Product Information

SKU: 118-1004-SSS

AA ECU Flash for 2025 Polaris Ranger XP 1000 (82HP Base) 2 Door and Crew Models delivers unmatched performance tuning for riders who demand more horsepower, torque, and throttle precision. Designed specifically for the latest Bosch MG1 ECU, this advanced reflash unlocks the full potential of your machine by optimizing timing, fueling, and throttle parameters. ECU must be sent in for programming, ensuring a professional calibration tailored to your model and modifications.

Through years of experience tuning UTVs, Aftermarket Assassins has developed one of the most refined ECU calibrations in the industry. The result is a powerful and responsive ride that eliminates throttle-by-wire delays, disables restrictive limiters, and provides a smoother, more controlled powerband. Whether you use your Ranger XP 1000 for work or play, this tune transforms drivability while maintaining safe operating conditions and reliability.

  • Gain up to 12 additional horsepower depending on tune level and supporting modifications.
  • Improved throttle response and faster acceleration for a noticeably more aggressive feel.
  • Removes seatbelt and speed limiters, enabling higher speeds in both high and low gear.
  • Revised fan temperature settings for improved cooling and engine longevity.
  • Allows starting in any gear and disables two-foot braking limits for better control.
  • Rev limiter increased to a safe 8800 RPM to maximize top-end performance.
  • Optimized fuel and timing maps for cooler exhaust temps and improved efficiency.
  • Compatible with both stock and aftermarket exhaust systems.

Choose from multiple tune levels to match your setup and fuel type. Level 1 tunes are ideal for stock configurations, while Level 2 tunes are designed for machines equipped with aftermarket exhaust systems. Both options are available for 87+ and 91–93 octane fuels, providing flexibility and performance gains based on your riding style.

To achieve the best results, pairing your ECU flash with an AA S3 clutch kit is highly recommended. Proper clutching helps your Ranger reach peak RPM faster, enhances low-end torque, and allows the motor to maintain consistent power under load. Every tune is tested on a wheel dyno using real UTV tires and validated with extensive trail data logging to ensure accuracy and durability under real-world conditions.

Each ECU flash includes professional programming by Aftermarket Assassins technicians. Standard turnaround is typically 1–2 business days once your ECU is received. Express ECU service is available for customers in the continental U.S., providing next-day shipping both ways for minimal downtime. For maximum security, it is recommended to insure your ECU for $700 during shipment.

Aftermarket Assassins’ dedication to precision tuning, in-depth testing, and real-world performance makes this AA ECU Flash for the 2025 Polaris Ranger XP 1000 the ultimate upgrade for riders seeking reliable horsepower gains and superior throttle performance. Elevate your Ranger’s capability, unleash its hidden power, and experience a completely new level of off-road performance with confidence.
