WARNING: Cancer and Reproductive Harm - Introducing the all-new aRacer RC Mini X for the 2021 Honda CRF300L, a standalone ECU featuring advanced capabilities including wireless monitoring and tuning. With the new aRacer X-Tune app, you can stream real-time data from your bike directly to your phone!
The aRacer X-Tune app provides complete calibration and adjustability for your bike on the go. Features include Data Log, allowing you to log and review your ride or race and make precise adjustments to the Engine Calibration section. You can adjust fuel settings, spark settings, engine settings, and vehicle settings in real-time. Best of all, you can save and share your custom tunes.
This is a standalone ECU, not a piggyback like Power Commander. For optimal performance, we recommend the aRacer AF2 Wideband Autotuner Module for automatic air/fuel tuning.
