Hi everyone,
I am currently working on Opel Astra G 2.0T OPC, trying to collect knowledge to start tuning my car - rev limit., boosting issues, 2nd O2 sensor off etc.
Don't know much about checksums or how to flash a tuned map to ME1.5.5 without bricking it (MPPS) :| :D
I learned something about MS43 ECU's, but the MS4x forum is HUGE, you find everything, but this Opel checksum and map madness is really terrible.. :think:
