- AA ECU flash for 2022-Up RZR Pro-R 4 Cylinder Models **Requires ECU to be sent in for programming**
- 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 RZR's 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 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 degrees Fahrenheit (Stock is 190) which is just above the thermostat opening temp. The progressive fan also ramps up in quicker to keep you running cooler than OEM.
- Speed limiter removed in low and high gears (Most will be able to run over 100mph!)
- 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 +10-11rwhp (15-16 crank horsepower) putting you at roughly 240 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 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 level 1. This tune adds +16rwhp peak and a massive +19rwhp at 38mph (This is gaining roughly +25 crank horsepower) putting you at roughly 250 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 (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!
- 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 connectors.
- *** 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
- 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 a 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 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 Pro R 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!

This was a Good gift for the right person
Format: Paperback
My nephew wanted a similar book- this had better reviews and I heard about lots of things that he’d done with this book. Glad I got it

From the creator of the Godot Recipes site!
Format: Paperback
Absolutely loved this, takes you through building 5 different games from start to finish, and explains not only how to do things, but it also explains the why! Throughout the course of making these 5 games, you also get introduced to many of the Nodes within Godot, explanations on how they are used, and gives you some experience using them! Feels good to add more tools into your toolkit as you become more familiar and comfortable using more Nodes.
Even though this book is not intended for beginners, I would still recommend this book. It comes with a link where you can download example files and get going with minimal effort, however to get the most out of the book I would try to recreate stuff yourself.
I found it very useful for easing myself into trying out 3D development. I've been doing 2D for years, and am currently developing a 2D game in Godot, once I complete that I'll be diving headfirst into 3D and this book gave me a lot of insight, and I feel much better about the whole process.

would have been better as a blog
Format: Paperback
First off, I have read over half of this book, but ultimately decided to put it down because it had a low signal-to-noise ratio. If the second half is filled with magic, I apologize in advance.
What I liked:
* The author is very honest. He does not shy away from discussing his failures (and successes).
* The postmortem on the game "Life of Pixel" was especially good.
* Interviews from various indie studios are sprinkled throughout.
What I did not like:
* A number of pieces of information were already out-of-date. This makes me think that the concepts should have been discussed at a higher level. For example, specifics about game engine costs are discussed. These numbers have changed since E3 of this year. Definitely recheck any information before formulating a plan based on the book's recommendations.
* The indie studio interviews are a wasted opportunity in that they each interview has the same set of questions. It's like a questionnaire was sent out via email and the responses were pasted into the book.
* When discussing commercial options, such as engines or other software packages, blurbs once again appear to be cut-and-pasted (this time verbatim from the package's web site).
* Some of the advice is too broad and too light. For example, when writing about how to create a press release, the author discuss how to write in the active voice. I'm frankly not looking for writing tips in my Indie Game Developer Handbook.
* The book is filled with tons of web links. My paperback copy was not so useful here.
I ultimately left the book with the impression that the information would have been much better in the form of a blog. The author could have really gone in depth with the parts of the book that shined while keeping the surveys of topics in a form that serves them better (i.e. web links on the web).

Helpful information and Questions to consider
Format: Paperback
As a writer of science fiction and fantasy I had already looked into the physical aspects of the worlds I was creating, but I quickly realized I needed to include society and culture in the worldbuilding. I started a search for information, questionairres, or guidelines to use and found very little that would be helpful to me as a writer. Until I came across this book. It's exactly what I needed. It touches on multiple aspects of beliefs and practices and asks questions to help you think through what you want for your worlds, even if it's mostly backgroud. A very useful tool.
