aRacer RC Super 2 ECU: (2019+ CRF110)

The aRacer RC Super 2 for the CRF110F is now available! Time and time again, aRacer has proven to provide riders with game changing products that guarantee an increase to their overall bikes performance. This RC Super 2 has new added features including wireless monitoring that is accessible through the aRacer mobile app. With this new feature, you're able to stream any data from your bike to your phone in real-time.

ARacer RC Super 2 is a complete engine management system that allows you to make all adjustments via a laptop. Tuning could be done on a dyno (highly recommended) or safely on a track or even a backroad/street using a wideband o2 gauge and sensor with the autotune function like the AF1/AF2 that we sell separately. 

The aRacers mobile app allows all complete monitoring your bike on the go. Allowing for features like Data Log, where you can now log and view your ride or race to make proper adjustments via your laptop. aRacer has made it easy to adjust and view your engine details. This does require the aRacer iLink Calibration Cable. The RC Super 2 has made several improvements including higher accuracy and faster computing power. This is key to providing the most detailed information for adjustment and easier to obtain a stronger AFR. It also works with their all-new knock sensor! This will provide more tuning capabilities with timing. This is the only model that can currently run that sensor. If you have any questions please contact us.

In order to use any additional modules aRacer 1 to 4 Cable is required.

Now comes with bLink with improved Bluetooth Phone connectivity.
