2014-Up Ranger 570 AA Custom Tunes for Power Vision CX, 3 & 4

Aftermarket Assassins custom tunes for the 2014 and newer Polaris Ranger 570, built for the Power Vision CX, 3 or 4 you already own. The factory 45 HP motor is held back by torque limits, a 50 MPH speed limit and a low rev limit, and AA unlocks all three for another 5 to 7 HP.

Why it holds up

• 100% throttle in high and low gear, with throttle by wire limiters disabled on TBW models
• AA timing and fuel curve for 87 or 91 octane, with more mid range fuel
• Fan temps lowered to 195 on and 185 off
• Rev limit raised to 8000 RPM with torque limits removed
• Much quicker throttle response, especially in high gear

Fits

• 2014 and newer Polaris Ranger 570

In the box

• AA custom tune files for your Power Vision, sent by email. No hardware ships with this order.

Good to know

• Factory 50 MPH high and 24 MPH low speed limits removed. Expect around 60 MPH in high gear.
• 2 foot limits disabled, with an optional seatbelt limiter disable.
• Level 1: for the factory exhaust. When properly clutched, 52 to 53 HP or more on 91 octane, or around 50 HP on 87. Peak power is 7500 to 7700 RPM, so clutching is highly recommended.
• Level 2: Level 1 with fueling for an exhaust system. Normally another 3 to 5 HP depending on the exhaust.
• Level 4: Level 2 with fueling and timing for a big bore kit.
• Race fuel tunes are available on request.
• This is a tune file for a Power Vision device you already own.
• After purchase, the store contacts you by email to collect your vehicle and Power Vision device information, then sends the tune files by email.
• Tuning a second vehicle with a PV4 requires an additional vehicle license, purchased through the Power Vision app.
• Tunes are final sale.
