next, spark. here is the quick and dirty map:



what do we see? at partially open throttle, it advances nicely. once i hit 40%+, it looks to me like the car is pulling timing. i have to read up on spark maps, but i would think at WOT and heavy throttle, the timing would be in the upper 30's / lower 40's.

it's possible the knock sensors are sensing one of many things. my car is stripped out and LOUD as hell. race exhaust, no cats.
