2022 Pro R 4 Cylinder Stage 1 Lock & Load Kit
Lock and load your Polaris Pro R 4 cylinder and get ready for some serious kick! The Pro R is an awesome machine, but Polaris left a ton of room for improvement on the table. This simple kit is the best way to wake up your Pro R 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 2 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.
- Kit includes AA ECU flash for 2022 RZR Pro R 4 Cylinder Models **Requires ECU to be sent in for programming** and AA Stage 2 Clutch Kit with primary clutch limiter.
- Works with all models including ones with Dynamix and/or Evap models.
- Looking for the best/most badass ECU tuning available for your RZR Pro R? 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 RZRs and this will show.
- The Pro R 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 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 degrees Fahrenheit (Stock is 190) which is just above the thermostat opening temp. The progressive fan also ramps up quicker to keep you running cooler than OEM.
- Speed limiter removed in low and high gears (Most will be able to run over 100 MPH!)
- More throttle % in low gear and reverse
- Rev limit at a safe 8800 RPM (stock is 8650). Ideal peak RPM is 8200-8500 with the flash, but 8800 is for ramp up overshoot/top speed.
- 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.
- Level 1 Tune: This tune can be run on a bone stock Pro R on 91-93 octane fuel. This tune adds +10-11 RWHP (15-16 crank horsepower) putting you at roughly 240 crank horsepower with just a flash! Our included Stage 2 clutch kit helps belt grip and gain additional low to mid-range power. This tune can be run with an aftermarket exhaust without any issue, but our Level 2 tune is the best option for aftermarket exhaust as it's slightly richer for more power.
- Level 2 Tune: This tune is developed for a Pro R with aftermarket exhaust on 91-93 octane. It has just a bit more timing and a bit more fuel over our Level 1. This tune adds +16 RWHP peak and a massive +19 RWHP at 38 MPH (This is gaining roughly +25 crank horsepower) putting you at roughly 250 crank horsepower with just a flash and exhaust! Our included Stage 2 clutch kit with this tune really helps the belt to grip and to help drive the extra power to the wheels. Due to how these motors/tuning works, this tune should work with just about any aftermarket exhaust, but was tested and designed with our AA slip-on exhaust (AA header now available!).
- If you're unsure if your Pro-R is an EVAP model or not, check your Emissions Control sticker located on the front driver's side frame rail above the master cylinder. See pictures for location.
- More tunes coming soon!
- *** ECU MUST BE SENT IN FOR PROGRAMMING: Aftermarket Assassins, 2348 75th Ave, Osceola, WI 54020 ***
- The ECU is located behind the passenger (rear passenger if 4 seat) seat. Remove the top panel behind the seats, then remove the fabric panel to expose the ECU. Remove the torx bolts and ECU connector
- Customer is responsible for shipping to AA, a shipping label is not included in the price
- 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 to determine if it's an Evap model or standard, and we'll 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 ECUs. 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.
- If you have any other needs in these tunes, or any concerns; please e-mail!
- Stage 2 Clutch Kit includes: AA Recoil magnetic adjustable clutch weights, setup/installation sheet, primary spring, secondary spring, butter shift washer/shim for increased spring preload and less spring harmonics
- Optional AA custom helix to upgrade your S2 clutch kit to a S3 clutch kit. This is highly suggested as it adds even more acceleration and helps transfer the power to the rear tires. The helix also cuts down on secondary slop/clanking.
- We highly suggest our Revolver Billet Clutch Cover with Tower Lock to strengthen the clutch and provide more airflow for even better cooling
- The only special tool needed with our clutch kit is our Compression Tool #1
- For more information on our Stage 2 Clutch Kit please follow this link: RZR Pro R 4 Cylinder S2 Clutch Kit
- Follow this link for instructions on locating/removing ecu
- Oh... and get ready for your Pro R to flat out rip!

Fit Great, Nice Replacement at a Low Price
Color: 12PCS side brushes for Freo X Ultra/Freo Z Ultra/Freo X Plus
Our Narwal robot vacuum needed some replacement side brushes and these seemed to fit the mark. They went on fine and are working great. 6 pairs for under $20 felt like a good price point.

My house has never been so clean!
Size: 05-11S
As a neat freak, this has been one of my favorite purchases recently. Hands down. No doubt. Our house has seriously never felt so clean. With four boys coming and going, plus a cat, plus my wife and I both working out of the same house, this place gets dir-r-r-r-ty! But now, I just set this little baby up and get it goes to town.
