We were just talking about that happening at the last meet. My cobb OBDII plug would always come loose. So it came down to tapping into those wires and stringing a serial cable up behind my cluster, through the dash, and down into the center console.

Sounds like the AP got through the erasing process but didn't write, so you have a blank ecu. I'd give Cobb's support line a call and maybe shop around for a new ECU.

cobb said that the AP2 has a recovery mode which is suppose to uninstall itself and program the factory map back in the ECU and then your suppose to reinstall the AP again. But thats where my problem is the AP wont connect to the ecu to uninstall. I just tried another AP cable setup to from a friend and it still had the same problem so I am on hold with cobb right now

Well that's good though. I'd imagine they can reflash a dead ecu if they had to.

Damn, that's cool. A ton less than buying a new ECU. Let me know when you get it back.
