The React Throttle Optimizer has five different settings that are preprogrammed to enhance the settings of your throttle. The REACT will help you to get superior performance from your throttle. The REACT Custom Tuning Software gives you the ability to adjust the settings for each of the REACT’s modes for the ultimate customization experience.
The REACT has included safety precautions to guarantee your throttle never reacts differently from what you want.

If the REACT locates an error, it will enter a bypass mode that removes its circuitry from the path to the ECU and shows an error signal on the control unit.
