    I am going to plead total ignorance on your OS and Platform. I am a little curious about the High and Low Octane Spark Tables. Is Low Octane Spark supposed to be higher? Is that a DOD feature? Or is that table not in play?

    I know that does not address your problem, I am just curious..

    I was thinking it was a "knock discovery" setting for the tune. I've seen this before when shops go looking for real knock vs false knock. However it's very possible that it's just been missed while tuning.

    Looks like they forgot to reset the low table then. It's not the first time I've seen spark tables like that come out of a shop.
