within one to three weeks, depending on the vehicle and availability of records. It is typically issued as a PDF and signed by Lotus. However, for vehicles registered after 01/01/2021 (post-Brexit), the CoC alone may not be sufficient for registration in Spain, and it is advisable to request additional documentation at the same time, such as a homologation codes letter, technical conformity letter, type approval confirmation, and signatory authorisation. Keeping all correspondence is important, as it may be required by ITV during the registration process.

==== Reality (Post-Brexit) ====
* CoC may NOT be sufficient
* Additional documentation often required, especially for:
** Post-Brexit vehicles
** Small series homologation vehicles

=== Step 2 – Homologation Number (Critical) ===

==== Example format ====
E4*KS07/__*____*__

==== Breakdown ====

* E4 → Approval authority (Netherlands)
* KS → Kleine Serie (Small Series approval)
* Remaining digits → Directive / variant / version

==== Where to Find Homologation Numbers ====

For a Lotus vehicle (and most EU-approved vehicles), the homologation number (type approval number) can be found in several locations.

===== 1. Certificate of Conformity (CoC) =====

Primary source.

The homologation number is always listed on the CoC.

Look for fields such as:
* "Type approval number"
* "EC type-approval number"

Example format:
e4*KS07/__*____*__

This is the most reliable and official reference.

===== 2. Vehicle Identification Plate (VIN Plate) =====

The homologation number may also appear on the manufacturer’s plate on the vehicle.

Typical locations:
* Front compartment (Elise/Exige) on Door sill

===== 3. Registration Documents =====

In some cases, the homologation number may appear on registration paperwork:

* UK V5C (Logbook)

===== Summary =====

The homologation number is most reliably found on the Certificate of Conformity (CoC), but it also appears on the vehicle plate.

=== Step 3 – Homologation Codes Document ===

==== Requirement ====

A manufacturer-issued document listing homologation codes, Lotus calls this document "DOCUMENT CERTIFYING COMPLIANCE WITH REGULATED ACTS FOR VEHICLES FOR PRE-REGISTRATION INSPECTIONS"

==== Format ====

* Typically 1–2 pages (example: in my case 2 pages)

==== Content ====

* EU regulatory references
* System-level approvals:
** Lighting
** Emissions
** Braking
** Noise
** Safety systems
* Cross-reference to type approval framework

==== Purpose ====

Provides detailed technical compliance evidence beyond the CoC

==== ITV Feedback ====

* Content: Accepted
* Issue: Signature validation (see below)

=== Step 4 – Authorised Signatory Issue ===

==== Requirement ====

ITV may require confirmation that the signatory is: ''Recognised by the Spanish Ministry of Industry''

==== Problem ====

* No public register exists
* Manufacturers (including Lotus) do NOT maintain Spain-specific lists
* Even when:
** Documents are correct
** Authority is confirmed

→ ITV may still reject based on signature

=== Step 5 – Ministry of Industry Escalation ===

==== Observed behaviour ====

* Regional ITV offices escalate, to regional offices and then to Madrid
* Focus on:
** Traceability of signatory
** Recognition in Spanish system

==== Outcome ====

* No clear standard process
* Interpretation varies

=== Taxation (Post-Brexit Imports) ===

For vehicles imported from the UK into the EU:

* 21% VAT (IVA in Spain)
* ~10% import duty

'''Important:'''
These taxes generally apply to any UK → EU vehicle import post-Brexit (subject to origin rules).

=== Manufacturer Support (Lotus) ===

Support from Lotus was critical:
* Responsive Customer Care
* Provided all required documentation
* Confirmed signatory authority
* English-speaking support
* Helpful and approachable ("simpáticos")

=== Contacting Lotus Customer Care ===

==== Contact Details ====

* Email: ukcustomercare@eu.lotuscars.com
* Telephone (UK): +44 (0) 3300948047

==== Customer Escalations Team ====
* Email: escalations@eu.lotuscars.com

==== Notes ====

* Expect follow-ups, they return calls, without their help it wouldn't have been possible.

