I have a 2002 silverado that originally had a 4.8l v8 in it that went bad. I purchased a 6.0l lq4 with a kenne bell 2.2l supercharger out of a 2003 hummer h2. I was given the hummers pcm when I got the engine and was able to plug it into my truck and extract the tune file. I used the compare tool and swapped over all the data and it was running pretty good. I needed to convert to a 2 bar os and was going crazy trying to figure out how to do it and came across a post stating I needed to be in advanced view, not basic. I didn't know that and found a lot of other stuff that needed to be changed as well. After I swapped all data over, now the truck won't idle and floods out. I changed all idle air control back to the 4.8 numbers thinking it was a difference between the etc and drive by cable. But it made no difference. Is there something I missed? If anyone could point me in the right direction, I would very much appreciate it. I left my laptop at work so I can't share the files, but I will as soon as I get to work tomorrow. Again, thank you to anyone that has any advice.
