ZEX has taken their patented TPS activation circuit and placed it in an easy to install, stand alone unit. This switch allows anyone with a non-ZEX nitrous system to enjoy the benefits of using their throttle position sensor to reliably activate their nitrous system at wide open throttle. This unit is self programming and is compatible with all TPS sensors.

Features:

• Switch allows anyone with non-ZEX nitrous system to activate nitrous at wide open throttle
• Works perfectly with throttle-by-wire vehicles
• Fully self-programmable
