    PE/COT Advance timing pull

    So I am tuning my 2018 Camaro SS on E85 and I am working trying to add in roughly 2 degrees of timing, but the issue I am having is the PE/COT advance is pulling more timing than I'm adding. I had the tables stock, and then zero'd out the alcohol table in the areas affected. I thought this would take care of my issue but it still pulled the same amount out, except this time it was less above 6200ish. It's got me baffled why it's doing this as it doesn't appear it is affected by the multiplier at all. Also note I have the COT Disabled. So I'm hoping someone can steer me in the right direction.
    Thank youGasoline PE table.PNGEthonal PE table.PNGAttachment 122907

    I might have answered my own question as I think I'm thinking of these tables backwards. I was thinking lambda value but it's EQ so richer is 1.2 which would make sense.

    You are correct, the row axis directly references your Fuel PE table commanded EQ Ratio.
