Thread: Immediate Engine TQ source - RPM limit

    Immediate Engine TQ source - RPM limit

    Ive got a 2018 Camaro 1LE that always runs into a RPM limit at 7000rpm even with all the normal RPM limit tables raised to 7400 or higher. Is there something besides what is under the Fuel -> Cutoff?

    Maybe try lowering the acceleration based threshold table or raising the acceleration based filter coefficient.

    Accel threshold is zeroed out.

    what does your ve and maf look like? make sure VE does not show low or negative values in the problem range, it will feel like you hit a brick wall.

    Max out the commanded limiter tq fixed it so it just hits the extreme cutoff. Its a band aid for now.

    I am asking what it looks like in the tune, not a log.

    I posted that to show you the MAF and VE values when it was happening.
