FT550 Lite

The FT550LITE is perfect for projects that need more resources.

It has GearController, G force sensor and all the functions of the PowerFT line of ECUs.


Throttle Body Control (drive-by-wire)

Integrated GearController

Integrated BoostController

O2 Closed Loop

We are excited to announce the new FuelTech FT550LITE, which masterfully completes and expands the PowerFT line of ECUs. It delivers the powerful features of the FT550 without any software limitation and the right hardware for each project and budget. FuelTech offers amazing engine management systems for any type of project!


The FuelTech FT550LITE is the best ECU for projects that require more features, including GearController (power-shifts), built-in accelerometer (G-meter) and gyroscope; In addition to all PowerFT ECU line features such as sequential injection and ignition, O2 closed loop, active traction control, integrated BoostController, internal datalogger, progressive and PRO-Nitrous controls, electronic throttle control, drag racing features and more. It also features a sturdy and high-quality waterproof plastic case, automotive connectors with 52 pins, USB communication and two CAN Bus ports, 14 inputs and 24 outputs that are fully configurable.


The FT550LITE ECU uses the same FTManager software, with all the exact same features and functionalities, including the newest update that allows the user to update their fuel map by applying the O2 closed loop corrections that took place from a log file. The map files of all the PowerFT ECUs are compatible with each other, meaning that you can upgrade ECUs and keep the same tune you had already.
