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

PRODUCTS NEEDED

To use these features, you will need to install several components in addition to you FuelTech ECU. These include:

👉 PS-150 Pressure Sensor

HOW IT WORKS

When the ECU reads wheel speed 0 MPH and driveshaft at 0 RPM, the multifunction button will act as line lock button.

1. Open the FTMANAGER software, go to Inputs and configure your multifunction button and your 2-step button.

2. Next, go to Map Options and enable Brake Line Lock Control, Staging Control and Wastegate Boost Control.
