probably too much advance timing or the wrong octane fuel would be my guesses. your o2's aren't that high. low 900's is good. the long terms at zero is great. i am sure some tuning experts will chime in to help out as well.

i was only commanding like 12deg. it dropped below 5. i'm thinking it's got to be my harmonic balancer/crank pully rattling, or a fuelling issue. christ, it's not like i'm asking for 22deg. I'm lost. the other thing is, could my alcohol injection be causing the problem???? i know it messes with a/f.

How high are you revving it? At 21 ms you are out of injector at 5700rpm.
