Bought the mini x and af2 with high expectations and they were all met and exceeded. Highly recommend it to anyone looking to tune their grom for a little extra power

Sean Whitelock
ARacer Mini X (2022 Monkey)

ARacer is by far the easiest way to tune these bikes, expensive, yes, But worth if if you like changing things, I’m always trying new things with these bikes, Have a mini 5 in my grom, Always trying different bore kits, cams, intakes and exhausts, so have auto tune is pretty benificial! Dhm had it to my door in Canada in under 24h, unreal!

Fast shipping and easy purchasing options

The unit came within a week. Shipping is fast with DHMotoring. I like the ability to use Afterpay on the high dollar items.

Aracer mini x its a premium product it works well does what it says on the can. Seems expensive at first but if you mod quite a bit being so flexable it quickly pays for itself. Bike is running well.

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.
