AA Custom Tuned RTD w/ECU Unlock for 2025+ Polaris Ranger XP 1000

The Aftermarket Assassins Custom Tuned RTD pairs the HP Tuners Remote Tuning Device with an ECU unlock and an AA custom tune for the 2025 and newer Polaris Ranger XP 1000. The Bosch MG1 ECU in these machines cannot be flashed until it is unlocked, and once AA unlocks it you flash tunes, log engine data and clear codes from your phone.

Why it holds up

• Level 1 87 octane tune adds 3 RWHP, roughly 88 crank HP, and AA rates it 8 to 9 RWHP over stock with clutching
• Level 1 91 to 93 octane tune adds 5 RWHP, roughly 90 crank HP, and AA rates it 10 to 11 RWHP over stock with clutching
• Speed limiter removed in high gear, raised to 45 MPH in low (stock 29) and 30 MPH in reverse (stock 25)
• Throttle by wire limiters, seatbelt speed limiter and 2 foot limits disabled, start in any gear, and misfire detection desensitized to prevent false codes
• Rev limit set at 8800 RPM (stock is 8000) and fan on/off at 188/184°F (stock is 203/193)

Fits

• 2025 and newer Polaris Ranger XP 1000 (82HP base), 2 door and crew models
• 2026 and newer Ranger XP 1000 Cab models

In the box

• HP Tuners RTD
• OBDII to Polaris diagnostic port cable
• Credits to flash your ECU
• One AA custom tune (more tunes optional)
• ECU unlock performed at the AA facility

Good to know

• Your ECU must be sent to AA for the unlock unless you buy a new ECU outright. After the unlock, the ECU can be flashed at any time with the RTD and your smartphone.
• Standard unlock averages 4 to 10 business days. Instructions for shipping the ECU arrive within 1 business day of purchase, and the work takes 1 to 2 business days once the ECU reaches AA. Shipping time to and from AA in Wisconsin varies by location.
• Express unlock averages 2 to 3 business days and is for the continental US 48 states only. A UPS Next Day Air label and instructions are provided, and the ECU returns by next day shipping.
• Buying a new ECU outright lets you keep your current ECU as a spare. List your VIN in the checkout notes.
• Clutching is highly suggested, since OEM clutching falls short of peak RPM for this motor and tune. AA suggests its S3 clutch kit.
• Level 1 tunes run fine with an aftermarket exhaust, but Level 2 is the better match for one.
