ECU Chip Tuning Module Racedynamics FuelX Lite Yamaha XSR 125 2020-2023

The FuelX Lite Autotune is an electronic add-on module for optimizing fuel injection on the Yamaha XSR 125. Especially with standard 125cc engines, the air-fuel mixture is often very lean, which can result in rough throttle response, uneven engine running, or increased thermal stress.

The FuelX Lite intervenes directly in the injection control and automatically adjusts the mixture. This makes the engine run more smoothly, respond more cleanly to throttle commands, and feel more harmonious overall. Driveability is noticeably improved, especially in the lower and middle speed ranges, which is just as beneficial in city traffic as it is when driving at speed on country roads.

In combination with an open air filter or an aftermarket exhaust system, the FuelX Lite ensures a balanced setup without the need for manual tuning. Installation is plug-and-play and completely reversible. Once installed, the system works independently and continuously adapts to driving conditions and existing modifications.
