Aftermarket Assassins '24+ Polaris RZR XP 1000 Stage 1 Lock & Load Kit
Lock and load your 2024+ Polaris RZR XP 1000 and get ready for some serious kick! The 2024+ RZR XP 1000 is a fun machine, but Polaris left room for improvement on the table. This simple kit is the best way to wake up your XP1K as it comes with our proven ECU flash. The ECU flash adds some amazing horsepower from low end to high end RPM and really gives your machine that "snap" you're looking for. Our AA Stage 3 clutch kit compliments the tuning perfectly by more efficiently transferring power to the wheels and ridding yourself of the very lazy factory clutching setup and poor belt grip.
The 2024+ RZR XP 1000 uses a highly secure Bosch MG1 ECU. To use a programmer on this ECU, you must first send your ECU in for a specific unlock process (unique to that device). Besides our standard bench flash, we have two programmer options which are the AA/Dynojet MG1 PV3 or the AA/HP Tuners RTD
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 decent 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 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.
The 2024+ XP 1000 is clutched very odd from the factory. The vehicle winds out RPM right from the gate and does not transfer any torque until you hit peak RPM. This is somewhat of a race setup, but really all around it does not work well. Our kit helps combat this with our helix specifically designed for this model, along with our weights and springs that are all key components in transferring power to the rear tire efficiently. This is shown on the dyno and felt in real world driving (butt dyno). The clutch kit also adds huge belt grip and is especially needed when going to larger tires. The Performance helix gains the most acceleration, while the High Load helix is a little more than stock but less aggressive for excessively heavy/large tires, crawling, or mud riding.
Features:
- 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
- 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
- Seatbelt Limiter Removed
- 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 is 8400-8600 with the flash, but 9200 is for ramp up overshoot/top speed.
- 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
Fitment:
- Fits All 2024+ RZR XP 1000 & 2026+ RZR XP1000 S (72" Wide) Models
