2019 RZR XP Turbo & Turbo S California EVAP Model Maptuner X

Apr 19 2019


Evolution Powersports is on the bleeding edge once again with our 2019 XP Turbo EVAP California model ECU programming. These tunes will transform your already fast Turbo into an absolute animal! With our Maptuner X Programmer package, there is no need to send in your ECU – Maptuner X allows you to flash your ECU through the vehicles diagnostic port. A large color, app driven, touchscreen makes tuning a snap. Also with datalogging, monitoring, code read/reset function, allows you to accurately see what is going on in your vehicles engine. With a Plug n Play AFR module, you can monitor and log air fuel ratios in real time!

NOTE: Maptuner X programmer gives customers access to tune Stages 1,2 & 3 included in the price.  Other programming options are available in the “add ons” section of this page.

How to identify if you have an EVAP model: California vehicles have an extra control module on the floor below where the ecu is mounted.  (see picture below)

2019 RZR XP Turbo & Turbo S CALIFORNIA EVAP Model Maptuner X

Maptuner X for the Polaris RZR XP Turbo is what many customers have been waiting for!   Maptuner X is a consumer hand held ECU flashing device similar to many diesel programmers on the market except with more capability.  With it, you can flash your own ECU via the touch screen interface and included cabling.  The cable plugs into the OEM diagnostic port.   With Maptuner X, you can install the same proven EVP programs.  Not only that, Maptuner X has live datalogging capability, DTC Reading/Reset and many other features.  It is also compatible with most Polaris, BRP and Yamaha vehicles meaning you only need one device to tune many vehicles! (additional vehicle tunes must be purchased).  You can return your vehicle back to stock at any time! 

Evolution Powersports has completed dyno  and field testing of the 2019 XP Turbo EVAP California models.  Polaris made many changes to both the fuel system and tuning of the Bosch ME17 ECU. The biggest change is the fuel system was changed from a return style, rising rate setup to an automotive type return less configuration.  The new hardware includes a separate fuel pump controller which varies the pressure to the fuel rail based upon input from an inline fuel pressure sensor and programming.  The controller accomplishes this by raising and lowering the voltage to the pump.  When the vehicle is keyed on, the fuel pressure initially rises to approximately 70psi.  Once the engine is started, the fuel pressure drops to 40 psi and stays there until the engine sees boost pressure.  In boost, the controller raises the fuel pressure back to 70 psi.

The system makes for a much better running and safer setup as compared with earlier models.  EVP has made more power with our tuning on this new model than any previous generation, stock turbo, stock injector vehicle.  Stages 1-5R are done using the stock injectors and stock fuel pump!  Not only that, our tunes for this vehicle are the most refined we have done for this family of vehicles.  The EVAP model is also safer because the return fuel line has been eliminated and in general, the fuel pressure is lower than the previous rising rate setup.

All programs have the following features:

  • Massive wheel horsepower gains
  • Rev limiters raised by 500 RPMS both high and low gears – custom rev limits upon request
  • Speed limiters raised: High gear-120 MPH, low gear raised by 10 MPH, reverse raised by 9 MPH
  • No piggyback fuel controllers to mess with
  • Torque limits raised (makes vehicle more responsive)
  • 2 foot braking enabled
  • Dramatically lowered coolant temperatures by manipulating the fan on/off temperatures (EVP was the first company to do this)
