I have just noticed this advert on ebay for a diesel engine ECU that has had the immobiliser programmed out.
Anyone heard of this before? and how is it done?
The Bosch engine ECU has a fixed EMS code stored in it. It is set at the factory and cannot be altered. The BECM reads and compares the code and sends a start signal if they are the same.
When an ECU is chipped with a different performance map it does not alter this code, it is stored elsewhere in the ECU.