Note: the first several times that we used it, the machine's debris holding chamber was LOADED. We ran it until the battery died (and it returned to it's charger automatically), emptied it, and then ran it again as soon as it was fully charged. But each time that it ran, it was completely full! Every single time. None of us can believe how dirty we were living.
Note #2: We now take it upstairs to do a deep cleaning there. We had a little bit of a learning curve to make sure that all of the electric cords and such were off the floor. (They untangle easily, btw, if you forget). My son with the cat had a room that used to smell terrible... it smells almost normal after we ran this several times through there. And the volume of cat hair that this thing picked up is crazy amazing. Hair that we didn't even see. I didn't know cat hair smalled badly, but it must've. Room smells pretty decent now (not perfect - there still is a smally boy living in there)!
Note #3: We keep a pretty clean house. That is what is amazing about this thing. It makes it really clean.
Note #4: After the first several runs, make sure that you clean the roller brush. It will make a difference. The tool that comes with the unit that looks like a comb does a great job. If you get hair or thread or similar wrapped around it, use the handy dandy letter opener-style cutter to easily and safely clean it out. The blue parts on bottom around roller remove easily for deep cleaning. Do it! Easy and worth it for better future results.
Note #5: Does all types of floors really well. We have ceramic, vinyl, short carpet, marble, deep carpet - all on the first floor of our house --- NO PROBLEM for Eufy! It moves with ease between them all.
Note #6: Problem areas? We have a screened in porch that has a door that allows tiny little leaves in under the door. I'll just set the Eufy out there and forget about it. When I see it again, the machine has run out of juice and the floor is perfectly clean. Or my basement office. Set it in there at the end of the day, close the door and forget about it. In the morning, the floors are clean and the machine is sleeping where it ran out of power. I take it back upstairs, empty the cannister, and put it back on the charger.
Last note: It gets in tight spaces. It cleans edges beautifully. It spends more time on a room than we ever would, so I guess that is why it cleans so well. It gets under most of our furniture. Around most of our chairs. And oh - I almost forgot - this vacuum is SO-o-o-o quiet. With our upright, you can't hear yourself think. With this thing, I can be do my work uninterrupted.
Disclaimer - I have wasted a lot of time just watching machine in amazement and awe! Thankfully I can now walk away from it - although the 7 sessions with a therapist to get me to break the habit were a pain. ;)
I highly recommend the machine - if you couldn't already tell! I came back on to Amazon to buy a unit for my in-laws and saw the opportunity to avoid my job for a little bit to write this review! Funny, but I am glad that I did. This little fella is totally worth it. If you are thinking about which brand to buy, you can't go wrong with Eufy.
Kudos to the manufacturer and development team!
Note to manufacturer: Can you please develop a machine to automatically climb and clean stairs (cook, do toilets, do laundry)... ?
People, you are going to love this vacuum!

Great robovac! We named ours “Robby the Robovac.”
Size: 06-15C Max
I hesitated for years to pull the trigger on getting a robot vacuum, and I shouldn’t have. If you are on the fence, get one. This thing has been worth the $250 in the first month, alone. (I compare it to a maid service fee.) It automates the simplest but most essential task of cleaning, because most dust and dirt ends up on the floor. It also forced me to finally tidy up all the wires and miscellaneous junk I had laying around on the floor, and thereby also eliminate areas where dust and dirt would accumulate, both of which were unexpected side benefits. It also frees up time to then wet mop and clean other places more easily, and tacitly helps me WANT to follow through with those final stages of cleaning that are easier because it takes care of the most time-intensive, initial stage of cleaning.
It has been a life changer for us. The first week made the house smell a bit dusty because it kicked up all the latent dust from the corners, under furniture, and in the rugs. But once it got through that stage, the whole house looks and “feels” so much cleaner and smells nicer. Subtle but significant difference.
I live in a one-story bungalow with mostly hardwoood or laminate floors, with a low-nap Berber floor covering in my master bedroom. I have a mid-size wire-hair dog who sheds normally, and it is perfect for picking up dog hair. I also have a nine year old son who adds to the dust and dirt. The suction is great on all of our surfaces. It works better than my stand-up “cyclonic” Hoover. Having three suction settings allows you to adjust the noise level depending on how clean you need the suction to be. The side brushes seem trite but definitely do work to help collect and”funnel” dirt into the collection bin. They also hit under furniture legs and walls edges to help collect the dirt that hides there.
The collection bin does need to be emptied frequently (every few uses, especially when you first use it), but I look at that as letting me know what would have been on my floor if I didn’t have the unit. It is amazing how much it cleans off the floor even after the first wave of cleaning.
