The Nitrous Express DIGITAL RPM WINDOW SWITCH (Now for all ignition types, No RPM chips required) (part 18959) is designed to monitor or control the listed electrical or pressure function in a performance system. The NX Digital RPM Window Switch keeps the nitrous from activating at low RPMs and shuts off the nitrous before you over rev and/or hit a revlimiter. This new Digital design allows you to set high and low RPMs quickly and easily without changing pills or chips. This item is intended for universal / component-specific application; verify engine rpm limiter requirements.
