AA Custom Tuned Power Vision for 2016-19 RZR ACE 900

The Aftermarket Assassins Custom Tuned Power Vision is a Dynojet Power Vision tuner loaded with AA tunes for the 2016 to 2019 Polaris ACE 900. It breaks the factory throttle limits that keep this motor detuned all the way to redline.

Why it holds up

• Throttle by wire limiters disabled for 100% throttle
• AA timing curve set up for 91 octane with a strong mid range punch and better top end power
• Fuel tables built for this motor to match the timing curve at 100% throttle
• Speed limiter removed in low and high gears. Most riders see 7 to 10 MPH of actual top speed gain.
• Rev limit set at 8800 RPM and fan on/off temps lowered to 190/185 degrees F

Fits

• 2016 to 2019 Polaris ACE 900
• 2017 to 2019 Polaris ACE 900 XC

Good to know

• Level 1: designed for the stock exhaust. A slip on works with it, but Level 2 picks up a little more with a slip on or full exhaust.
• Level 2: same as Level 1 with increased fueling for a slip on or full exhaust system.
• Kid/Valet mode: a limited tune set at 35 MPH and roughly 35% power.
• Custom race fuel tunes are available on request.
• Horsepower gains on this motor vary with temperature and altitude. Average gains for low altitude riding in 50 to 70 degree weather are around 15 HP.
• Seatbelt limiter disabled and 2 foot limiters disabled (gas and brake at the same time).
• Reads and erases most trouble codes and data logs 25 parameters with one push of a button for review on a Windows computer.
• AA recommends its Recoil clutch kits to put the added power to the ground and reach proper peak RPM.
• Ships in 24 to 48 hours, since each tuner is custom programmed.
