Product Description

The Nitrous Express 15961 TPS Voltage Sensing Full Throttle Activation Switch is a universal electronic activation accessory designed to trigger your nitrous system precisely at wide-open throttle. It uses throttle position sensor (TPS) voltage to detect when the engine throttle reaches a preset level, ensuring nitrous is engaged at the optimal moment for performance. The switch features a self-programming "Autolearn" function that simplifies calibration by learning your throttle's voltage range with the push of a button.

Constructed for durability and reliability, the 15961 comes complete with an adjustable switch module, heavy-duty relay, wiring harness, and all necessary installation hardware. Built-in protection guards against short circuit damage, and LED indicators provide clear feedback during calibration and activation. Its universal design makes it suitable for a wide range of EFI vehicles and nitrous setups, providing consistent and dependable activation every time.
