AA Custom Tuned RTD w/ECU Unlock for 2022+ RZR Pro R 4 Cylinder

The AA custom tuned HP Tuners Remote Tuning Device with ECU unlock lets you flash the Bosch MG1 ECU on the Polaris RZR Pro R 4 cylinder from your smartphone. No programmer can flash this ECU until it is unlocked, and AA handles the unlock.

Why it holds up

• Level 1 adds +10 to 11 RWHP on a stock Pro R, roughly 240 crank HP
• Throttle by wire and 2 foot limiters disabled, speed limiter removed in low and high gear
• Fan on/off at 180 F (stock is 191), with a progressive fan that ramps up quicker
• Rev limit at 9200 RPM (stock is 8650), with ideal peak RPM of 8200 to 8500
• Start in any gear with the brake, and more throttle in low and reverse

Fits

• 2022 and newer Polaris RZR Pro R 4 cylinder
• Works with Dynamix and EVAP models

In the box

• HP Tuners RTD
• OBDII to Polaris diagnostic port cable
• Credits needed to flash the ECU
• One AA custom tune (more tunes optional)
• ECU unlock performed at the AA facility

Good to know

• Level 1: bone stock Pro R on 91 to 93 octane
• Level 2: aftermarket exhaust on 91 to 93 octane. Adds +16 RWHP peak and +19 RWHP at 38 MPH, roughly 250 crank HP
• Level 3: for BC drop in camshafts, with revised fueling to fix hot starts
• Clutching is highly suggested to help belt grip and put the power down
• The RTD also logs engine data and reads and clears trouble codes from your phone
• To check for an EVAP model, see the Emissions Control sticker on the front driver side frame rail above the master cylinder
• The ECU must be sent to AA for the unlock unless you buy a new ECU outright. After the unlock, the ECU can be flashed any time with the device
• Instructions for sending in the ECU are sent within 1 business day after purchase. You cover shipping the ECU to AA
• Standard unlock averages 4 to 10 business days. AA completes the work in 1 to 2 business days once the ECU arrives, and the rest depends on shipping time to and from AA
