    To the OP, thanks for posting you factory bin. I snagged it for storage. I had not saved a factory bin from my Z28 PCM before I sent it off to a tuner. I've since been tuning my own stuff but it's nice to have a stock F body bin to look at if I need to. Especially a TA bin because I might be adding the performance mode for transmission stuff.

    I can't figure out with detonation in PE mode.
    Main spark table is modified, but it seems to be almost okay.
    Extended spark table is stock. Retard @4200 is up to 10 degrees. Commanded afr is really rich in PE. ~12.0 . It should be at least.
    Im running 93+ octane. MAF car. No vacuum leaks.
    Short eehack log below. (remove ".txt")
    any ideas?
