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

- Oh... and get ready for your Pro R to flat out rip!

WOW! This printer has been VERY impressive thus far *UPDATE*
Color: Black, Style: ET-2800-B, Pattern Name: Printer
My old printer broke (sooner than I would have liked) so I did A LOT of research before deciding to buy this Epson EcoTank printer for home office use. This is my honest review of it this far and I will definitely update my review if I run into any issues.
So far, this printer has been pretty impressive (I've been using it for about a month). The price was pretty average for a printer... but I personally think all printers are overpriced so it was a bit more than I would have liked to spend. It is smaller and more lightweight than I was expecting which is a plus because it takes up less desk space than my previous HP printer.
It is very easy to set up, comes with step-by-step easy instructions and guided instructions through the app. It only took me about 10 minutes (Mostly just waiting for the printer to initialize on its own). It is very easy and surprisingly satisfying to fill the ink tank. I like the idea that this ink might last longer than traditional cartridges and won't have as much plastic waste that went along with my old HP Inkjet.
I have printed plain black and white documents as well as photos. I print all my photos at home, which is most of the printing that I do, so quality was important to me. The photos came out with pretty good quality! No ink smudges or off colors, colors are bright/vivid, and it is easy to modify what paper you're using with automatic prompts on the printer.
Now for the negatives and the reason I'm giving this 4 stars... app to printer connection issues. This was a big issue with my old printer as well. I'm pretty tech savvy and I just have no idea why this is still always an issue for me. There is an extra Epson app that you are supposed to download for printing. Sometimes it can find my printer, sometimes it can't. Sometimes it gives me printer errors or won't let me print documents. And now every time I go to print something it says the paper being used doesn't match the paper settings so I have to bypass that error message (even though it does match in settings and the app, and this happens for both regular paper and photo paper). I've turned everything off and back on again, but the issues with consistent connection and error messages are still an issue.
Usually with some fiddling around, I can get the documents/pictures to print but sometimes it feels like I'm jumping through unnecessary hoops. I'm still working out the kinks so if I find some magic solution I'll update my review. Considering this is an issue with most home printers I've used, it's not a deal breaker.
All in all, if you are looking for a new home printer, I would definitely recommend this one. The quality has been great for me and I am pleased with my purchase (so far).
Hope this helps!
*UPDATE*: I have now printed HUNDREDS of photos, they are all excellent quality, and my ink tanks are still mostly full. This is WAY better than my HP printer as far as ink longevity. Changing my review to 5 stars just based on how long this ink lasts. User interface is still a tad annoying but so worth it regardless.

Almost a year after purchase and this printer has not let me down!
Color: Black, Style: ET-2800-B, Pattern Name: Printer
I wanted to wait to write a review on this printer to see how it held up over time. Happy to report, after almost a year, it is still working perfectly! I was very nervous about purchasing a printer since it was my first time having to shop for one and almost every printer I looked at had something negative to say about the product. After extensive research, I decided to take a leap with the Epson EcoTank 2800.
I was looking for a printer to use for recreational use. Something with decent print quality and longevity as well as something on a reasonable budget. I normally print full pages of color and have been using it regularly for around a year and I have about half of the ink that came with the printer left. Safe to say, the ink lasts a while. The quality may not be the top of the line quality you can get with a more expensive printer, but for the price and just everyday use, the quality is satisfactory. It was easy to set up and walked you through the instructions to connect to devices and configure it. The screen is a little small but if you can overlook that, it really is a nice printer. I have used regular printer paper, card stock, and sticker paper with this printer and I try to load only a few sheets at a time to avoid a jam but I haven't had any issues with it so far.
Overall, I am extremely happy with my purchase. It can be extremely difficult to find a decent printer and some reviews can be misleading or leave you with questions on if the product is for you. If you are looking for something for printing everyday with decent quality and ink consumption that won't cost you a fortune, this printer is definitely worth taking a chance on!

My Epson printer is total junk!
Color: White, Style: ET-2800-W, Pattern Name: Printer
I have had many printers over the years. I started with Canon dot matrix printers, and then ink jet printers. In the old days, and ink cartridge contained all the colors, so if red was out, you tossed away the rest of yellow and blue too. They were pricey and wasting ink wasn't something I was OK with. I would pull ink cartridges from dumpsters outside office supplies stores, take them home and draw the ink from them to fill my cartridges with. Then Epson came up with a cartridge for each color and black . That's when I switched to Epson and have used them ever since. I did have an HP in there when I got such a deal I couldn't pass it by, but after several years it died and I switched to Artisan printers. I still have an old 810 that is finicky and I don't want to have to coax it just to print a few pages. I got a WorkForce printer ,used it several times after I got it, and then it sat idle for 5 years or so. I moved recently and decided to set up the WorkForce printer. The new ink cartridges were practically new, but sat for 5 years maybe, so the nozzles and print head needed cleaning, I expected this. It uses mass amounts of ink to do this so then I was out of ink. I ordered new cartridges, and back to cleaning when they were inside. I never got anything to print, plus, the new paper I ordered was as glossy and slippery as photo paper, and the rollers couldn't grip it.
I gave up and ordered this printer as a replacement.
Setup went OK until I put paper in, then the rollers were slipping and I got jam messages, even though nothing was inside. I pulled the paper and let it finish the initial process. Then I put paper in when it wanted to align the print head. It fed paper OK for now, so I guess maybe I didn't get hosed on this Epson as I did buying the WorkForce Epson.

