[jd4242]

anyone know how the rev limiter is done on a OBD1 1992?is it done by fuel cut off or spark cut off?i was told it was done by fuel cut off.

Its a fuel cut-off.

Thats what i was told.so assume it just cuts power to the relay?

I dont think so. I think on the sequential, its cuts out every other injector. On the batch fire, it cuts out each bank every other time it should fire.

If it just killed the power from the relay, the engine would stall.

Aww man!!that sucks.my idea was to wire the fuel pump relay to the shift light so i could set the rev limiter to what ever i want.i would shift right before the light came on and cut power.so thats out the window now
