Should I be using fuel cut for RPM limiter on my 500wrhp Fd?
Did some research and found some for and against. I've been using fuel cut as opposed to ignition cut. Is this recommended?

It works for me; I like the fuel cut method--it feels cleaner and less ragged. I've been flat shifting against this type of rev limiter for years with no problems whatsoever.
|
Are you using hard cut or soft cut? I am using hard cut
|
If you are on premix only i wouldn't recommend cutting fuel.

Jetlude--I'm using hard cut.
(Lube is premix+OMP, fwiw.) |

op, make sure your injector phase is set right, or you could cause a lean condition |

Injector phase. Assuring that each spray of fuel is fully drawn in by one intake cycle. Not over lapping. If tgey are overlapping, you can still have good afrs. However, when you start pulling individual pulses, it leaves a partial pulse to be drawn in, thus a lean condition.
