Thread: Decel pop

    Decel pop

    What area do you concentrate on to get rid of decel pop, 6spd manual pops when decelerating in 4-6 gear below 3000 rpm.

    Thanks

    While still trying to eliminate decel pop, another curve, looking at several maps, Minimum spark table, some are RPM vs aircharge and some are RPM vs MAP KPA, what's the difference ?
