PQ,
I don`t know if you havve looked into this or not but this was a problem w/ my car after the Whipple install. I would assume it would be an issue with any blower and any early 2010 that has not had a updated O/S from GM. Runs great for a minute or so while in open loop hits closed loop and dies. Here is what I said and the fix. not sure if your problem but something worth checking: One thing that is very important that we found out the hardway. Please read the following as it is very important, I would assume for almost any blower install but this was definetly the case with my Whipple. I had taken off work to do this build w/ my friends, the first thing we did per whipples instructions was try to dowload the superchips tune in the car. did not work. Instead of calling whipple then we chose to continue with the job, pretty much had to get cracking as 1 freind took the day off too to help. We got it all done and attempted to install the tune again, called superchips that sat morn and no one was there, spoke to Jeff at Whipple who sent us some HPtuners tunes as we had plans on doing the fine tuning w/ HPtuners since my car is not stock and the superchips tune was for stock. Once the car went into closed loop it would not stay running. We tried everything, nothing worked my tuner came over no dice. Called superchips mon morning they said my Operating system in my computer was not supported by them. I have an early 2010 VIN ends 12,546 and I have never had an update done by GM to my PCM/TCM. My tuner tried and tried to get it to stay running w/ tuning in HPtuners. However, there were tables missing from my PCM that were in other peoples Whipple tunes who sent them to us trying to help me. Thanks again everybody. Well the table that was missing is the Air/Fuel Ratio Analysis program. Its not in the old OS, but is in the new OS from GM. I can`t understand why GM shipped cars w/ out this table. I guess they did a patchwork to get them to run NA, but boy it sure won`t run w/ the blower. Runs fine is open loop, hits closed loop let of on the gas floods out and cuts off no matter what you do. So I took the car to my dealer freind, had to tow it, they flashed it. Starts up runs and drives fine. Disabled AFM and drove it home. Crazy. So the moral here is if you have an older VIN w/ no updates, go weeks in advance and get your car flashed by the dealer w/ the updates. I have been through this pain for you. Don`t make the same mistake....Lol.. Link: http://www.camaro5.com/forums/showth...hlight=whipple

It sure looks like when it begins doing its short and long trim and computer is trying to make its adjustments and running its tests that it is pulling out all the fuel....thus stalling. When you get it to your tuner I am sure he will see it trying to make these huge adjustments. Then the problem is to determine the reason why. Hopefully, it is just in the tune itself and he can adjust it so the tests dont attempt to pull as much out..Or maybe just the front 02 sensors turned off or something. You are so patient with all of this...I probably would have been across the county in Tx having Andy checking it out for me by now.

Yes, but you are under very different circumstances now. Anyways, it just take a second to check. I read the PCM flash post, that really sounds like the problem right there. I hope you get it fixed soon. You know all this pain is gonna be SO worth it when you are done and when you get that win over GTAHVIT!!!

Should be able to plug the VIN in there to determine the O/S and updates available. |

The GMRulz post makes sense, hope that's it. Guess the first thing would be to check and see if PQ has an early modle.

crap, it must be locked down to dealers. I'm getting the same error with my VIN. If you want to pm me the VIN, one of my neighbor friends is a Chevy service manager. He can access all the tech assist stuff at home with his ID. He's looked up bulletins for me before on weekends, so he should be able to do it if you need it looked up today.

If you were an early vin and have taken your car in for the air conditioning "freeze up" flash then it has been updated already for you. If you bought it after the service bulliten for the air conditioning and I think the heater hose fix then it was done before delivery. It would be very rare to have not already had this done..If I remember this only had an effect on 30000 and under vins but cant be certain on that...sunday morning brain freeze and too lazy to look it up.
Good point to raise though. Once you have a tune installed place tape over your obdII with a warning to the dealer not to flash unless they talk to you. They will load a flash over the top of your tune and set back to stock and then you wont be going anywhere. In my case I am converted to E85 and the car would not even start on a stock tune and would be dangerously lean.

Seems though - if the actuator was opened, stock injectors, and OE tune it should idle normally if nothing else was wrong.

Yeah you got that right....Air is off somewhere or a sensor is sending info to the ECM causing it to over adjust when the trims kick in. Either the maf or the 02 sensors something is reading invalid data and messing with the fuel.
