    Jagged spark under WOT

    Anybody know what causes the shark tooth looking spark advance when i go WOT? I can't figure it out. I've seen this on one other car. Could it be a bad crank sensor or bent reluctor? or am i missing something simple in the tune?

    2011 Camaro, 224/237 .646/.638 112+4, Airaid intake, stock everything else. Manual trans....it does the jagged spark with or without spark smoothing enabled. I have all torque management disabled and spark modifiers disabled as far as i can tell in an effort to figure it out. Am i not logging something i should be?

    Crank relearn didn't help either.
