This LNF is like rocket science to me. The cel will tel me I have a map issue, so I change it out, and it's still there. WTF???

I've heard about the airboat with the LNF engine, and I hope I can find someone in town that has that level of knowledge to help out.

Again, thanks for the compliments and for contacts for help. I really appreciate it!!!
Do you have bosch MAP sensors? Or are they the factory ones?

It could be a boost leak or a wiring issue, or O-Rings.

OP- make sure the wiring to the MAP sensors is ok. There are 2 of them, one should be in the cold side charge piping and one should be in the manifold. Check to see which ones they are as well, if they are blue they are 3 bar MAPs and they need a special tune file. If they are grey they are stock ones. There is a known problem with the 3 bar MAPs concerning the wiring of the harness, if a dealer installed them in the car it was pulled out of they may ahve only used crimp style wiring connectors instead of soldering them together. I am pretty sure Terminator2 can tune that thing with or without the BCM connected to the car. The VATS system just needs to be calibrated I believe. If you want an HP tuner in the Vegas area hit up Joe or Chris Warner. They are both on here. Chris' S/N in Warner and Joe's is 07SSYellow. They have a HPTuner computer and should be able to get that thing going. PM Terminator2 on here as well just to see what might be needed as far as tuning without the BCM. HPtuners will be able to tell you more about what is wrong with the tuning anyways, because you can see what the computer is seeing.

Good luck, and if you have any questions let me know I'll try to help as best as I can, as long as I can get a ride in that mother effer later hehe.


I too need some help with mt 09 Cobalt tune. Any updates on the Warners?

Neither of them still own a Cobalt, and I own the HPTuners set they used to have.
