The [[Emerald]] M3DK is a plug compatible replacement ECU for the Rover MEMS unit used on the K series, it utilises the existing engine sensors and works with distributor based systems and distributorless 'wasted spark' systems. It is compatible with the immobiliser as fitted to Elises and Caterhams. It is fully programmable and comes complete with software, manual, comms cable and example maps. It has user tailorable soft and hard cut rev-limits and a user programmable shift light.

== ECU mapping ==

If you make substantial changes to your car setup or simply want to ensure that the ECU is correctly configured to control the fuel system, then you could consider a "mapping" session on a rolling road.

ECUs generally work by comparing the engine speed in rpm to the position of the throttle. The ECU then compares these values on a "map" to find the correct amount of fuel to add. This ensures that an engine is not running too rich or too lean, both of which can be undesirable with the latter leading to detonation.

The mapping process will involve your car being run on a rolling road for a period of time, with an operator changing the map on the fly. The rolling road will then allow the operator to add the optimum values to the map.

[[image:M3DK.JPG|thumb|left|Emerald M3DK]]
The [[Emerald]] M3DK is a plug compatible replacement ECU for the Rover MEMS unit used on the K series, it utilises the existing engine sensors and works with distributor based systems and distributorless 'wasted spark' systems. It is compatible with the immobiliser as fitted to Elises and Caterhams. It is fully programmable and comes complete with software, manual, comms cable and example maps. It has user tailorable soft and hard cut rev-limits and a user programmable shift light.

== ECU mapping ==

If you make substantial changes to your car setup or simply want to ensure that the ECU is correctly configured to control the fuel system, then you could consider a "mapping" session on a rolling road.

ECUs generally work by comparing the engine speed in rpm to the position of the throttle. The ECU then compares these values on a "map" to find the correct amount of fuel to add. This ensures that an engine is not running too rich or too lean, both of which can be undesirable with the latter leading to detonation.

The mapping process will involve your car being run on a rolling road for a period of time, with an operator changing the map on the fly. The rolling road will then allow the operator to add the optimum values to the map.

Traction control

2008-03-08T20:57:17Z

PAB:

==Traction Control==

Wikipedia On [http://en.wikipedia.org/wiki/Traction_control Traction Control]

Offered as an £395 Option on the 06 Elise and Exige onwards.

A switchable Lotus Traction Control System (LTC) is available for the first time on the Elise and Exige for 2006. The LTC works through the engine management system to reduce power when required to maintain traction.

Unlike many traction control systems, LTC has been tuned to complement the skills of the driver without taking over. The Lotus LTC is active above 5mph and operates much more quickly than many brake-based systems.

The system can be deactivated with an illuminated button which is located adjacent to the gear lever

The Lotus Traction Control system is activated via the Lotus T4e Engine Control Unit. It is fully developed in-house at Hethel by Lotus Engineering.*

The Traction Control is also available from Lotus for the Toyota T4 (2005) Equipped cars.

*The Traction Control was NOT developed by RaceLogic

'''VARIABLE TRACTION CONTROL'''
First available in the "Launch Edition" 2-11.
Option on Exige S models (Model Year 2008)

Consists of a rotary knob (like that on the heater controls), which adjusts the setting of the traction control system.
Adjustable from no slip (0%) which is default setting, incrementally upto 10%

Malfunction indicator lamp

2007-03-12T21:42:45Z

PAB:

The '''Malfunction Indicator Lamp''' (MIL) is provides to warn the driver that the engine management system has detected a fault which may result in increased toxic emissions from the exhaust.
#If the lamp lights steady whilst driving, dealer advice should be sought without delay, and all unnecessary journeys avoided.
#If the lamp flashes, an engine misfire has been detected which is sufficiently severe to cause overheat damage to the [[catalytic converter]]. Slow down immediately and be prepared to stop.
#*If the '''MIL''' then stops flashing, and is lit steady, proceed with caution and seek dealer advice.
#*If the '''MIL''' continues to flash, stop the engine and seek dealer advice. Continuing to drive the car with a flashing '''MIL'''may cause overheat damage to the [[catalytic converter|exhaust catalyst]] and increase toxic emissions.
