I know, but still a lot of good info.. Until I hear more about the ECU reverse-engineering project I'm not going to make any definitive statements.
From my experiences(I'm getting afrs in the mid 11s @ 10# on a very-close-to stock fuel system) I tend to lean toward the "it only affects timing advance" theory. I think load is determined off the AFM & TPS moreso.
There were hints though, and the guy had hard evidence, that injector pulse-widths are also affected by the boost sensor. I can't find the thread now & it was on the other forum anyway.
It's kinda nice to have a car with such a following. Pretty much everything has been addressed over years. I don't know if I've ever known one of my rigs better than I do with this one, and I've only had it for about a year and a half.
