Total Timing = Base Timing + Advance + FBKC + FLKC + IAT Comp + Coolant Comp + etc

The advance table is there to globally change the timing at high loads via the IAM.
That hasn't been my experience, I was having hesitation from too much base timing in the lower rpms 2500-2800rpms and at those cells the advance is 0. When I logged I saw no knock correction, neither fine correction, or a lowering of the IAM. I then just took a look at the base timing map, saw that the column read something like 36 36 36 43 35 35 and of course realized that the 43 is causing the problem. I smoothed out the column and no more hesitation. Try it for ****s and giggles.
