I've searched and read a few threads about this, but I still can't figure it out. The main spark values are nowhere near the actual. Please check out my tune and log below. Focus on areas where there's no KR, BKR, ECT or IAT advance/retard. The main values are a bit off from actual. What table am I missing here?
Vehicle is a 2000 Sierra, turbo 4.8 with a TH400 (used to be T56) and a 3bar OS.
Oh yeah, the same thing happens while doing a 1/4mi run. I get some KR and BKR, but subtracting those values from the main spark values doesn't equal the actual timing.
