So you set at 3000 for example, to control wheelspin and no matter how hard you press the throttle, it revs only to 3000, right?
So during this time, all your excess, possibly unburnt fuel is going into the exhaust....
Is this a possible fire risk?
How does the unit remove the rev limit control, once you are rolling? Surely you don’t have to flick the switch while you are trying to keep the car straight?

With a clutch car (manual trans), you fit a switch to the clutch pedal, and a relay circuit, we'll go into that later, that allows the desired rpm limit with the clutch pedal depressed.
So while staged at the lights, the rpm will hold at the desired limit.
It is a soft limiter, not a hard limiter like the high end.
It drops cylinders as necessary, but fires them on the next cycle, so each plug doesn't foul. It gives crackling exhaust etc, but that's part of the fun.
Others will know what is happening when it does occur.
