This is VR Tuned ECU Flash Tune Polaris RZR XP Turbo | Turbo S Dynamix Big Injectors. Manufactured by VR Tuned.

 

The VR Tuned Big Injector ECU Tune for the Polaris RZR xP Turbo and Turbo S with Dynamix will take your RZR even further with horsepower!  Upgrading to the larger Siemens 80lb Injectors allows us to get more aggressive with the mapping to achieve almost 8 rear wheel horsepower more than our standard tune.  The injectors are very easy to install on the xP Turbo (see link below).  With this new tune, you will need to max out your stock wastegate adjustment by turning the wastegate rod almost all the way in.  With our big injector tune, we are seeing a gain of nearly 25 rear wheel horsepower on just 91 octane (Note: dyno sheet attached shows Big Injector Tune vs Standard VR Tuned File).

Horsepower Gains (dependent on fuel and modifications)

  • 147 rear wheel horsepower on a Mustang Dyno
  • 28 crank horsepower gain using 91 octane with stock exhaust
  • 30+ crank horsepower 100+ octane with exhaust and recommended parts

What does the ECU Flash do?

  • Speed Limiter Raised
  • Rev Limiter Raised Raised
  • Improved Throttle Response - Enhanced E-Throttle
  • Torque Limiters Adjusted
  • Cooling fan temp lowered to 185F
  • Performance Fuel Curve
  • Performance Ignition Timing
  • Left Foot Braking Enabled
  • Boost Correction for High and Low Elevations
  • Much improved driving experience!
  • Read More About Our Testing Here
  • Note: To get the maximum performance out of this ECU flash, please tighten your wastegate rod down to limit the travel. The factory wastegate is very soft and weakens over time. The ECU calls for more boost pressure but the wastegate will not allow for this without adjustment.
What are the benefits of VR Tuned?
  • #1 priority is our customer service to you!
  • Our tuning is used worldwide. 
  • Basic bolt-on performance parts will not require a retune of your ECU. Other efficiency parts such as colder spark plugs, boost tubes, or diverter valves are not required but can help performance.  The ECU will adapt to these changes.
  • We can tune cars worldwide including JDM, EU, Australian, and USA cars for different types of octane or environments.
  • We do not lock, "pot", or keep control of your ECU.  If you decide to take it to another tuner for an upgrade, all flashing ability is retained.
How to Flash Your ECU?
  • We can bench flash your ECU. To bench flash the ECU, you must remove it from your vehicle and send it to us (See Instructions Here).  You can also send us a new ECU to be flashed. Once we receive the ECU, we will prepare the tune file and then ship it back to you for reinstallation. We do not solder or modify the ECU board at all. All ECU tuning is done via bungy probes that have a needle tip to provide an electrical connection.
  • Bring your vehicle or ECU to our facility where we can do the ECU Upgrade here.
  • Order our OBDII Flash cable to be able to flash between a stock and your tuned file.  See Instructions Here
For optimal performance, we recommend:Fitment:
  • 2018 Polaris RZR xP Turbo or Turbo S with Dynamix, 925cc
  • For reference this is a Bosch ME17.9.74 ECU.
