Hello

Need help with EGR OFF in my Vectra C 2005 Z19DT (EDC16C9)

File is was modified and now car has 150HP but EGR fault start to appear time to time.

Tried EcuSafe and Volta, but no joy :(

I know in this ECU egr off is by hysteresis but my knowledge ends in this point...

File from MPPS 13.02, i don't have BDM.

It's possible to proper OFF with MPPS or I need full BDM Flash?

Best Regards,
J
