Worth the price

Mini x was easy to use. I have very little tuning experience so the ability to auto tune with the af2 made things really easy

Best ECU upgrade for Honda Grom (two thumbs up for 2 Step)

If you like to "set it and forget it" AND OR "tinker with it until you break something" this is the perfect ecu for you! You can setup autotune with the AF1 or AF2 module and forget this ecu exist while getting increased power and responsiveness. You can also mess with every setting aRacer has to offer and make your grom 1 of a kind! Out of the box I set my rev limiter lower (just so I can park it on rev limiter in a group of people and not hurt the engine) and I also set up launch control for 2 step! 10/10 would recommend over the Power Commander 5 because of the ease of use and YOU DO NOT NEED A PROFESSIONAL TUNER!

Couldn’t be happier

Switched from my CJR flash to this which I loved but I wanted more control and the option to tune for several fuels. Everything about it is great. Definitely not an exaggeration. Will always go this route moving forward in future bikes.

ARacer RCmini X is a Complete engine management system that allows you to make all adjustments via wifi to your smartphone/tablet. Pair this up with the correct fuel injector size and you could easily tune your engine to run.   Tuning could be done on a dyno (highly recommended) or safely on a backroad/street using a wideband o2 gauge and sensor with the autotune function.    Optional AF2 option is available and recommended to be used with the RCmini X to have the ECU Auto-Tune.
