Ghetto 2 step?
So I was pondering something and wondered if anyone had done this before.
So if the maf signal doesn't make it's journey from the maf to the ecu you get a safe mode type thing where the rev is limited to 2500 rpms. What if you then interupt the clutch pedal switch with said signal. You would have a ghetto 2 step. Anyone done this? I haven't just theorizing and all. |

no maf means "safe mode" and goes richer. turbos like the right a/f to spool correctly and at 2500 and extra rich, it probablay wont spool well.
its an interesting idea though. |

I see in no way that this could benefit you for drifting. Please enlighten me.

Doing this rev limiter the way the op is saying (I have seen people do) but it is not the best thing. Depending on your turbo you may see up to 1 psi of boost, however it is going to be very very lean. The only way I could see this some what being of a benefit is if you liked to drag race some and wanted to hold your rpms at a steady rev (not full throttle but at 2500) just so you have a consistand launch. 2500 rpms is still slightly low to launch at imo. |

All good points. That's why I asked first . I was thinking of drifting because some times while sliding I have to tap the gas a few times to keep the revs up. I was thinking it would eliminate it by just stomping the pedal instead of taping it repeatedly. Or clutch sliping. But anyways not what I was looking for. I figured I would discuss before a try and do something bad to a motor I can't afford to replace.
