Title: Can a ME7.5.1 ECU with chip on riser be returned to standard tune? Post by: mech0001 on October 14, 2025, 05:56:04 PM 2001 Audi TT 225 Quattro with a custom tune for methanol injection.
Injection system (Aquamist) has failed and want to return to standard tuning. I have tried NefModo, Galletto, and CheckMate with various failures. Was able to read the image with NefModo but flash failed. Galletto never connected. CheckMate reported EOF errors detected in python code. Not sure whose code or which data is wrong. Main issue seems to be getting into boot mode. Grounding the ecu pin referenced for other (non-riser) ecus does not seem to be working. Not sure what my next step should be and wondering whether the riser prevents reflash. Thank you in advance! Title: Re: Can a ME7.5.1 ECU with chip on riser be returned to standard tune?

or get replacement ecu Title: Re: Can a ME7.5.1 ECU with chip on riser be returned to standard tune? Post by: mech0001 on October 15, 2025, 02:02:40 PM Thanks! PCB chip soldering is not my strongest suit but I'll give it a shot.
