The RZR Trail 900 is built to slip through 50-inch trails, and it's a blast in the tight stuff. Wouldn't it be nice if it had a little more power? The Dynojet Power Vision 3 comes with an ECU tune that will transform your Trail 900's performance. It adjusts engine timing for more horsepower and raises the speed and rev limiters to unlock higher speeds. It plugs directly into the standard diagnostic port and takes just a few minutes to install.
What You Get
- More horsepower from optimized engine timing.
- Higher speed and rev limiters for more room on open sections between the tight trails.
- Left-foot braking for brake-and-throttle control through rocky climbs, ruts and switchbacks.
- Faster limp mode so a fault doesn't turn into a long walk.
- Lower fan temps to help the engine stay cool on slow, technical days.
- Restore stock anytime using the saved factory file.
A Tuner That Works Double-Time
Power Vision 3 tuners have a bright, full-color screen that makes them easy to use, and you don't need to be an engineer to get the most out of one. Leave it plugged in while riding for a real-time readout of RPM, coolant temperature, wheel speed and more. It logs all that information so you can upload it to your computer and view it with the included Power Core tuning software. Once you've got the data, you can even use Power Core to build custom tunes. It's also a great help when you're trying to diagnose a problem.
Why Tune a Trail 900
Trail machines spend a lot of time at lower speeds, and that's where a crisper throttle and left-foot braking make the biggest difference. You can keep the engine in its power while scrubbing speed into a corner, then drive out harder. On the occasional open stretch, the raised limiters let the Trail 900 stretch its legs instead of hitting the factory cap.
Pairs Well With
A tune works best when the rest of the drivetrain is healthy. If your Trail 900 has a worn belt or tired clutch, address those first, then let the Power Vision 3 data screen help you keep an eye on engine temperature as you ride harder.

Please Note
The tuner pairs to your machine's unique ECU and can't be reset or used with another machine, so ECU tuners are non-returnable. Confirm you have a Trail 900 (not a Trail S 900) before ordering.
