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...

Mostly to give you a response and some background.

Most here haven't done a custom 95 burn and needed to scan for certain info. Not knowing what he'll need/change is difficult and you may want to contact him for the exact information he needs to ensure success.

Only other person that I now of would be 95NASTA. I'm sure he'll see this and post soon.
