Actron Tool and Tuning Help
I have a series I L67, a scan tool, and need a custom PCM. I have spoken with Darth Fiero, aka GM Tuners, aka sinister performance. He said that I need to provide him with scan data for a tune. I have only the limited scanning time available on my scanner, and I do not know which are the key numbers that he needs. He sent me a list of a few numbers to get him, but it seems that my tuner has less information than he may need. I can scan knock, temps (coolant, inlet air...)
Can anyone with an Actron scanner tell me what the most important numbers are for tuning, and how to record them with enough data for a reprogrammed PCM? Thanks for the help...
