Description
Lock and load your Polaris Pro R 4 cylinder and get ready for some serious kick! The Pro R is an awesome machine, but Polaris left a ton of room for improvement on the table. This simple kit is the best way to wake up your Pro R as it comes with our proven ECU flash. The ECU flash adds some amazing horsepower from low end to high end RPM and really gives your machine that “snap” you’re looking for. Our AA Stage 2 clutch kit compliments the tuning perfectly by more efficiently transferring power to the wheels and ridding yourself of the very lazy factory clutching setup and poor belt grip. We finish out the kit with our AA RZR Pro-R slip-on exhaust and it’s just what your machine needs! We set out to produce an exhaust that looks great, sounds great and has adjustable sound levels while producing the most power possible.
- Kit includes AA ECU flash for 2022-Up RZR Pro R 4 Cylinder Models **Requires ECU to be sent in for programming/unlocking unless choosing to purchase ECU outright** , AA Stage 2 Clutch Kit with primary clutch limiter and butter shift washers, and AA Stainless Center Exit Slip-On Exhaust.
- Works with all models including ones with Dynamix and/or EVAP models.
- Center exit exhaust with a chambered muffler. This design uses your OEM tip/spark arrestor making it a very quiet exhaust with the 3″ side dump closed with our optional 3″ Stealth Quiet Cap. Open up that 3″ side dump and let it scream when you want to!
- This center exit design with 3″ cutout allows for wild and mild sounds in seconds by bolting/unbolting the 3″ Stealth Quiet Cap, or the flip of a switch if you choose to upgrade to the electronic cutout.
- Looking for the best/most badass ECU tuning available for your RZR Pro R? AA’s performance tunes are now available to gain horsepower and torque. Through our advanced ECU tuning we are able to modify parameters correctly to gain you the power needed. We are highly experienced in tuning RZRs and this will show.
- The Pro R uses a new Bosch MG1 ECU. Currently no programmers like the PV3 are available that flash without first having the ECU unlocked. The HP Tuners Remote Tuning Device (RTD) allows the ECU to be flashed remotely at any time using the AA/HP Tuners RTD and your smartphone once the unlock process has been completed from AA. See HP Tuners RTD information below:
- HP Tuners Remote Tuning Device (RTD) option – Upgrades to HP Tuners RTD which includes the RTD, OBDII to Polaris Diagnostic Port cable, necessary credits to flash your ECU, one AA custom tune (more tunes optional), and ECU Unlock performed at the AA facility. Requires ECU to be sent in to be unlocked unless purchasing ECU outright. After the initial unlock, the ECU can now be flashed remotely at any time using the HP Tuners RTD and your smartphone. See links at bottom of product page for flashing your vehicle and data logging.
- Big horsepower gains depending on the level of tune/modifications (see tune descriptions below for more details)
- Much quicker throttle response and power delivery giving a whole new feel to the vehicle
- Throttle by wire limiters disabled
- Fan on/off at 185 degrees Fahrenheit (Stock is 190) which is just above the thermostat opening temp. The progressive fan also ramps up quicker to keep you running cooler than OEM.
- Speed limiter removed in low and high gears (Most will be able to run over 100 MPH!)
- Start in any gear with brake (RTD flash only)
- More throttle % in low gear and reverse
- Rev limit at a safe 9200 RPM (stock is 8650). Ideal peak RPM is 8200-8500 with the flash, but 9200 is for ramp up overshoot/top speed.
- AA’s wicked timing curve is safe for the fuel used, but we do a much better job of finding timing limits for ramp up/more torque. Many others simply focus on wide open throttle timing/fueling.
- AA’s modified fuel curve will still get decent mileage cruising, but is corrected over the factory lean AFR when needed.
- AA muffler is now available with an electronic cutout option to adjust sound on the fly without having to install or remove a quiet cap.
