Welcome to my auction, here I offer a service to remap your BMW E36 323i ECU. This can include EWS immobilizer function delete and is tuned to an impressive 205Hp when using the M50 325 intake!
It is for Siemens MS41 ECUs used in cars equipped with the M52B25 engine. This will work in cars with a manual or automatic gearboxes. At the time of the remap the ECU will also be updated to the latest software using genuine BMW service tools and the adaptations are cleared at that time. The ECU will need to learn new adaptation so the idle may be unstable initially. Due to the nature of the automatic gearbox the power gains will be less noticeable in those cars. There is no difference between the ECU for a manual or automatic gearbox.
Deleting the EWS is perfect for track cars, engine transplants or if you have any other reason to remove the EWS immobilizer. It also makes this ECU plug and play. This EWS delete in this ECU is a pure software modification, not a hardware hack, so it will never fail. If you want to remove all the EWS parts from your car, you will need to connect pins 1 and 3 in the EWS module loom to have a permanent connection from the ignition switch to the starter solenoid.
Stock ECUs will run in safe mode limiting revs to 5500rpm if the ABS/ASC system is removed such as in a car transplant or track car. This ecu has the ABS/ASC signal requirement disabled so will rev to the full rev limiter with no ABS/ASC in the car. In a car with the ABS/ASC system in the car it will work the same and not effect the functioning of the ABS/ASC system.
