What are you doing for idle? Does your ms3 control the drive by wire throttle? How did you get the ECU to not limp when the MS3 is controlling everything else?Yes, 2 years now. Haven't finished all my "want to do this and that" but is full functional. every day use.
I dont know the Siemens, but I know it is a different story. There are guys here that turboed facelift SLKs, Cs, I ll try to make a contact with them to learn more about the Siemens, but I know there are no standalone ECU projects.
