    Interesting. I noticed it took longer to recover some times. This explains it.

    they are all under spark tab; under fuel, humidity, VCT and MBT corrections.
    After this modification you will get the exact timing from high octane table.
    Just after flash open the door and cycle the ignition then you are good to go.
    You can keep ethanol/alcohol tables working if you use e85.

    This has wasted so much of my time!

    You are the man! Thank you Sir.
