I am having major problems with my config files that were posted under the sticky... Only half of them work... I cannot get a consistant STFT error table so i can make ajustments... I am running 1 bar SD on a 6.0/4l80 OS with a factory MAP sensor... I have had O2 sensor problems with the truck but feel like they are close to fixed Last night i made two 10-20min scans for setting up the VE today its about 20 degrees Hotter and stft at idle at -32%.... is there something i am doing wrong?.. so u need to use a NON MAF config file to keep up with my STFT??.. I was pretty sure it was all the same..... or if anyone has a config that i can try .. I will make scans and post the results...