- Included Level 2 Tune: This tune is developed for a Pro R with our aftermarket exhaust on 91-93 octane. It has just a bit more timing and a bit more fuel over our Level 1. This tune adds +16 RWHP peak and a massive +19 RWHP at 38 MPH (This is gaining roughly +25 crank horsepower) putting you at roughly 250 crank horsepower with just a flash and exhaust! Our included Stage 2 clutch kit with this tune really helps the belt to grip and to help drive the extra power to the wheels. **Note: If you already have cams or are planning on upgrading to cams, cams can be run with our Level 2 tune if you already have it. However, hot starts are an issue with these cams and the Level 2 tune. Our Level 3 tune is suggested with these cams as it fixes hot starting, has better low end, and slight peak RPM fueling adjustments. For Level 3/cams We HIGHLY recommend upgrading to the HP Tuners RTD. While our tunes have been proven to work great with our shop vehicle and many others, some may have idle issues that need a revised tune. Higher lift camshafts are very finicky at idle. If you were to have idle issues, with the HP Tuners RTD we can deploy revised tunes quickly and easily whereas with a simple ECU flash that is not an option – you would need to send your ECU back for a reflash.
- Looking for race fuel tunes? We were also, but unfortunately we found no real power increase by adding octane. Certainly a little extra octane is never a bad thing to keep your ECU from pulling timing, but we tried various attempts to make more power with no results.
- If you’re unsure if your Pro-R is an EVAP model or not, check your Emissions Control sticker located on the front driver’s side frame rail above the master cylinder. See pictures for location.
- *** ECU MUST BE SENT IN FOR PROGRAMMING/UNLOCKING: Aftermarket Assassins, 2348 75th Ave, Osceola, WI 54020 *** (If selecting option to purchase ECU outright, disregard shipping notes as we will ship a new flashed/unlocked ECU to you)
- Customer is responsible for shipping the ECU to AA, a shipping label is not included in the price **Excludes Express Flash, which includes UPS Next Day Air label to ship ECU to AA
- Programming/unlocking turnaround will vary, but is normally 1-2 business days.
- Express ECU service for US main 48 states only. We’ll send you a Next Day Air UPS label, and ship your ECU ONLY back via Next Day. All other parts will be shipped ground unless otherwise specified/selected during order checkout. Keep in mind we cannot guarantee same day programming/unlocking or control UPS shipping times/delays. We will do everything possible to turn the ECU around as fast as possible.
- When the ECU arrives, we’ll read your stock file and keep a file folder for your stock/tune files. We’ll then flash with the correct AA tune.
- If you ever need to go back to the OEM tune, we charge $95 which includes shipping back to you (shipping back for lower 48 US only). Please contact us if you need to go back to your OEM tune. (This is only for the AA ECU bench flash, not the HP Tuners RTD or if you purchased an ECU outright)
- ENSURE you INSURE your ECU for $700. AA is not responsible for shipping delays or lost ECUs. While more expensive over Priority Mail or FedEx, UPS has been the most reliable carrier in our experience.
- Follow this link for instructions on locating/removing ecu
- The ECU is located behind the passenger (rear passenger if 4 seat) seat. Remove the top panel behind the seats, then remove the fabric panel to expose the ECU. Remove the Torx bolts and ECU connectors.
- Why AA tunes over others? We have been tuning UTV’s with CVT clutches for a long time, longer than almost anyone in our field going back to the 800 RZR. Tuning a CVT vehicle properly is not an easy task as you have so many variables at one time. We spend the time to wheel dyno(with actual UTV tires) correctly per modification, and have advanced ECU calibration and clutching knowledge to do so. Every change in horsepower can result in us changing clutching several times. We also develop most of our supporting mods so we know everything works correctly, and build parts to fit the vehicles needs. Lastly and honestly the most important; we then back up our results with real world data logging on local trails and our facility on 110 acres. It’s this combination that truly makes the difference and why AA normally has a faster vehicle with the same or less rated tune horsepower. We left nothing on the table on the Pro R bolt-on parts, if others claim more power/gains for the same mods use caution in believing it!
- If you have any other needs in these tunes, or any concerns; please e-mail!
- Stage 2 Clutch Kit includes: AA Recoil magnetic adjustable clutch weights, setup/installation sheet, primary spring, primary clutch limiter, secondary spring, butter shift washer/shim for increased spring preload and less spring harmonics
- Optional AA custom helix to upgrade your S2 clutch kit to a S3 clutch kit. This is highly suggested as it adds even more acceleration and helps transfer the power to the rear tires.