=== Key Learnings ===

* CoC alone may not be sufficient
* KS (Small Series) homologation is valid but not widely understood
* Expect detailed technical documentation requests
* Signature validation can block progress
* Process varies between ITV stations
* Time required: ~5 months

=== Recommendation ===

Would this process be recommended?

'''No'''

Due to:

* Administrative complexity
* Lack of clarity
* Time required
* Tax burden (21% + 10%)

=== Summary ===

Importing a post-Brexit UK Lotus into Spain is feasible but complex, especially for:

* Small series vehicles
* Non-standard homologation formats

Expect a documentation-heavy process with possible escalation to authorities.

* Year: 2021
* Registration: Post-Brexit
* Total process time: ~5 months

'''Important:'''
This applies primarily to vehicles registered after 01/01/2021 (Brexit transition end).
Pre-Brexit vehicles typically follow a simpler process.

=== Key Authorities ===

* ITV (Inspección Técnica de Vehículos)
Spain’s official vehicle inspection and homologation body (similar to UK MOT + approval for registration)

* Spanish Ministry of Industry
Responsible for homologation framework and recognition of authorised signatories

=== Step 1 – Certificate of Conformity (CoC) ===

==== Expected ====
* Manufacturer-issued CoC

==== How to get a CoC ====
The recommended first step to obtain a Certificate of Conformity (CoC) for a Lotus is to contact your local Lotus dealer and ask them to request and supply the document on your behalf. In many cases, dealers can access the manufacturer systems directly and may simplify the process. If this route is not successful, you can then contact Lotus Customer Care directly, typically via email or by phone through their UK headquarters, with requests often handled. You will need to provide your vehicle’s VIN (Vehicle Identification Number), proof of ownership such as the V5C or purchase invoice, and your contact details, and sometimes identification. The CoC usually costs between €150 and €200 and is delivered within one to three weeks, depending on the vehicle and availability of records. It is typically issued as a PDF and signed by Lotus. However, for vehicles registered after 01/01/2021 (post-Brexit), the CoC alone may not be sufficient for registration in Spain, and it is advisable to request additional documentation at the same time, such as a homologation codes letter, technical conformity letter, type approval confirmation, and signatory authorisation. Keeping all correspondence is important, as it may be required by ITV during the registration process.

==== Reality (Post-Brexit) ====
* CoC may NOT be sufficient
* Additional documentation often required, especially for:
** Post-Brexit vehicles
** Small series homologation vehicles

=== Step 2 – Homologation Number (Critical) ===

==== Example format ====
E4*KS07/__*____*__

==== Breakdown ====

* E4 → Approval authority (Netherlands)
* KS → Kleine Serie (Small Series approval)
* Remaining digits → Directive / variant / version

==== Where to Find Homologation Numbers ====

For a Lotus vehicle (and most EU-approved vehicles), the homologation number (type approval number) can be found in several locations.

===== 1. Certificate of Conformity (CoC) =====

Primary source.

The homologation number is always listed on the CoC.

Look for fields such as:
* "Type approval number"
* "EC type-approval number"

Example format:
e4*KS07/__*____*__

This is the most reliable and official reference.

===== 2. Vehicle Identification Plate (VIN Plate) =====

The homologation number may also appear on the manufacturer’s plate on the vehicle.

Typical locations:
* Front compartment (Elise/Exige) on Door sill

===== 3. Registration Documents =====

In some cases, the homologation number may appear on registration paperwork:

* UK V5C (Logbook)

===== Summary =====

The homologation number is most reliably found on the Certificate of Conformity (CoC), but it also appears on the vehicle plate.

