AA ECU flash for 2025 Polaris Ranger XP1000 (82hp Base) Models **Requires ECU to be sent in for programming**
Works with all models 3 or 6 Seat
Looking for the best/most badass ECU tuning available for your '25 Ranger XP 1000? 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 UTV's and this will show.
The 2025 Ranger XP 1000 uses a new Bosch MG1 ECU. Currently the only available option is to send your ECU in to us for a flash. We also have a few flash devices available like the MG1 PV3 & HP Tuners RTD, but they also require the ECU to be sent to us for an unlock. Most find it easier to simply send in your ECU for a flash unless needing the ability to have multiple tunes/switch tunes on your own.
Big horsepower gains depending on the level of tune/modifications (see below tune level descriptions for more details)
Much quicker throttle response and power delivery giving a whole new feel to the vehicle
Throttle by wire limiters disabled
Seatbelt speed limiter removed if you choose
Misfire detection disabled if you choose. This is a safety feature built into the ECU to shut fuel off for that cylinder if a misfire is detected. Oftentimes, this system gives a false misfire and puts you into limp mode. This is completely your choice to keep or disable.
Start in any gear (factory will only start in park)
Fan on/off at 188/184 (Stock is 203/193) degrees Fahrenheit which is just above the thermostat opening temp. We also ramp up fan speed quicker than OEM (PWM fan speed increases as engine temps increase)
Speed limiter removed in low and high gears (Speed limit in high is 62mph in high and 29 low for crew models)
More throttle % in low gear and reverse (stock limits your throttle for torque limitation)
Rev limit at a safe 8800 RPM (stock is 8000). Ideal peak RPM @ 55mph in a wide open throttle run is 7200-7600 with the flash, but 8800 is for ramp up overshoot/top speed.
Clutching is highly suggested to achieve best peak RPM and best power output as the OEM clutching will fall short of peak RPM for this motor/tune.
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 good mileage cruising, but is corrected over the factory lean AFR when needed most on higher throttle inputs.
Level 1: This tune can be run on a bone stock Ranger on 91-93 octane fuel. This tune adds +3-4 RWHP (5-6 crank HP) putting you at roughly 120 crank horsepower with just a flash! Add clutching and you are a huge 8-9rwhp above OEM! We would highly suggest our S3 clutch kit with this tune as it loads the Ranger better down low for torque, allows peak RPM to ramp up faster in the mid/high end, and has slightly higher peak RPM for better peak power. This tune can be run with an aftermarket exhaust without any issue, 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 Ranger with aftermarket exhaust on 91-93 octane. This tune adds +7-8 RWHP. Due to how these motors/tuning works, this tune should work with about any aftermarket exhaust, but was tested and designed with our AA Dual Suppressor Slip-On Exhaust.
If you're unsure if your Ranger 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. Normally the ECU also has a sticker on it giving you/us this information.
The drop down also asks if your Ranger has HVAC(air/heat) or the standard model without
We will follow up with instructions on how to locate, remove, and send your ECU.

Customer is responsible for shipping to AA, a shipping label is not included in the price (Unless express flash is selected)
Programming turnaround may vary, but is normally 1-2 days.
Express ECU service for US main 48 states only. We'll send you a next day UPS label, and ship your ECU ONLY back via next day. All other pats 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.
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.
MAKE SURE you insure your ECU for $700. AA is not responsible for shipping delays or lost ECU's. While more expensive over Priority Mail or Fedex, UPS has been the most reliable carrier in our experience.
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 Ranger 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!
Oh... and get ready for your Ranger to flat out rip!
