    Did some more testing and the condition does not necessarily happen same RPM every time, however I would say seat of the pants it feels like motor is under same type of load whenever it happens. Interesting though I was able to feather the throttle up close to 2500 - 3000 and then floor it and it revved out without the pedal cutting out. Looked for freeze frame data from my computer using "car scanner" but nothing logged for the P0606 code. Not sure if this helps or even means anything...

    Try disabling some of the ETC sanity tests (set the enable parameters high enough to not be attained).

    Alpha Fab sent new E37 ECM and a new harness since I had an E67 - Took way too long, but he made it right and now it runs great

    Hey, I'm brand new here and I have a question? I didn't know where else to post but this thread seems to be similar to what problems I have been dealing with. I have a 2006 2.2 ecotec from an impala with the E37 pcm. It has coil on plug ignition with FBW throttle pedal. It also has the 3 pin crank sensor. I was told by Phil at Philsbugshack he could tune these with no problem. Unfortunately he retired by the time I was ready to start my project. I had the pcm tuned by another company and tested it out on my boat. It ran good the first time I started it, but after a few starts and runs the engine is surging and can't seem to find idle, there are no codes in the pcm. After a few minutes of running it starts to throw 1ft flames out of the catalytic converter. I put a scanner on it and the Map sensor never changes from 13.1 during idle or at 4k rpm. I'm just needing some advice and help if anyone is familiar with this year and pcm. I was told by Alpha they could not tune this particular 2.2 due to the 58x reluctor and 3 pin crank sensor. If anyone has any information at all I would be at you service.

    Thank you.
