This is a state of the art GP1 Racing Strain Knob that we’ve used for years on many of our own drag cars. Simply install this shift knob then wire in the power/ground/signal wires to the ECU, and set up the input in your EMS system to trigger an ignition cut for easy, seamless full-throttle clutchless upshifting!

This system works great for either rod or cable-actuated shifters such as your common Honda/Acura B-Series or K-Series cars. We use the 2.5V Reference Amplifier Module option as most standalone EMS will easily accept a 0-5V trigger range.

 2.5v Resting Voltage for Motec, AEM, Haltech, Fuel Tech

 All Strain Knobs are bench tested before shipping out to customers.
