I'm running an 05 pcm in an 07 GP n/a. Just installed headers yesterday. I've been trying to get this pcm running properly for about 2-3 months now, and i keep switching it back to stock (the 07 pcm cannot be tuned). I am running into the following issues with the 05...My fuel trims seem to be stuck at 16.4, but are not that way all the time. I am getting lots of KR (up to 8*) at medium throttle levels. I am wondering if someone can take a look at my scan. I have attached my scan and the tune that i have on the pcm. I also need some information on how to get out of VE tuning. I have heard that i should not be tuning with VE. I can't seem to figure out in the program how to change it. Am I having a vac leak? Is it just a cat diagnostic? Why am i getting less than 16mpg's on an n/a vehicle???
here is a link to my scandepot page. todays scans are may92010-1,2,3. thanks!