=== Step 3 – Homologation Codes Document ===

==== Requirement ====

A manufacturer-issued document listing homologation codes, Lotus calls this document "DOCUMENT CERTIFYING COMPLIANCE WITH REGULATED ACTS FOR VEHICLES FOR PRE-REGISTRATION INSPECTIONS"

==== Format ====

* Typically 1–2 pages (example: in my case 2 pages)

==== Content ====

* EU regulatory references
* System-level approvals:
** Lighting
** Emissions
** Braking
** Noise
** Safety systems
* Cross-reference to type approval framework

==== Purpose ====

Provides detailed technical compliance evidence beyond the CoC

==== ITV Feedback ====

* Content: Accepted
* Issue: Signature validation (see below)

=== Step 4 – Authorised Signatory Issue ===

==== Requirement ====

ITV may require confirmation that the signatory is: ''Recognised by the Spanish Ministry of Industry''

==== Problem ====

* No public register exists
* Manufacturers (including Lotus) do NOT maintain Spain-specific lists
* Even when:
** Documents are correct
** Authority is confirmed

→ ITV may still reject based on signature

=== Step 5 – Ministry of Industry Escalation ===

==== Observed behaviour ====

* Regional ITV offices escalate to Madrid
* Focus on:
** Traceability of signatory
** Recognition in Spanish system

==== Outcome ====

* No clear standard process
* Interpretation varies

=== Taxation (Post-Brexit Imports) ===

For vehicles imported from the UK into the EU:

* 21% VAT (IVA in Spain)
* ~10% import duty

'''Important:'''
These taxes generally apply to any UK → EU vehicle import post-Brexit (subject to origin rules).

=== Manufacturer Support (Lotus) ===

Support from Lotus was critical:
* Responsive Customer Care
* Provided all required documentation
* Confirmed signatory authority

Call centre based in Barcelona:
* English-speaking support
* Helpful and approachable ("simpáticos")

=== Contacting Lotus Customer Care ===

==== Contact Details ====

* Email: ukcustomercare@eu.lotuscars.com
* Telephone (UK): +44 (0) 3300948047

==== Customer Escalations Team ====
* Email: escalations@eu.lotuscars.com

==== Notes ====

* Expect follow-ups, they return calls, without their help it wouldn't have been possible.

=== Key Learnings ===

* CoC alone may not be sufficient
* KS (Small Series) homologation is valid but not widely understood
* Expect detailed technical documentation requests
* Signature validation can block progress
* Process varies between ITV stations
* Time required: ~5 months

=== Recommendation ===

Would this process be recommended?

'''No'''

Due to:

* Administrative complexity
* Lack of clarity
* Time required
* Tax burden (21% + 10%)

=== Summary ===

Importing a post-Brexit UK Lotus into Spain is feasible but complex, especially for:

* Small series vehicles
* Non-standard homologation formats

Expect a documentation-heavy process with possible escalation to authorities.

Importing Lotus UK to Spain Post Brexit

2026-03-31T21:41:24Z

Happy.smiler: Importing a Lotus from the UK into Spain after Brexit (for vehicles registered from 01/01/2021 onwards) is a documentation-heavy and often non-standard process that can take several months to complete. While the Certificate of Conformity (CoC) is the starting point, it is typically not sufficient on its own, and additional documents such as homologation codes, technical conformity letters, and type approval confirmation are often required.

Tyre pressures

2026-03-29T13:50:46Z

Happy.smiler: /* Tyre pressures */

===Tyre pressures===

Make sure you buy a tyre pressure gauge of your own, who knows when the last time the air pump at the garage was calibrated.

Buying your own gauge will insure you get similar readings.

'''Please enter all readings as COLD for Road and HOT for Track'''

Please beware that tyre pressure is part of your suspension setup and the pressure numbers from the manual is a good start if you run factory geo and OE tyres. Anything else is trial and error.

That said starting at the low end will help you find the correct pressure faster.

===Toyo 888 Tyre Pressures===

Extracted from the following thread:

http://forums.seloc.org/t/222602

My name is Alan Meaker, I am the Motorsport Manager for Toyo Tyres (UK) Ltd.

I was at Rockingham on the Saturday 1ST March at the LOT trackday and worked with a couple of cars using our R888 tyre regarding pressures and tread temperatures.

What I would like to do is to offer some advice on tyre temperatures and pressures and how to achieve the best from our tyres when taking part in either trackdays or racing.

