NEED Help E67 standalone for sandrail ALPHA Fab system DBW problem

Bought Alpha Fab harness and computer for 2008 cobalt 2.2 motor with coil on plug. Everything starts and runs fine until you get on the throttle too fast (I think) it will start to accelerate then loses power and returns to idle. If you baby the throttle by pressing slowly it will accelerate fine, but it doesn't take much for it cut out. Throws P0606 code and if you shut off disconnect battery for a few seconds it will start and run fine again but does same thing.

Back story - contacted Alpha Fab 4 months ago about issue, was told to buy gas pedal matching VIN in ECM (E67) but didn't help. Was also told new ecm was being shipped 10/17, finally got tracking # on 11/2 but still shows never shipped. They won't answer phone, and lucky if I get an email response faster than two weeks, Point is I can't get these guys to fix this and i'm stuck

I don't have any tuning knowledge or hardware, so any help or idea of who could help would be appreciated. I'm in Phoenix, AZ area.

That code means the ECU is bad

That code means the ECU is bad

The GM Service Manual will tell you that, however in practice, that is not always the case.

A P0606 code will also set if there is a mismatch between the APP (accelerator pedal), the throttle body, and the base programming (by GM software) in the E67.

Flinttownchopper, you posted this problem on the EFILive website awhile ago. You stated that you do not own an EFILive nor an HP Tuners programming interface - it is a bit useless posting on tuning forums for support, when you cannot provide the tune and a log of the problematic event for people to review.
