Ensure your nitrous is spraying at safe RPMs with the Nitrous Express RPM Window Switch. The Window Switch prevents you from accidentally injecting nitrous into your motor at engine damaging, unsafely low or high RPMs. While an optional add-on, this item should be standard on all nitrous installations for safe operation.
This innovative module monitors engine rpm as well as throttle position to automatically control nitrous flow based on user adjustable RPM and TPS values.
The large LCD display is easy to read and the setting can be quickly viewed and changed without the use of a laptop. This module is compatible with all 1 to 12 cylinder engines with coil on plug, waste spark or distributor equipped ignition systems