The R888 has a semi race construction (very stiff) and a race tread compound. The optimum tread temperature range is between 85C and 95C measured using a probe type pyrometer, and ideally a maximum difference across the tread of 9C. The maximum hot pressure we recommend is 40psi. Camber angles up to 5 degrees are permissible but the final setting will depend on tread temperatures. It is advisable to have as much positive castor as practical as castor induces a beneficial camber change during cornering. I recommend that the tyres be put through 2 heat cycles before hard use.

The pressures you use will initially depend on the weight of the car, too little pressure on a heavy car can lead to over deflection of the tyre and subsequent failure.

Below are some basic settings:

{|style="text-align: center;"
!VEHICLE WEIGHT!!COLD PRESSURE!!HOT PRESSURE
|-
|Very Light < 800kg||17 - 22 psi||22 - 29 psi
|-
|Light 800kg - 1000kg||20 - 26 psi||24 - 32 psi
|-
|Heavy 1000kg - 1400kg||23 - 27 psi||28 - 40 psi
|-
|Very Heavy > 1400kg||27 - 35 psi||37 - 40 psi
|}

As a tyre gets hotter the pressure increases, this is due to the moisture in the air. The cold pressure you set to achieve a desired hot pressure will depend on the conditions on the day i.e. ambient and track temperature, wet or dry. If the day/track is cold you will need to start with a higher cold pressure as the tyre will not get as hot therefore the pressure increase will not be so great.
Hot pressures must be balanced side to side. Once the tyres have cooled you will find that you will have a difference in pressure side to side, if you have been racing on a right hand track you will find the offside pressures will usually be higher than the nearside.

Changing hot inflation pressures by small amounts can be used to fine tune handling.

Reduce Oversteer Reduce rear pressures or increase front pressures
Increase Oversteer Increase rear pressures or reduce front pressures
Reduce Understeer Reduce front pressures or increase rear pressures
Increase Understeer Increase front pressures or reduce rear pressures

Achieving the required tread temperatures will depend again on the conditions on the day i.e. ambient and track temperature, wet or dry.

You often here competitors saying “My tyres started to go of towards the end of the race”, this is usually due to the tread getting to hot.

The tread temperatures are constantly changing through out a race, hotter when cornering and cooler when on the straights and cooling even more when you are slowing to come into the pits. Therefore the temps you record in the pits will be lower than those during the race. So if you record temperatures within the range given above the probability is the temps will be too high during the race.

Increasing your tyre pressures will cause your tread temperatures to increase, more pressure stiffens the tyre’s casing which results in the tread having to do more work resulting in the tread getting hotter. Lowering your pressures will cause them to decrease.

Inevitably changing one thing will affect other things, the whole set up of your car is a compromise between anything that is adjustable.

Some of you are also asking about different compounds. Originally we only had one compound ‘GG’ (medium hard), but we have now introduced some sizes in a ‘SG’ (soft/wet) compound. This was done primarily for sprint/hillclimb (around 60 second runs) where the distances covered are relatively short and you need the tyres to work/heat up very quickly. This is not a compound I would recommend for race/trackday dry use as the tyres will go off very quickly.

The sizes that will be available are:

185/60R13, 205/60R13, 195/50R15, 205/50R15, 225/45R16, 225/45R17.

Another subject is the introduction of our Proxes R1R. This tyre was due to be launched at the beginning of 2008, unfortunately this has been delayed to at least mid 2008 but there is a good chance it will be latter than this. Regarding sizes, initially we will have a rear fit (225/45ZR17) but not the front (195/50R16).

I hope this is of some use to you.

If I can be of any further assistance please give me a call.

Alan

On board diagnostics

2025-11-28T16:52:21Z

Happy.smiler:

[[Image:Odb2 plug.jpg|thumb|left|OBD2 connector (plug)]]
Like all cars, the Elise is fitted with an '''On board diagnostic''', or '''OBD''', connector (socket) tucked away in the passenger foot well.

This can be used to communicate with the cars [[ECU]] for retrieving diagnostic information, resetting the [[MIL]] or viewing live engine parameters.

