Polaris RZR 900 Hand Held ECU Tuner



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.

Boost Performance by Adding a Clutch Kit
To maximize performance gains, add a clutch kit! The improved engagement of a SuperATV clutch kit makes the most of the raised and removed limiters from your tune. You’ll see big gains in horsepower, torque, and top speed.

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 environment, such as temperature and altitude. For questions, please contact us to speak with a technical expert.
