    Timing and Rev Match

    I noticed that when Rev Match is engaged, ignition advance stay down in the 15 degrees range until ~2200 rpm at 20% throttle. Then suddenly jumps up to ~39 degrees. There is a jump in torque. Very irritating around town.

    HOWEVER, if Rev Match is disengaged, it doesn't happen.

    I've looked everywhere and don't see anything pertaining to rev match and timing.

    I have felt this jump in torque without rev match engaged. It's random and I do not think it is caused by rev match.

    What did you do with your torque tables? DD, peak torque, airmass, etc?

    I added to do various tables but didn't seem to make huge difference

    Put all your torque tables, including DD back to stock.

    I did.

    I only tuned the MAF and set P420/P430 to do not report.
