A used M57 204 Euro 4 ECU.
This is suitable for E46 204hp euro 4 engines with the electronic turbo. Manual gearbox only.
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.
