Been looking through this tuning problem lately, figuring it's time for me to dive into this aspect of my car. But man, it's a pretty big chunk to try to swallow. Been reading threads on their forum, but most of those guys are throwing around terms and acronyms that I don't have a clue about what they mean.
I've also been paging through the tune that Mike Carnahan did on my car and comparing those tables with a stock 2002 Z06 tune to see what sort of changes he has done. Of course, mine is a custom OS, since it is based on a 2 bar MAP sensor, but the other tables should be mostly applicable.
Probably will be quite a while before I am comfortable actually making any changes and flashing the PCM with them, however. And I need to figure out how to hook up my wide band so I can take a look at the AFR.
I did some data logging when I took the car out on Friday, and the engine RPM seems to jitter quite a bit when I'm going only 10 mph down my dirt road. The spark advance looks like a saw tooth, so that appears to be kind of unstable. So that will probably be the first thing I try to figure out.
