Why We Make It

We put performance in the palm of your hand with a SuperATV Hand Held ECU Tuner for the Polaris RZR 900. There’s never been an easier way to improve horsepower, torque, max speed, throttle response, rev limiters, and more. Just connect our tuner to your RZR and press a few buttons — Flash, Gas, and Go!

Industry Leading R&D

Our tuner gives you one-of-a-kind tunes that squeeze out every ounce of performance from your UTV. When it comes to performance, we know what we’re talking about. We have spent hundreds of hours perfecting our tunes and testing them on our in-house dyno and out on the trail. We did all that work so you don’t have to — all you have to do is plug it in and ride.

All our tunes are dyno tested on 100% stock machine unless noted. Factory and aftermarket clutching and ECUs may behave differently in extreme changes to the environment, such as temperature and altitude. For questions, please contact us to speak with a technical expert.
