Activate and deactivate circuits at pre-programmed rpm windows with this MSD switch. It is especially useful for nitrous equipped engines, because the nitrous system can be shut down just before the engine's high rev limit.
The window switch includes a ground to activate a circuit, and handles up to 1.5 amps. Revs adjust with the same plug-in modules used on other MSD rev controls, and is compatible with stock inductive ignition or hi-po capacitive discharge controls.
I have used this on my car for my nitrous, it worked great. Although I sold it because my nitrous setup is automatically controlled by the throttle so I really had no use for it. It did what it was supposed to do though, turn it on and off with different "pills". I would definitely recomend getting this if your nos isnt throttle controlled so it doesnt damage your engine.
