    Lowering Fuel Cutoff Resume several hundred of RPM's

    Typically Fuel Cutoff Resume rpm's seems to be just a tad lower than the actual limit.

    Does anyone have opinion why it would be a problem to lower the Resume rpm for something like 1000 rpm from the redline? Especially with meth injection, since it will not stop spraying as there's still boost condition with supercharged engines at WOT.

    The reason for this kind of behavior is that during sudden loss of traction, some cars seem to have tendency to break belts while running against rpm limit. I guess it would help if Resume rpm would be lower than normally, i.e. not that violent behavior against redline.

    Not a good idea on a methanol injected car because while the car is on the limiter (Fuel Cut) the methanol will still be spraying providing a fuel source in the chamber... however it's not enough and if ignited could cause damage. It's probably not enough to hurt anything if you have a smaller methanol kit but some of them spray a significant amount of methanol into the engine.