NOTE: This is only valid for the Elise S2/Exige S2. The Elise S1 and Exige S1 is equipped with a similar connector, but this connector is NOT OBD compatible!
{{clr}}

The standard is also referred as: -
*OBD2
*OBD-2
*OBDII
*OBD-II

In europe the standard is called: -
*E-OBD
*EOBD

In practice it's very close to the USA-based OBD2 (J2534) standard and most OBD2 scanners will work. The meaning of some of the codes in EOBD are slightly different from OBD2 though.

==Port Location==

===Evora===

<s>On a cable that hangs down</s> under the dash on the drivers side or (passenger side on left hand drive cars).

Fixed to the aluminium crossmember, pointing down, just past the point where the dash leather stops in the footwell, you should be able to feel it without stretching forward too much from the driving position.

[[image:2010-Lotus-Evora-Interior.jpg]]

==DIY==
[[Image:OBDII_111R.jpg|thumb|left|OBDII Connector, S2 111R]]
[[Image:OBDII.jpg|thumb|left|OBDII Connector, S2 Exige]]
{{clr}}
On the S2 Elise it is quite simple to connect to the cars [[ECU]] yourself.

Until 2008 all S2's can be queried using the ISO 9141-2 OBD II protocol for the OBD required error codes and results.
From 2008 onwards CAN is the only permitted OBD2 protocol.

All S2 variants also have a CAN bus connection on the same diagnostic connector.

For the Rover powered S2 variants the CAN bus is only connected to the engine ECU and used by the Lotus scan tool to reflash/upgrade the ECU and obtain the ECU dump information at the first service.

The dash unit still uses discrete inputs for the various gauges and information readouts, either connecting directly to sensors or using PWM signals from the ECU.

The Toyota powered S2 (111R, Fed-Elise, Exige2) also connects the CAN bus (running at 1 megabit/s) to the dash unit and does away with most of the discrete inputs to the dash unit, RPM, speed, MIL/CEL, coolant temperature and fuel level are supplied via the CAN Bus, the rest are discreete inputs.

The ScanTool3 provides the ECU reflash and DUMP via the K line, using the L line as an enable latch, the CAN bus is not used for reflashing or ECU dump, though it can be used by Lotus with their internal EFi supplied mapping tools.

Lotus has a tool called Lotus 20/20. What Lotus 20/20 can do...

Read general vehicle data** — It displays ECU (engine-control unit) information: part numbers, emissions-related data, VIN, and other core vehicle metadata.
Read and clear diagnostic trouble codes (DTCs)** — You can scan all vehicle systems (engine, transmission / TCU, ABS, SRS/airbag on many models) for fault codes, and clear them.
Flash / program certain control units** — For supported cars (most 2007+ Lotus, with exceptions), you can re-flash or update firmware/software for at least the Engine Management System (EMS), Transmission Control Unit (TCU), and ABS.
Adjust some configuration via instrument pack (on supported cars)

Limitations / What it doesn’t reliably do (or may depend on model/access level)

* The version available to consumers/enthusiasts (“Independent Retailers” licence) is **limited** compared to the full dealer version.
* It apparently **does not support live data streaming** (e.g. reading live sensor data like transmission temperature for maintenance)
* Some modules (for example SRS/airbag) may use different communications protocols (e.g. K-Line rather than CAN), which could make them harder to access depending on adapter and vehicle model.

What you need to run 20/20

* A Windows-based laptop + a **J2534 pass-through adapter** to connect to the car’s OBD-port
* A valid Lotus-issued licence/subscription key — software won’t run without it.

🧰 Typical Use Cases

* Clearing fault codes after maintenance or repairs.
* Flashing updated firmware/software for EMS, TCU or ABS (e.g. after parts replacement).
* Checking VIN, part numbers, emissions data — useful for verifying the vehicle’s configuration.
* Adjusting some vehicle configuration bits.

==OBD-II codes==
OBD-II codes consist of a number of parts. Here is a sample OBD2 code:

P0171

Here is a breakdown of what each digit of the code means:

'''First Character - System'''
The first character identifies identifies the system related to the trouble code.

P = Powertrain

B = Body

C = Chassis

U = Undefined

'''Second Digit - Code Type'''
The second digit identifies whether the code is a generic code (same on all OBD-II equpped vehicles), or a manufacturer specific code.

