  • AA ECU flash for 2024 RZR XP 1000 Models  **Requires ECU to be sent in for programming**
  • Works with all models
  • Looking for the best/most badass ECU tuning available for your 2024 RZR 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 RZR's and this will show.
  • The 2024 RZR XP 1000 uses a new Bosch MG1 ECU.  Currently no programmers like the PV3 are available and no ETA, so sending your ECU in for a bench flash is the only way to get a great tune.
  • Big horsepower gains depending on the level of tune/modifications (see below tune descriptions 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
  • More throttle % in low gear and reverse (Stock limits your throttle for torque limitation)
  • Rev limit at a safe 9200 RPM (stock is 8800).  Ideal peak RPM @ 55 MPH in a wide open throttle run is 8400-8600 with the flash, but 9200 is for ramp up overshoot/top speed.
  • Clutching is highly suggested to achieve best peak RPM and best power output
  • 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 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.  
  • Looking for race fuel tunes?  Let us know and we can help you.
  • If you're unsure if your XP1K 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.
  • We will follow up with instructions on how to locate, remove, and send your ECU.
  • *** ECU MUST BE SENT IN FOR PROGRAMMING:  Aftermarket Assassins, 2348 75th Ave, Osceola, WI 54020  ***
  • Customer is responsible for shipping to AA, a shipping label is not included in the price (Unless express flash is selected)
  • Programming turnaround will 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 XP1K 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 RZR to flat out rip!

Perfect protection for daily use
Size: 6.76 Fl Oz (Pack of 1), Style: Lotion (SPF 50)
This is my go-to sunscreen for my daily use. I have stuck to a strict skin care routine and at the end, it’s extremely important to have a sunscreen to seal the deal. And this does just that. It doesn’t leave that nasty white streaks from the sunscreen and goes on very nicely. Out of my months of using this I have never been uncomfortable with it and the smell is very refreshing unlike other brands of sunscreen. Most importantly, this doesn’t feel greasy or overly slick. Perfect balance.

Great
Size: 6.76 Fl Oz (Pack of 1), Style: Lotion (SPF 50)
While it is a bit thick, that can be great for sweaty summer activities (also it's purpose)! It does not leave a white cast (on me, though I am pale, I have experienced this with other sunscreens) and smells okay, not great but like a sunscreen would be expected to. It's not a super strong scent and does not burn my eyes. Sits good under my makeup as well.

Great protection and not greasy.
Size: 6.76 Fl Oz (Pack of 1), Style: Lotion (SPF 50)
This sunscreen is great. It is not greasy and protects for a long time. I have had a few battles with skin cancer, but feel confident that this stuff will protect me. Yesterday was hot and sunny and my skin was still protected after 4 hours on the golf course.

Instant relief and moisturized skin well!
Size: 3 Ounce (Pack of 1), Style: Cool Down Lotion
We used the Sun Bum Cool Down Aloe Vera Lotion after getting a little too much sun on vacation, and it worked so well. It gave instant cooling relief without any sticky or greasy feeling. The lotion absorbed quickly and actually soothed the burn instead of just sitting on top of the skin like some aloe gels do. The smell is light and tropical—really pleasant and not overpowering. After applying it a couple of times, our skin felt way less hot and tight, and it definitely helped prevent peeling. We’ll absolutely be bringing this with us on every beach trip from now on! Highly recommend if you’re looking for a sunburn solution that actually works and feels good to use.

