Thanks. You changed three single values in flash section. Does this mean that I can write the change through MPPS Bench?

Thanks. Same changed three single values. Obviously, this is the solution. :)


I will test it, but before that I'm looking for information on what will happen if I replace these two ECU-s with different family reference numbers:


My working ECU: 0281013138 EDC16C39-5.65 55204661


Spare ECU from ebay with your immo off: 0281015160 EDC16C39-6.65 51821929

OK, I tried these three single values change and it works. Thanks.

After manually transferred all my Stage 2 changes into the new ECU, the car starts and works on idle but can not be revving the engine.
