Hi Eric, I recently went from a TT 6.1 chip to the ECU GN. The car runs fine until the A/C compressor is turned on and I press the gas . Once I press the gas or tap it (with the A/C on), the car boogs down then dies immediately after the gas is released. It does it constantly and consistently every time. I have included a log where I have turned the A/C on a number of times and it has died every time back to back. Do you have any ideas from the attached log of any adjustments that may need to made? Note: There were no issues with the A/C compressor and the car dying with my old 6.1 chip. P.S. I tried to send the log, but looks like I cant upload an .msl file. I can email it to you if you like.
