August 29, 2024

Step-by-step instructions on how to configure the Multifunction Button on your FuelTech ECU. In this guide, we’ll show you how to set up the button to perform specific functions: acting as a line lock when wheel speed is 0 MPH and driveshaft RPM is at 0, serving as a staging button when the ECU is in 2-step mode, and functioning as the boost + scramble button when using the wastegate boost control feature under all other conditions. Follow our detailed instructions to ensure your Multifunction Button is optimized for every scenario on the track
