I have an 04' Saturn Ion RL. I just installed 2.9" ZZP pulley and 60# injectors and switched to e85. After reflashing a tune into the car, I have lost the function of my cruise control, along with while in vcm scanner, I can't get it to log rpm, injector DC, boost, and a couple other various pids are saying unsupported. I have visited the config repository and downloaded 3 or 4 config files in an attempt to do some trial and error.
I have tried an write entire to correct the issues. I have went back to a stock tune and edited it from there. Nothing seems to work. I am hoping its something simple and a light bulb will come on for one of you with a lot of experience.
The car drives just fine with the base can tune but I know it needs tweaked and edited to be correct for the car. Any input is welcomed!
