ok, here we go. I read the flash that was in my pcm. I'm sitting here comparing it to a 08 cobalt tune (allegedly stock) from the HP tuners repository. There's some tables in my PCM with values that are making me think there was some tuning done on the saturn sky that my pcm came out of. In the pictures that will be in this post my tune is on the bottom and the cobalt tune from the HP tuners repository are the values on the top.
The MAF settings are both pretty different
MAF correction
Max tq vs RPM vs Gear
Boost control.
Are these the changes that need to be made when going from stock map to 3 bar map?
I've been running this tune on all stock parts. I did buy the 3 bar map sensor at the same time that I purchased HP tuners. I need some input from the more experienced people on here if it looks like this tune is set up for 3 bar maps. If it is I'll install them and see how it drives at that point. Also wondering if I'll be better of copying in the stock 08 ss values into my tune and using that as a better starting point rather than trying to mess with my mystery Sky tune. I was surprised to see the max tq. VS RPM VS gear to be set at 100% for all the cells on my car. I would have though the car would have been much more unruly in 1st gear than it is currently. I'll attach my tune file as well if anyone else wants to look at it.