The different cleaning modes are also well thought out: edge cleaning, spiral-spot cleaning, and random walk cleaning. I use the edge cleaning mode the most because dust and dirt tend to congregate along the edges.
Three downsides that are probably fixed in higher end models. First, getting the app to work was unnecessarily frustrating and difficult because I forgot my exact WiFi password. The problem is that the interface requires you to go through about a five minute process for each “guess,” which made syncing to the app much more frustrating and unnecessarily slower than it should have been. Then with each failed attempt, I also had to also manually reset the entire unit by pressing the power button for 20 seconds. They should program it to test the password quickly so the entire syncing process does not take five minutes until you find out you typed the password incorrectly. (Especially because WiFi passwords are case-sensitive, so it is easy to mistype it). Once I typed the correct password and synced it, the problem was over, but it was frustrating and time consuming.
Second, controlling the unit manually through the app is difficult because of the lag time in the signal through WiFi. So any time I manually steer the until, I use the remote and not the app. Not a big deal, but something to note.
It is also too loud to schedule vacuuming at night. It woke us up the first three times it ran a scheduled overnight clean, partly because we keep our bedroom doors open at night. We are still on COVID lockdown, so I can’t just schedule it to run during the day while we are at work. So I just run it in the background during the day or when I leave to go to the store or take the dog for a walk.
Nonetheless, none of those are dealbreakers, mostly just minor inconveniences that are acceptable at this price point. It still earns its five star rating for fulfilling its primary purpose and then some.

Life Changing, and Superb Customer Service
Size: 12, Size: 12
Hey folks. I bought this model of Eufy while on sale a little over six months ago, and have used it daily since. Thinking about buying one? Do it. No regrets here, and I wish I had purchased one when I first began thinking about it a year and a half ago.
I live next to the Gulf Coast in Florida, and coastal living = constant sand. Fine, white quartz sand ends up in your home constantly regardless of how many rugs and floor mats you place at entranceways. Our home is completely tiled, and the powdery sand sticks to everything, so it’s a never ending battle keeping the floors clean. We used to sweep pretty much daily in the morning, and then use a hand vac around corners in the evening just to keep up with it. We also have one cat, a Great Pyrenees, and an English shepherd, so sweeping daily was necessary to keep fur from drifting into giant globs in corners and under furniture.
After purchasing the Eufy, and charging it up, we no longer have to sweep every day. The eufy is simply fantastic at getting up all the pet fur and sand. Instead of sweeping every morning, I now stare off vacantly out the window while drinking my coffee, and the eufy sweeps for me.
My five year old named our Eufy “Mumford” and we created a face cut out from a roll of white window cling vinyl (purchased the white vinyl window cling on amazon too- it’s meant for those Cricut machines) for the little guy. Mumford is now a treasured family member.
For reference, my house is all tile and is about 1500 square feet. The eufy can clean our dining room, living room, kitchen, bathroom, and playroom on a single charge, but since it doesn’t map out the rooms, I do place it in one room at a time, and block it off or shut the door. It does fine if I don’t block it off, but takes longer to get the job done. Since I keep the common areas clutter free, it is no trouble running the eufy every morning. I have my kiddos pick up anything on the floor, and then we hit the button and go about getting breakfast ready. If you are messier, or have a lot of clutter in your home- a Eufy probably isn’t the answer. It can’t do a good job if it isn’t able to roam around freely to vacuum.
It fits under all of our furniture, and maneuvers well around my oak dining tables and chairs.
If your home is very large and multi level, and you don’t want to pay attention - you may want something that maps your home. Eufy bumps around haphazardly, and when you leave it on long enough and run it consistently, it does a great job. I do not run it when we aren’t home, and I do not run it at night when we are sleeping. The last thing I want is for one of the dogs or the cat to get sick, and then have eufy run over the mess. Eeew. If you have pets, don’t make that mistake.
If your home is larger than 1500 square feet, you’ll likely have to clean different sections at a time maybe on different days or nights of the week.
Customer service is fantastic. After six months of daily use, our unit had a malfunction. The bumper on the right side would stick, and our unit would spin constantly clockwise. I contacted Eufy, and they did some troubleshooting with me, and when that didn’t fix the problem, I was sent a brand new unit. They emailed me a free return label to ship my old one back to them at no charge.
All in all this is an excellent and helpful product, and the company that makes it is reliable and true to the warranty. I know several people that own one and love it, and have recommended it to friends and family members.
Buy one!!!!!!
