Hey all, I'm new to all this tuning stuff. I've got a 2003 Monte Carlo with the 3400 LA1 60 Degree V6, ECU 12209614.. I'm able to use a program like ScanXL to clear trouble codes, freeze frames, and the like, but I'm not able to find really any information on this ECU at all. I would like to tune or do things that ScanXL doesnt do. Any input is appreciated. I don't know the memcal or anything but i do have individual pictures of each of the chips inside the ECU..
