Testing It Out: The Dynojet Power Vision CX For Polaris RZR

We got our first look at the Dynojet Power Vision CX tuner for the Polaris RZR Turbo when we helped Warfighter Made on a custom UTV build for a deserving wounded veteran – Navy SEAL Elliot Miller. Miller’s 2017 Polaris RZR XP 4 Turbo got a whole host of upgrades, some as a result of the boost in power provided by the Power Vision CX. After the newfound power, Super ATV Rhino 2.0 axles were installed to provide some added strength.

The front view is enhanced with Assault Industries mirrors, and grill.

The Dynojet Power Vision CX tuner allows users to flash performance tunes by simply plugging into the OEM diagnostic connector. There is no need to remove the ECU, send it out, and then wait for it to return. Once plugged into the OBD port and programmed, the weather-resistant unit displays vehicle data in real time. It’s very simple to mount, and the high contrast display is viewable in direct sunlight.

The Dynojet Power Vision CX tuner allows comprehensive tuning adjustments that boost performance across the board. Fuel delivery gets revised for maximum power and torque, and spark timing is optimized for 91-93 octane fuel. Both the speed limit and RPM limits are increased in high and low gears. Revised drive-by-wire throttle profiles are also configured for high and low gears, and torque-limiting functions are either reduced or completely eliminated. Left foot brake mode is enabled while still retaining ADC and Turf mode where applicable. The Power Vision CX tuner does it all safely with Boost control for Turbo models, and programming to turn the cooling fan on at lower temperatures. Whether one has a stock or modified exhaust, intake modifications, free-flowing injectors, or additional boost, there is a long list of available tunes tailored to either stock or modified engines.

The unit plugs directly into the diagnostic port. We only drilled a single hole in the dash for the wiring.

To better explain the RZR’s modifications, Warfighter Made gave us the lowdown. The team installed MSA 15-inch M31 LOK2 beadlock wheels, wrapped in BF Goodrich T/A KO2s. UTV Wiring sent their awesome dual battery system, hooked to a pair of Odyssey batteries; this system guarantees that Miller will always have battery power in reserve.

Elliot’s 2017 XP 4 Turbo was outfitted with a Gibson single out replacement muffler. After plugging the Power Vision CX in and programming the computer, the dyno recorded an additional 8hp to the rear wheels (the squiggles at the end were from the rev limiter). There is no easier way to get such detailed engine management and boost in horsepower.

Baja Designs donated a 30-inch light bar for the roof and LED pods reside in the Dirt Engineered front bumper. Dirt Engineered also supplied a set of nerf bars, color-matched perfectly with the rest of the car. Assault Industries supplied tie and radius rods, mirrors, a grille, and their quick-release fire extinguisher just in case. Sandcraft RCR donated their entire “Complete Drivetrain Solution” package, including the third-generation carrier bearing, upgraded prop shafts, and engine mounts. Still, adding all of these features also adds weight to the RZR. The Dynojet Power Vision CX tuner’s engine controls and additional horsepower is just the ticket, providing additional snappy throttle response that completes the package.

If you have a stock or modified exhaust, intake modifications, free flowing injectors, or are running additional boost, Power Vision CX has a long list of available tunes tailored to either stock or modified engines.

Warfighter Made wanted to make sure that Elliot had a machine worthy of putting a smile on his face, and they succeeded with some help from Dynojet. We encourage you to check out more from these ventures by visiting them online.
