2012-2022 Polaris RZR 900 ECU Power Flash


Evolution Powersports has released its lethal Polaris RZR 900 Programming.

Huge horsepower gains have been realized through timing, fueling, torque limit modifications, rev limiters & speed limiters. The biggest performance barrier is the OEM programming limits throttle opening and therefore maximum power of this engine. We allow 100% throttle in addition to the other parameters listed to extract 15 Wheel Horsepower - with just programming on a stock vehicle! More power is available with an intake and/or exhaust!

We also build additional safety into our tune by lowering the fan on temperature by 20 deg F. The OEM fan on temperature is is too high (well over 200 deg F). In addition the fan on/off temperatures can be set for each customer depending upon where they live and the conditions typically ridden in. Other great features are added and/or changed to enhance the drivability and fun factor of the vehicle.

Evolution Powersports has vast knowledge of the Polaris Bosch ECU from our work in the automotive world. We have brought this expertise to the SXS market to extract the most performance from the Polaris Pro Star 900 engine as possible. For vehicles with Turf Mode and/or ADC, these features are preserved. Please ship your ECU to our Somerset WI location or you may choose "With New Polaris ECU" checkbox. You can also have your ECUs programmed by one of our Flashing Dealers (see Dealers section for a list of dealers with flash capability)2015+ models gain 15+ wheel horsepower with stock intake and stock exhaust - no other modifications necessary! Older XP models gain 5+ wheel horsepower. Even larger gains with exhaust and/or intake!

• Rev Limiters raised to 9000 for both high and low gear
• Improved throttle response in all modes (E-Gas Settings Improved)
• 100% Throttle in both high and low gear
• Improved ignition timing advance optimized for 91 Octane for maximum power
• Fueling adjusted for aftermarket components (intakes, exhausts and cat deletes) for optimal Air/Fuel Ratios
• No need to run a "piggyback" fuel controller with our reflash for most bolt on mods (You are responsible to make sure your mods are compatible with our programming - All EVO and most other aftermarket companies' exhausts are compatible with our programming as well as all EVO intakes)
• Torque Limiters removed ("Shaft Saver delete") for a much more responsive and fun vehicle
• Cooling fan on temperature is lowered by 20 Deg F, but can be set to whatever temperature the customer wants
• Vmax Raised (Speed Limiter Raised)Evolution Powersports always makes it easy to upgrade your tune in the future - you only pay for the difference in tune cost plus shipping




The factory ECU calibration limits your fun. Limits speed, limits revs and limits TQ - all the things that limit performance and enjoyability with your machine. With an EVP Power Flash your engine is recalibrated and its full power potential is unleashed! Your engine will deliver more power, rev higher, respond quicker and accelerate faster for improved performance and overall drivability.




Our state-of-the-art, climate-controlled dyno lab allows us to precisely measure power & torque output of our Power Flashes during our development process & prior to our real-world testing regimen.



Top racers & race teams choose EVP Power Flashes – they know that our tunes will give them the power and safety they need to get to the podium.



We utilize the same ECU calibration tools as the OE manufacturers which allows access to the entire ECU, not just simple tune road maps other companies are limited to, for ultimate control, modification, and upgrade possibilities.



Our motto since the beginning has been “We test where you ride” and we continue to test & prove our software in the most grueling off-road conditions possible to ensure we deliver the most refined, powerful & relentlessly tested ECU Power Flash possible.


2015+ models gain 15+ wheel horsepower with stock intake and exhaust. Older XP models gain 5+ wheel horsepower, larger gains with aftermarket exhaust and intake.

Rev limiters raised to 9000 for both high and low gear.

100% throttle opened.

Dramatically Lowered Coolant Temperatures by Manipulating the Fan On/Off Temperatures (EVP was the first to introduce this technology)

Improved ignition timing advance optimized for 91 octane.

Improved throttle response in all modes (E-Gas settings improved).

Vmax raised (speed limiter)

Torque limiters removed "Shaft Saver delete" for a much more responsive and fun vehicle.

No Piggyback Fuel Controllers to Mess With

*Custom Rev Limits available upon request



When we develop our tunes, we engineer tunes we want to ride and race with. Insatiable when it comes to testing, our process starts out with over 200+ dyno runs in our state-of-the-art, climate-controlled Dyno Room.
We then field test on trails, desert, dunes and high altitude for driveability and long-term durability. We also run in the 110+ degree California weather to ensure performance at extreme temperatures.
After the rigorous field-testing route is completed, they are further proven and refined on the track through our EVP Sponsored Racers.


We don't throw around terms like industry leading without the winning proof. We own a constantly evolving fleet of cars which allows us to do parallel development on stock turbo consumer tunes and race-prepped vehicles to develop only the best engineered and designed products and software. Our in-house race team, EVP Racing, not only competes with our own shop-built cars (ever heard of the Desert Storm & Hustler?) which consistently bring home wins, but the team also works as Race Support to many top desert, short course, cross country, rock and mud racers in the industry such Kyle Chaney, Dustin Jones, Matt Burroughs, Marc Burnett, Lonestar Racing, Scottie Lawrence, Sara Price, Brice Menzies, Jake Carver, Paul Wolff and many others. The top teams in a vast range of race series use EVP tunes & products to help get them to the podium in BITD, SCORE, ULTRA4, TexPlex, WORCS, SXS Sports, AXCC, CHAMP, Pro Rock and many other race series with count-less podiums.









A Power Flash is the act of flashing your vehicle's ECU (Electronic Control Unit) with an EVP engineered tune.

Essentially, our tunes (or 'software') gets flashed (or 'installed') on your vehicle’s factory computer. The software controls the way the engine operates. Unlike other tunes you'll find on the market,  an EVP tune is tailored for the specific components installed on your machine. This is among the first modifications you should consider for your vehicles as they deliver the most impactful difference you can feel and measure for the money.

CodeShooter is the most innovative app-based ECU tuning device for powersports vehicles. The most intuitive and easy-to-use wireless flashing tool on the market, you now have the power to flash your vehicle’s ECU/Dash*, read and reset trouble codes, as well as monitor live critical engine data all from your smartphone!