This is a frustrating printer!!!!
I'm using WIFI network to connect the printer to my laptop computer. I like to be able to print or scan from anywhere in the house. If you purchase this frustrating Epson printer, you now have a ball and chain around your leg. You can't print a simple document without some kind of error code popping up and requiring that go look at the minuscule little screen and try to figure out what button you must press to get the document printed. If I have to be right next to the printer, I might as well use a wired connection. I am disabled and it's a real inconvenience for me to have to go to the printer and squint at the tiny screen to try to figure out why it's been ten minutes of my time and I still haven't gotten my 1 page document in my hand. High speed printing is not high speed when you can't get a printed page without having to make several trips back and forth to the printer. I set the default paper to the standard plain white letter paper, only to find it wants to scan to photo paper, so it just sits there like a block of cement and nothing gets done. I had an Epson Artisan 810 that I really liked, except for the automatic feeder quit working so you had to stand there and feed each sheet to be scanned by hand. I didn't want a sheet feeder on the printer because they break down and the you're feeding by hand anyway. I just hate printing anything at all now because of this printer. I wasted several hours one day trying to print documents that I downloaded and needed a physical copy to present in person for a project I'm doing. Normally I would send a PDF file, and let someone else bother printing if that was necessary. After years of purchasing Epson printers, this is absolutely the last Epson I have spent my money on. Never ever again. The first clue should have been when the quick start guide suggested using a smart phone to set up the printer. I'm not going to work from my 5 x 7 phone screen when I can instead use a 15 inch laptop screen, and keyboard. It's simply a stupid idea. Sorry, but no more Epson for me ever!!!!
Update:
4/10/26
This is absolutely the most useless and frustrating Epson printer that I have ever ever owned. I cannot see good close up I need reading glasses to read. The digital screen on this printer is minuscule it's like a postage stamp size absolutely worthless. I have to carry a magnifying glass over to the f****** printer so that I can see what that little miniscule screen has to say on it. The most frustrating thing is every time I want to print something which is rare I don't print things every day the printer is not available is the message I always get I go over there by the printer I turn it off I turn it back on, that should clear out any crap that's on it so it's ready to print right? No you would be dead wrong! Instead you get a stupid little mini School screen and wants to be set on copy mode. I don't want to copy anything I don't want to scan anything I just want the damn thing ready to print. Anyway you come back to your your phone and you want to print and a printer still not available. I literally destroyed my phone I was that pissed off. I'm too old to be frustrated like that all the time. At 75 years of age I have had my share of printers over the years starting with the original dot matrix ones. Absolutely none of them were as difficult to use as this stupid printer I got now from Epson. When you want to print something you should be able to send it to the printer and it should print. You should not require a phone app to set the damn thing up! One thing I'll say, it's pretty good on ink because you can't make the damn thing print when you want it to !!!!!!!

Quality Printer
Color: Black, Style: ET-2800-B, Pattern Name: Printer
Wonderful multi purpose printer. I bought this months ago and finally got it set up. Set up was easy. Love that the printer is so light weight and fairly compact that I can move it wherever if needed. The supply of ink that came with it was awesome. The ink goes a long way. I have printed out a lot of photos on this printer and the quality has been very good. I have not encountered any paper jams. The photo printing has not been smudged nor has the color been uneven. From documents to photos this little printer does it all and does it very well. When my work printer dies I will be replacing it w another Epson Eco Tank for sure.

Printing is great, wifi is a problem (I figured out how to make it work!)
Color: White, Style: ET-2800-W, Pattern Name: Printer
I was on the fence about buying this printer because most of the 1 star reviews all said the same thing... "The Wifi would not work"
So I followed the instructions, Turned on the print, downloaded the IOS app, connected to the printer via Bluetooth, installed the ink, initialized the printheads. While that was going on, the app asked me to setup the wifi. a List of SSID's came up and I selected the one I wanted. I put in the password and it connected and the icon on the printer turned blue. I have a Unifi setup and I could see that the printer connected to access point #3 @ 2.4ghz and got an ip address. I locked the IP address to the printer.
(For my instructions to work for you, you need to make a reservation or lock the ipaddress that your DHCP server provided to the printer. ) If you don't do this, you will get a different address every time you turn the printer on and the computer and app will not be able to find the printer.
When the initialization was complete, the app on my phone said it could not connect to the printer. I decided to try to connect to a computer and come back to the phone app. I downloaded the software package from Epson and ran it. When it went to connect to the printer it could not find it and brings up a list of troubleshooting steps that are not likely to do anything.
There are videos about this problem and they are all useless. I am an IT professional with 26 years of experience. I am not going to unplug the printer and wait five minutes, I am not going to re-boot my router, I have a Unifi network environment with over 150 devices connected... (I have great wifi coverage, I am not moving my printer anywhere) My network works just fine, this printer is the issue!
So at this point, I know that the printer IS connected to my wifi and it got an IP address. This is not a wifi problem as everyone seems to think it is. It is an issue with the Epson software.
I decided to try to install it via the windows printer installer. I selected install via TCP/IP and put the ipaddress that my Unifi system provided to the printer. Windows found the printer and since the Epson app had already installed the drivers... just asked me what drivers I wanted to use. The ET-2800 showed up on the right hand side of the screen. I selected it, it installed and I was able to try a test print. It worked fine. I can print from my computer to the printer via the network.
Next was the phone app. The phone app has the option to find the printer via the IP address. I put the IP address in and it found the printer. The phone app works now too.
So, It took me some time to get this working, it should not have taken any time at all if the software worked correctly. The printer is really nice, it is a shame that the software is so bad when it comes to connecting to the printer.
So if you decide to buy one of these printers, save yourself the headache and just install using the ip address, it is quick and easy that way and it just works. I would have just purchased an HP printer, but I did not want to deal with all the issues of their subscription ink service. I feel like the cost of ink makes this printer worth the hassle of getting it to work.
