Tired of... Having to replace RPM pills every time you want to change the activation RPM of your nitrous kit? Needing two RPM-activated window switches to control 2-stage nitrous? Well now you can rest at ease.
Compatible with 4-cycle engines from 1 to 12 cylinders, Nitrous Oxide Systems is proud to present the 2-Stage Wide-Open Throttle/RPM Activated Window Switch with shift light control. It is compact and user-friendly with an easy-to-read display and two programmable RPM window switches that can operate from 0 to 20,000 RPM. Because it works independently of TPS, the switch can be used on carbureted or EFI applications.
Off/On RPM can be programmed from 0 to 9999 RPM in single RPM increments for precise control (reading is x10 for applications over 9999 RPM)
RPM input can be connected to a DIS coil driver wire or tachometer output circuit
Reads rising/falling TPS (throttle position sensor) signal for accurate activation every time
TPS trigger voltage is adjustable from 0 to 5 volts in 1/10 increments
Use the display to recall/view maximum RPM and TPS voltage for a simpler setup on your next pass
Shift light control is adjustable from 0 to 9999 RPM for on-time shifts
Bright LEDs light up when stages are active
Ideal for drive-by-wire vehicles that don't have throttle cable to mount a traditional activation switch
Can be used to activate other accessories, not just nitrous
