Thread: 2-Step Rev Limiter on Transbrake

  1. #1

    Default 2-Step Rev Limiter on Transbrake

    I have my Rev Limiter setup at 4000 & 3850 RPM, and set as "soft". Looking at my datalogs, my car is extremely rich while on the 2-Step/transbrake. When I let go of the transbrake, the closed loop kicks in, and it starts recovering. But it takes a little over a second before it gets close, and then overshoots, and has to correct again. My question is, would I be better to try changing the type from "Soft" to "Fuel & Spark"? Or is that not the right way to do it on 2-Step?

    It's usually best to do a "Spark Only" Rev Limiter while on the transbrake.
    It will always go pig rich on the Rev Limiter.
    The Soft Rev Limiter is best suited for a burnout box limiter or a Main Over-Rev Limiter.

    ButchB, did you ever figure it out? We had a similar problem at the track yesterday. It seems like it loads up on the transbrake then sputters right off the line.
