Your RZR 900 is keeping a secret: there's hidden power and performance locked behind the factory calibration. The Dynojet Power Vision 3 unlocks it. Its preloaded ECU tune raises the speed and rev limiters for higher top speeds and adjusts engine timing to squeeze out extra horsepower. You get more speed and more power without ever opening a toolbox, since the tuner plugs right into the standard diagnostic port.
What the Tune Does
- Raised speed and rev limiters so the 900 keeps pulling on long straights.
- Timing adjustments for extra horsepower and quicker throttle response.
- Left-foot braking. Use brake and throttle together without a power cut. On a sport machine that means better control through corners, jumps and rocky climbs.
- Faster limp mode so you can still ride back to the trailer if a sensor faults.
- Lower fan temps to keep the engine cooler in slow, technical sections and summer heat.
- Fully reversible, with your stock calibration stored on the tuner.
Easy to Use and Easy to Read
Power Vision 3 tuners are simple. They have a bright, full-color screen you can actually read, and once you're set up it takes just a couple of minutes to install. Leave it plugged in for a live readout of RPM, coolant temperature, wheel speed and more. That data can be uploaded to your computer, where you can view it and tweak your tunes using the included Power Core tuning software. The logged data is also handy when you're trying to diagnose a tricky problem.
Where You'll Feel It
The 900-class RZR is light and nimble, and a sharper throttle makes it even more fun. You'll notice the difference in how hard it drives out of tight corners and up loose hills, and the higher limiters let you carry speed on fast fire roads. If you've added a clutch kit, exhaust or bigger tires, Power Core lets you adjust the tune to match.
Two-Seat or Four-Seat
The same tune covers the two-seat RZR 900 and S 900 as well as the four-seat RZR 4 900 and S4 900 in the listed years. Four-seaters carry more weight, so they tend to benefit even more from the added pull, especially with a full load of riders and gear.

Returns
Each Power Vision 3 pairs to the first ECU it flashes and can't be reset or used with another machine. Because of that, ECU tuners are non-returnable. Please check the chart carefully before ordering.