0 = Generic (this is the digit zero -- not the letter "O")

1 = Enhanced (manufacturer specific)

'''Third Digit - Sub-System'''
The third digit denotes the type of sub-system that pertains to the code

1 = Emission Management (Fuel or Air)

2 = Injector Circuit (Fuel or Air)

3 = Ignition or Misfire

4 = Emission Control

5 = Vehicle Speed & Idle Control

6 = Computer & Output Circuit

7 = Transmission

8 = Transmission

9 = SAE Reserved

0 = SAE Reserved

'''Fourth and Fifth Digits'''
These digits, along with the others, are variable, and relate to a particular problem. For example,a P0171 code means P0171 - System Too Lean (Bank 1).

On board diagnostics

2025-11-28T15:24:50Z

Happy.smiler:

[[Image:Odb2 plug.jpg|thumb|left|OBD2 connector (plug)]]
Like all cars, the Elise is fitted with an '''On board diagnostic''', or '''OBD''', connector (socket) tucked away in the passenger foot well.

This can be used to communicate with the cars [[ECU]] for retrieving diagnostic information, resetting the [[MIL]] or viewing live engine parameters.

NOTE: This is only valid for the Elise S2/Exige S2. The Elise S1 and Exige S1 is equipped with a similar connector, but this connector is NOT OBD compatible!
{{clr}}

The standard is also referred as: -
*OBD2
*OBD-2
*OBDII
*OBD-II

In europe the standard is called: -
*E-OBD
*EOBD

In practice it's very close to the USA-based OBD2 (J2534) standard and most OBD2 scanners will work. The meaning of some of the codes in EOBD are slightly different from OBD2 though.

==Port Location==

===Evora===

<s>On a cable that hangs down</s> under the dash on the drivers side or (passenger side on left hand drive cars).

Fixed to the aluminium crossmember, pointing down, just past the point where the dash leather stops in the footwell, you should be able to feel it without stretching forward too much from the driving position.

[[image:2010-Lotus-Evora-Interior.jpg]]

==DIY==
[[Image:OBDII_111R.jpg|thumb|left|OBDII Connector, S2 111R]]
[[Image:OBDII.jpg|thumb|left|OBDII Connector, S2 Exige]]
{{clr}}
On the S2 Elise it is quite simple to connect to the cars [[ECU]] yourself.

Until 2008 all S2's can be queried using the ISO 9141-2 OBD II protocol for the OBD required error codes and results.
From 2008 onwards CAN is the only permitted OBD2 protocol.

All S2 variants also have a CAN bus connection on the same diagnostic connector.

For the Rover powered S2 variants the CAN bus is only connected to the engine ECU and used by the Lotus scan tool to reflash/upgrade the ECU and obtain the ECU dump information at the first service.

The dash unit still uses discrete inputs for the various gauges and information readouts, either connecting directly to sensors or using PWM signals from the ECU.

The Toyota powered S2 (111R, Fed-Elise, Exige2) also connects the CAN bus (running at 1 megabit/s) to the dash unit and does away with most of the discrete inputs to the dash unit, RPM, speed, MIL/CEL, coolant temperature and fuel level are supplied via the CAN Bus, the rest are discreete inputs.

The ScanTool3 provides the ECU reflash and DUMP via the K line, using the L line as an enable latch, the CAN bus is not used for reflashing or ECU dump, though it can be used by Lotus with their internal EFi supplied mapping tools.

Lotus has a tool called Lotus 20/20. What Lotus 20/20 can do...

Read general vehicle data** — It displays ECU (engine-control unit) information: part numbers, emissions-related data, VIN, and other core vehicle metadata.
Read and clear diagnostic trouble codes (DTCs)** — You can scan all vehicle systems (engine, transmission / TCU, ABS, SRS/airbag on many models) for fault codes, and clear them.
Flash / program certain control units** — For supported cars (most 2007+ Lotus, with exceptions), you can re-flash or update firmware/software for at least the Engine Management System (EMS), Transmission Control Unit (TCU), and ABS.
Adjust some configuration via instrument pack (on supported cars)

Limitations / What it doesn’t reliably do (or may depend on model/access level)

* The version available to consumers/enthusiasts (“Independent Retailers” licence) is **limited** compared to the full dealer version.
* It apparently **does not support live data streaming** (e.g. reading live sensor data like transmission temperature for maintenance)
* Some modules (for example SRS/airbag) may use different communications protocols (e.g. K-Line rather than CAN), which could make them harder to access depending on adapter and vehicle model.

