Aftermarket Assassins '16-'19 Polaris RZR ACE 900 Custom Tuned Power Vision

Aftermarket Assassins '16-'19 Polaris RZR ACE 900 Custom Tuned Power Vision

If you are looking for an easy to use ECU tuner loaded with the most badass custom tunes on the market, you've found it! This Dynojet Power vision is a very simple, yet effective device that programs your ECU in a few minutes, and easily allows you to switch between tunes, or return to the factory tune. The PV has the advantage over other ECU tuners as it actually reads what's inside your ECU before tuning. This ensures the correct tune is being loaded, making it a very safe device. The AA custom tunes deliver the most possible power gains. With our expert knowledge of Bosch throttle by wire ECU tuning, we are able to get around factory limiters, make a more responsive machine, and of course create more horsepower and torque. Our tunes are loaded on the Power vision just for your machine, so all you do is open the box and download them into your ECU. We recommend clutching with a tune to get the most out of your vehicle. See below for even more features of our custom tunes.

Big horsepower gains! As you probably know, the ACE 900 motor for 2016-19 is very de-tuned from the factory (Just like the 15-Up RZR 900). The throttle is limited by only allowing so much air to enter the motor before it closes throttle to see the acceptable amount. These limits are hard to break, especially all the way to redline. Many other tunes will open the throttle a little more at first, but then still close when you get over 8000 RPM. This is why it's important to see a dyno sheet or data log run up to top speed where it will eventually hit the rev limit. If power or throttle tapers off, you know the tune is not as good as ours. That being said, horsepower gains depend on air conditions such as temperature and altitude. If you have less air to start with such as in very hot temps, or at higher altitudes, your throttle will open more(with the stock tune) than those in low altitude or colder temps. Basically, no matter where or what temperature you ride in the stock machine will make the claimed 75hp to the crank. Now lets say we are dynoing at low altitude on a cold Minnesota day of 10 degrees. We load this tune in for 100% throttle no matter what, now we can make huge horsepower... let's say 95 crank hp. Lets take that same machine and go to Florida with some nice hot sticky weather in the summer. We might only make 85 crank horsepower. Moral of the story is that on this particular model, your horsepower gains vary depending on temp and altitude. No matter what we promise you will notice a huge gain, and not even be close to a stock 900. Average gains for your low altitude riding in 50-70 degree weather will be around 15hp. We guarantee no one else is making any more power than our tune, despite claims of higher horsepower which were made in colder temps.

Wondering why go with our tune(s) over the dynojet tunes? We go the extra mile to make sure everything is gained, and have a few extra tricks up our sleeve because we test in the real world. Other maps take their time to hit peak timing numbers which really hurts performance. Our map gets you into peak timing quicker, so max power seems more instant. We also have a great fuel curve that is designed to go with our timing curve, and offers better fueling for more power at WOT. We also do some work with torque limiters as in the dirt we saw throttle closures when spinning the tires. Our map fixes that issue giving you 100% locked power delivery. We also do the easy things like up the speed limiter to where you will never hit, disable 2 foot limiters, disable seatbelt limiters & more. Basically, this is the all out tune that has all the features you want built right into it.

Features:

• Much quicker throttle response and power delivery
• Throttle by wire limiters disabled - 100% throttle!
• AA's wicked timing curve is setup for 91 octane and delivers a huge punch in the mid range and much better top end power
• Fuel tables optimized for this motor and to go with our timing curve with 100% throttle
• Fan on/off temp lowered to 190/185 degrees Fahrenheit
• Seatbelt limiter disabled
• 2 Foot Limiters Disabled (gas/brake at the same time)
• Speed limiter removed in low and high gears - Most will see 7-10 MPH actual top speed gains! 
• Rev limit at a safe 8800 RPM
• Very easy to use tuner that can also check and erase most trouble codes
• Easily data log 25 parameters with 1 push of a button and review on your windows computer later
• The Level 1 tune is a huge increase and is designed to work with the stock exhaust. A slip-on will work with this tune, but you can pick up a little more by going to our level 2 tune if you have a slip-on or full exhaust. 
• The level 2 tune is the same as level 1, just with increased fueling for a slip-on or full exhaust system.
• Kid/Valet Mode: this is a limited tune set at 35mph and roughly 35% power. Great for kids who don't need all the power, yet!

Fitment:

• Tuner is loaded with tunes for the 2016-19 ACE 900
• 2017-19 ACE 900 XC version
