Thread: 2-Step Staying On

    Default 2-Step Staying On

    Having an issue using the Rev Limiter #1 for my 2-Step pinned to my transbrake button. When I release the transbrake the car launches at the desired RPM, but holds if for about 2.5 seconds after transbrake is released. Hopping someone could point me In the right direction. I’m running the HP ECU, 6.8" Pro Dash with V6 EFI software. Thanks.

    Default

    For the most accurate transbrake release when bracket racing, I (and others I’ve viewed) assigned this task directly to the ignition (MSD GRID for me) and leave HP handle the injectors.

    I run dual fuel systems (93 octane in a spray bar and Methanol in EFI) and do not let HP control the ignition timing. Grid controls all ignition timing functions using its own crank trigger, and HP controls MPFI using a separate cam & crank trigger.