What you need to run 20/20

* A Windows-based laptop + a **J2534 pass-through adapter** to connect to the car’s OBD-port
* A valid Lotus-issued licence/subscription key — software won’t run without it.

🧰 Typical Use Cases

* Clearing fault codes after maintenance or repairs.
* Flashing updated firmware/software for EMS, TCU or ABS (e.g. after parts replacement).
* Checking VIN, part numbers, emissions data — useful for verifying the vehicle’s configuration.
* Adjusting some vehicle configuration bits.

==OBD-II codes==
OBD-II codes consist of a number of parts. Here is a sample OBD2 code:

P0171

Here is a breakdown of what each digit of the code means:

'''First Character - System'''
The first character identifies identifies the system related to the trouble code.

P = Powertrain

B = Body

C = Chassis

U = Undefined

'''Second Digit - Code Type'''
The second digit identifies whether the code is a generic code (same on all OBD-II equpped vehicles), or a manufacturer specific code.

0 = Generic (this is the digit zero -- not the letter "O")

1 = Enhanced (manufacturer specific)

'''Third Digit - Sub-System'''
The third digit denotes the type of sub-system that pertains to the code

1 = Emission Management (Fuel or Air)

2 = Injector Circuit (Fuel or Air)

3 = Ignition or Misfire

4 = Emission Control

5 = Vehicle Speed & Idle Control

6 = Computer & Output Circuit

7 = Transmission

8 = Transmission

9 = SAE Reserved

0 = SAE Reserved

'''Fourth and Fifth Digits'''
These digits, along with the others, are variable, and relate to a particular problem. For example,a P0171 code means P0171 - System Too Lean (Bank 1).

Tyre pressures

2025-08-25T14:28:11Z

Happy.smiler: /* Tyre pressures */

===Tyre pressures===

Make sure you buy a tyre pressure gauge of your own, who knows when the last time the air pump at the garage was calibrated.

Buying your own gauge will insure you get similar readings.

'''Please enter all readings as COLD for Road and HOT for Track'''

Please beware that tyre pressure is part of your suspension setup and the pressure numbers from the manual is a good start if you run factory geo and OE tyres. Anything else is trial and error.

That said starting at the low end will help you find the correct pressure faster.

===Toyo 888 Tyre Pressures===

Extracted from the following thread:

http://forums.seloc.org/t/222602

My name is Alan Meaker, I am the Motorsport Manager for Toyo Tyres (UK) Ltd.

I was at Rockingham on the Saturday 1ST March at the LOT trackday and worked with a couple of cars using our R888 tyre regarding pressures and tread temperatures.

What I would like to do is to offer some advice on tyre temperatures and pressures and how to achieve the best from our tyres when taking part in either trackdays or racing.

The R888 has a semi race construction (very stiff) and a race tread compound. The optimum tread temperature range is between 85C and 95C measured using a probe type pyrometer, and ideally a maximum difference across the tread of 9C. The maximum hot pressure we recommend is 40psi. Camber angles up to 5 degrees are permissible but the final setting will depend on tread temperatures. It is advisable to have as much positive castor as practical as castor induces a beneficial camber change during cornering. I recommend that the tyres be put through 2 heat cycles before hard use.

The pressures you use will initially depend on the weight of the car, too little pressure on a heavy car can lead to over deflection of the tyre and subsequent failure.

