AA Custom Tuned RTD w/ECU Unlock for 2024+ RZR 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 2024 and newer Polaris RZR 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

• AA was the first to flash the Polaris MG1 ECU
• Level 1 tune runs on a stock XP 1000 with 91 to 93 octane and adds 5 RWHP, putting it at roughly 120 crank HP
• Level 2 tune is built for an aftermarket exhaust on 91 to 93 octane and adds 7 RWHP peak and 9 RWHP at 30 MPH
• Throttle by wire and 2 foot limiters disabled, speed limiter removed in low and high gears, and start in any gear with the brake
• Rev limit set at 9200 RPM (stock is 8800) and fan on/off at 185/180°F (stock is 205/192)

Fits

• 2024 and newer Polaris RZR XP 1000, 2 seat and 4 seat
• 2026 and newer Polaris RZR XP 1000 S (72 inch wide)

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 to reach best peak RPM and power. AA suggests its clutch kit with both tune levels.
• AA tunes are developed for 91 octane unless stated otherwise. AA found no real power gain from race fuel on this platform.
