AA RZR Turbo Launch Control Module

The Aftermarket Assassins Launch Control Module builds boost at the starting line on 2016 to 2021 Polaris RZR XP Turbo and Turbo S models, for drag racing, other racing, or just fun.

Why it holds up

• Developed with DynoJet, with AA wiring, switch, programming, tune and tech support
• Brake boosting alone makes around 7 to 8 PSI in the plenum. With launch control AA sees 14 to 17 PSI, depending on launch RPM, for much faster spool and acceleration.
• On the PV3 gauge, boost goes from negative to positive pressure at the line
• Launch RPM is programmed by AA and can be changed with a Windows computer and DynoJet C3 software

Fits

• 2016 to 2021 Polaris RZR XP Turbo and Turbo S, including CA EVAP and wideband models
• Does not fit RZR Pro XP, Turbo R or Pro S

In the box

• DynoJet launch control module, programmed by AA
• AA wiring harness with launch switch
• USB cable for adjusting launch RPM

Good to know

• AA custom tunes for a PV3 device are required to work with this AA wired and tuned module. Read the full description before ordering.
• AA tunes bought before August 25, 2020 need an update to the latest version, which desensitizes misfire so the machine does not go into limp mode.
• Run this module with an AA clutch kit or any kit with a higher stall than factory. The AA standard kit uses a blue and yellow primary spring with an 1800 to 2000 RPM stall. The AA solid blue high stall spring stalls at 2300 to 2500 RPM and needs 2 more magnets in each AA clutch arm.
• 1800 RPM: Very safe with the AA clutch kit and standard blue and yellow spring, and on 2021 models with the AA kit standard spring.
• 2000 RPM: On the edge with the AA kit and standard blue and yellow spring, and on 2021 models with the AA kit standard spring.
• 2300 RPM: AA kit with the teal primary spring on 2017 to 2020 models, which usually needs 1 more magnet in each arm. On 2021 models, the gray and white spring, though AA does not suggest higher launch RPM on the weaker 2021 clutch.
• 2500 RPM: AA kit with the solid blue primary spring, which usually needs 2 more magnets in each arm or AA 65g heavy weights. Not for 2021 model clutches.
• The 2021 P90X clutch is weaker than the 2016 to 2020 clutch. AA highly suggests the AA primary clutch conversion for launch control on 2021 models.
• Choose the 2 seat or 4 seat version to match your machine.
• For fun riding, set launch at engagement RPM to protect the clutch and belt. For drag racing, AA suggests 200 to 500 RPM above engagement. That takes more brake and builds more boost, and it is harder on the belt and clutches, so use it in moderation.
• Set launch RPM right at clutch engagement. To find engagement, put the machine in high range on flat ground, press the gas slowly and note the RPM where it starts to move. Repeat a few times for a consistent number.
• After install, try launch control without holding the brake. The machine should barely want to move. If it lurches, go to a higher stall spring, a fresh clutch spring, or a lower launch RPM.
• To launch: start the machine and let it idle (the module will not engage above 1500 RPM). Press and hold the launch switch and go full throttle. The machine holds launch RPM. Most riders hold the brake too. Drop the brake and the switch at the same time to go.
• To change launch RPM: install the DynoJet C3 software on a Windows computer, connect the module with the supplied USB cable, open Configure, then Feature Enables and Inputs Selections, then Launch Control. Change the target RPM and click Send.