Below are some basic settings:

{|style="text-align: center;"
!VEHICLE WEIGHT!!COLD PRESSURE!!HOT PRESSURE
|-
|Very Light < 800kg||17 - 22 psi||22 - 29 psi
|-
|Light 800kg - 1000kg||20 - 26 psi||24 - 32 psi
|-
|Heavy 1000kg - 1400kg||23 - 27 psi||28 - 40 psi
|-
|Very Heavy > 1400kg||27 - 35 psi||37 - 40 psi
|}

As a tyre gets hotter the pressure increases, this is due to the moisture in the air. The cold pressure you set to achieve a desired hot pressure will depend on the conditions on the day i.e. ambient and track temperature, wet or dry. If the day/track is cold you will need to start with a higher cold pressure as the tyre will not get as hot therefore the pressure increase will not be so great.
Hot pressures must be balanced side to side. Once the tyres have cooled you will find that you will have a difference in pressure side to side, if you have been racing on a right hand track you will find the offside pressures will usually be higher than the nearside.

Changing hot inflation pressures by small amounts can be used to fine tune handling.

Reduce Oversteer Reduce rear pressures or increase front pressures
Increase Oversteer Increase rear pressures or reduce front pressures
Reduce Understeer Reduce front pressures or increase rear pressures
Increase Understeer Increase front pressures or reduce rear pressures

Achieving the required tread temperatures will depend again on the conditions on the day i.e. ambient and track temperature, wet or dry.

You often here competitors saying “My tyres started to go of towards the end of the race”, this is usually due to the tread getting to hot.

The tread temperatures are constantly changing through out a race, hotter when cornering and cooler when on the straights and cooling even more when you are slowing to come into the pits. Therefore the temps you record in the pits will be lower than those during the race. So if you record temperatures within the range given above the probability is the temps will be too high during the race.

Increasing your tyre pressures will cause your tread temperatures to increase, more pressure stiffens the tyre’s casing which results in the tread having to do more work resulting in the tread getting hotter. Lowering your pressures will cause them to decrease.

Inevitably changing one thing will affect other things, the whole set up of your car is a compromise between anything that is adjustable.

Some of you are also asking about different compounds. Originally we only had one compound ‘GG’ (medium hard), but we have now introduced some sizes in a ‘SG’ (soft/wet) compound. This was done primarily for sprint/hillclimb (around 60 second runs) where the distances covered are relatively short and you need the tyres to work/heat up very quickly. This is not a compound I would recommend for race/trackday dry use as the tyres will go off very quickly.

The sizes that will be available are:

185/60R13, 205/60R13, 195/50R15, 205/50R15, 225/45R16, 225/45R17.

Another subject is the introduction of our Proxes R1R. This tyre was due to be launched at the beginning of 2008, unfortunately this has been delayed to at least mid 2008 but there is a good chance it will be latter than this. Regarding sizes, initially we will have a rear fit (225/45ZR17) but not the front (195/50R16).

I hope this is of some use to you.

If I can be of any further assistance please give me a call.

===Tyre pressures===

Make sure you buy a tyre pressure gauge of your own, who knows when the last time the air pump at the garage was calibrated.

Buying your own gauge will insure you get similar readings.

'''Please enter all readings as COLD for Road and HOT for Track'''

Please beware that tyre pressure is part of your suspension setup and the pressure numbers from the manual is a good start if you run factory geo and OE tyres. Anything else is trial and error.

That said starting at the low end will help you find the correct pressure faster.

Happy.smiler:

The system is charged with '''0.55 kg''' of refrigerant HFC R134a.

Filling points on Elise are located in the front services compartment, and on the Exige ahead of the RH rear wheel, accessible after removal of the front most part of the wheel-arch liner. (This depends on the year!)

Standard R134a 'quick fit' connectors are used in the compressor suction & discharge pipes at the right side closest to the firewall of the engine bay;
* the low pressure vapour line is fitted in the pipe between the evaporator & compressor.
* the high pressure liquid line is fitted in the pipe between the compressor & condenser.

There is a "''Lotus Service Notes''," "''Section PL''," that goes into '''great detail''' including torque setting for all the pipe work, diagrams, part numbers.

All of the pipes are aluminium, they have a lip on each end, this makes the nuts captive. There are "O" rings these should be replaced if the joint is opened, not all the "O" rings are the same size.