Sun Bum Cool Down After Sun Lotion
Size: 8 Ounce (Pack of 1), Style: Cool Down Lotion
I would give this more stars if I could! As someone who spends as much time as possible soaking up the sun during the summer, I’ve found a true gem in Sun Bum’s Cool Down After Sun Lotion. This product has become my go-to for post-sun care, and it’s easy to see why—it’s like gold for sun-exposed skin! With its fantastic tropical scent, skin-loving formula, and high ratings on the Yuka app for its all-natural ingredients, this lotion is a standout. Here’s a detailed look at why I highly recommend it for anyone who loves summer adventures. Ingredients and Yuka Rating One of the standout features of Sun Bum’s Cool Down After Sun Lotion is its commitment to clean, natural ingredients, which has earned it excellent reviews on the Yuka app. According to the product description, it’s formulated with soothing aloe vera, vitamin E, and coconut oil, all of which work together to hydrate and nourish sun-exposed skin. These ingredients are free from harmful chemicals like parabens, sulfates, and dyes, making it a safe choice for those prioritizing non-toxic skincare. The Yuka app, known for analyzing product safety, rates this lotion highly for its clean, natural composition, which aligns perfectly with my preference for products that are good for both my skin and the environment. This clean formula gives me peace of mind, knowing I’m not applying anything harsh after a long day in the sun. Scent and Sensory Experience The scent of this lotion is nothing short of phenomenal—it truly smells like summer in a bottle! The tropical, coconut-adjacent fragrance is light and refreshing, evoking the feeling of a beach vacation. Unlike some overpowering or artificial-smelling products, Sun Bum’s scent is gentle yet nostalgic, making the application process a delight. It’s not just about function; this lotion elevates the entire post-sun care routine with its inviting aroma, which lingers subtly on the skin without being overwhelming. Performance and Skin Benefits When it comes to performance, Sun Bum Cool Down After Sun Lotion delivers exceptional results. After hours of playing in the sun—whether swimming, hiking, or lounging on the beach—my skin often feels dry, tight, or slightly irritated. This lotion instantly soothes and cools, providing immediate relief. The lightweight, non-greasy formula absorbs quickly, leaving no sticky residue, which is a huge plus compared to some heavier after-sun products I’ve tried. My skin drinks it up, feeling soft, hydrated, and revitalized after each use. The inclusion of aloe vera helps calm any redness or mild sunburn, while coconut oil and vitamin E lock in moisture, preventing peeling and keeping my skin smooth. I’ve noticed it helps maintain my summer glow without the flakiness that can come from sun exposure. Texture and Application The texture of this lotion is a perfect balance—not too thick like a heavy cream, but not runny like some gels. It has a smooth, serum-like consistency that glides onto the skin effortlessly and absorbs in seconds. I appreciate how a little goes a long way, making the 8-ounce bottle last through many applications. For an extra cooling effect, I sometimes store it in the fridge, which feels incredibly refreshing on warm, sun-kissed skin. The lotion applies evenly, and I’ve used it on both my body and face without any issues, even on my sensitive skin. Durability and Practicality I’ve been using this lotion consistently throughout the summer, and it’s held up beautifully as part of my daily post-sun routine. The bottle is sturdy and travel-friendly, fitting easily into my beach bag or backpack. While Sun Bum notes that shipping to certain areas like Hawaii or Alaska may be restricted due to alcohol content, I’ve had no issues purchasing it locally or online for mainland use. The formula remains effective even after multiple uses in a single day, and I’ve never experienced any separation or change in texture, which speaks to its quality. Comparison to Other After-Sun Products Compared to other after-sun lotions I’ve tried, Sun Bum’s Cool Down stands out for its lightweight feel and natural ingredients. Many gels can feel tacky or sticky, and some creams are too heavy for summer use, but this lotion strikes the perfect balance. Its Yuka-approved clean formula also sets it apart from competitors that may contain questionable chemicals. While some after-sun products focus solely on cooling, Sun Bum’s inclusion of nourishing ingredients like vitamin E and coconut oil makes it a more comprehensive solution for skin recovery. Pros Clean Ingredients: High Yuka rating for all-natural, non-toxic formula with aloe vera, vitamin E, and coconut oil. Fantastic Scent: Tropical, coconut-like fragrance that smells like summer without being overpowering. Lightweight and Non-Greasy: Absorbs quickly, leaving skin soft and hydrated without stickiness. Soothing and Hydrating: Calms redness, prevents peeling, and restores moisture after sun exposure. Versatile: Suitable for face and body, great for sensitive skin, and effective for mild sunburns. Travel-Friendly: Sturdy bottle perfect for beach bags or travel. Cons Price Point: Slightly more expensive than drugstore alternatives, but worth it for the quality and clean ingredients. Conclusion Sun Bum Cool Down After Sun Lotion is a must-have for anyone who loves spending time in the sun. Its clean, natural ingredients, delightful tropical scent, and lightweight, hydrating formula make it a standout in post-sun care. My skin absolutely loves it, and the high Yuka rating gives me confidence that I’m using a product that’s good for me and the environment. Whether you’re recovering from a beach day or just need to soothe sun-exposed skin, this lotion delivers on every front. It’s become an essential part of my summer routine, and I highly recommend it to anyone looking for a reliable, skin-loving after-sun product.
