Aftermarket Assassins '24+ Polaris RZR XP 1000 Custom Tuned RTD w/ ECU Unlock

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 XP1K bolt-on parts, if others claim more power/gains for the same mods use caution in believing it.

Standard Unlock Process (Average 4-10 business days): Within 1 business day after purchase, we will send you instructions on sending in your ECU. You will be responsible for shipping the ECU to AA. Once at it arrives at AA, the ECU will take 1-2 business days to complete. Your ECU will then be sent back via standard/your selection of order shipping. Turnaround time greatly varies on your location and how long shipping takes to/from AA in Wisconsin.
Express Unlock Process (Average 2-3 business days): **For the continental US 48 states ONLY** We will send you a UPS Next Day Air label and instructions. You will need to attach this label to your own ECU package, then give the package to your local UPS drop-off location. Once at AA, the ECU will take 1-2 business days to complete. The ECU will then be sent back to you via Next Day shipping. When the ECU arrives, we'll read your stock file and keep a file folder for your stock/tune files. We'll then flash it with the unlock file so it's ready to use with the RTD. All other parts on the express flash order will be shipped ground unless otherwise specified/selected during order checkout. Keep in mind we cannot guarantee same day programming or control UPS shipping times/delays. We will do everything possible to turn the ECU around as fast as possible.

Looking for the best/most badass ECU tuning available for your 2024+ RZR XP 1000? AA's performance tunes are readily 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 UTV's and this will show. We were the first to flash the Polaris MG1 ECU, and spent a huge amount of time in R&D to develop the most powerful ECU calibrations (tunes) possible.
The 2024+ RZR XP 1000 uses a new Bosch MG1 ECU. Currently no programmers are available that flash without first having the ECU unlocked. The HP Tuners RTD allows the ECU to be flashed remotely at any time once the unlock process has been completed from AA.

Level 1: This tune can be run on a bone stock XP1K on 91-93 octane fuel. This tune adds +5 RWHP (6 crank HP) putting you at roughly 120 crank horsepower with just a flash! We would highly suggest our clutch kit with this tune to help with belt grip and gain additional low to mid range power. This tune can be run with an aftermarket exhaust, but our Level 2 tune is the best option for aftermarket exhaust as it's slightly richer for more power and less heat.

Level 2: This tune is developed for an XP1K with aftermarket exhaust on 91-93 octane. It has just a bit more timing and a bit more fuel over Level 1. This tune adds +7 RWHP peak and a massive +9 RWHP at 30 MPH (This is gaining roughly +10-11 crank horsepower) putting you at roughly 125 crank horsepower with just a flash and exhaust! We would highly suggest our clutch kit with this tune to help with belt grip and to help drive the extra power to the wheels. Due to how these motors/tuning works, this tune should work with about any aftermarket exhaust, but was tested and designed with our AA slip-on exhaust.
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.

Features:

• After the initial unlock, the ECU can now be flashed at any time using the AA/HP Tuners RTD and your smartphone.
• Price includes HP Tuners 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.
• Allows you to flash the ECU, log engine parameters and view/erase trouble codes from your phone!
• 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
• 2 Foot Limiters Disabled
• Fan on/off at 185/180 degrees Fahrenheit (Stock is 205/192) which is just above the thermostat opening temp.
• Speed limiter removed in low and high gears
• Start in any gear with brake
• More throttle % in low gear and reverse as the factory limits these gears to not open the throttle fully
• Rev limit at a safe 9200 RPM (stock is 8800). Ideal peak RPM @ 55 MPH in a wide open throttle run is 8400-8600 with the flash, but 9200 is for ramp up overshoot/top speed.
• Clutching is highly suggested to achieve best peak RPM and best power output
• AA's wicked timing curve is safe for the fuel octane recommended, 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 tunes are developed for 91 octane unless specified otherwise.
• AA's modified fuel curve will still get good mileage cruising, but is corrected over the factory lean AFR when needed most on higher throttle inputs.
• 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 based on engine knock, but we tried various attempts to make more power with no significant results.
• If you're unsure if your XP1K is an EVAP model or not, check your Emissions Control sticker located on the front driver's side frame rail above the shock. 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
• When the ECU arrives, we'll read your stock file and keep a file folder for your stock/tune files. We'll then flash the HPT unlock file into the vehicle.
• 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.
• We will follow up with instructions on how to locate, remove, and send your ECU.
