I am so excited to be able to ask for help on this. I have been putting this Z28 for a long time. I got it with a spun bearing, but I gotta put a bigger cam in it, and injectors, and LT headers, light port match on the intake side, used roller rockers that might be 1.6 RRs. So it doesn’t idle anymore unless i give it a little gas. It does start and run tho. I did manage to download the bin and start working on it. For the easy stuff like AC delete, air injection delete. I just need to know how to tune this thing now. Any help or guidance and or direction would be greatly appreciated.
