A used M57 218 ECU.
This is suitable for E46 204hp engines and can be configured for manual or automatic (GM) gearboxes.
This ECU can be purchased to be deimmobilised if you do not have an ECU to send. It is given a health check by us, however the casing will show signs of use.
We only recommend this ECU to be used in a conversion application and not in a BMW car, as it may not have all the functions of full car activated.
If you purchase this ECU without the deimmobilising service then it would not work unless it is coded to a new immobiliser.
We also recommend our tuning service to get the full rpm range and full potential of the engine.
