Universal Two-Stage Window Switch Activated by RPM / Throttle (WOT/RPM)

Tired of having to replace RPM pills every time you want to change the activation RPM of your nitrous kit? Or of needing two RPM-activated window switches to control two stages of nitrous?

NOS presents its two-stage wide-open-throttle / RPM-activated window switch with shift light control. This compact, user-friendly unit offers two fully programmable, independent RPM window switches that operate from 0 to 20,000 RPM, from low-revving engines to high-revving sport bikes. It reads a rising or falling throttle position sensor for accurate activation every time. It also has a programmable output for a shift light and a recall function that shows maximum RPM and TPS voltage for easy setup. It is also supplied in kits 02121, 05134 and 05135.

Window switches have just been taken to the next level.
