OK guys, its been about 2 weeks that I'm trying to figure out why my 85 350 Vette chip apears to no be compatible to my 85 Z28 TPI that has now a 350 (all sensors/ECM stuff is from the old 305)
Any ideas?

Symptoms: Car will start, idle bad (like too rich) check engine light is on, and when I try to red the codes with the paper clip, the light stays on and won't flash. Runs fine with the hypertech 305 chip, ecm flashes 12...

 

That wont work you need to run a 305 chip because the vette computer has a extra sensor that the camaro dosnt. Not shure what the sensor is but I know it dosnt work........
