In an ongoing effort to beef up and improve performance and reliability in the Polaris RZR and RZR S, we’ve spent sleepless nights contemplating what effect an increased rpm would have on the RZR’s factory crank.
As a result, we’ve decided to release a pre-programmed race map ignition in conjunction with some other quality products for the Polaris. Our new Performance ECU (engine control unit) is being presented at the same time as our 800cc billet stroker crank and high-performance piston and cam.
By releasing these products in tandem, you can have all the electronic fuel injection (EFI) you’ll ever need. With the security of a new controller, you can modify your stock RZR for more speed. The Polaris RZR, RZR S Performance ECU also allows you to map your own fuel map, timing maps, throttle positioning sensor maps and install any size cc motor (including a full 800cc race motor) on your RZR.
As we trust you can see, the team here at DragonFire Racing went to great lengths to create an ECU that works best with its own products. The box increases or decreases your rev limiter to 2500 rpm and increases the fuel up to 80 percent. It can advance the timing up to 32 degrees and the unit is a direct plug-in replacement.
Finally, we utilized the latest technology on the market to create this box, which was tested by the top racers in the field. As a result, the Performance ECU is able to handle any advanced installations you might throw at it.
