DragonFire Racing has spent the past several years trying to find the perfect balance of performance and reliability for the RZR and RZR S. We have had concerns with increasing the RPM on the RZR with the Factory Crank. So in conjunction with releasing our 800 CC Billet Stroker Crank, Hi Performance Piston and Cam, we are releasing our Pre Programmed Race Map ignition for the Polaris RZR and RZR S.

Now you have all the EFI tuning you need. The new Controller allows you to take modify your Stock RZR looking for more Top Speed, and a better fuel mapp with bolt on performance pipes and intakes. It is also ready for a full 800 CC Race Motor.

• You can map your own fuel maps, timing maps, TPS maps and much more...
• Increases/decreases your REV. Limit up to 2500RPM
• Increase the fuel up to 80%
• Advance the timing up to 32 degree
• This unit is also already pre-mapped, it is a direct plug in replacement
