Im thinking of changing my ecu with an aftermarket unit that is apparantly tuned for more power and the rev limiter is raised 1000 rpms. Has anybody done this to thir RZRs? Is this a good thing, the last thing I want to do is wreck my motor.
One company that I found that offers this is called "Procom". (Ebay)Im not familliar with them and what little research Ive done has shown some negative feedback on other ATVs, but no input on the rzr.
I would like to see 65mph. i put in a Dragonfire EFI controller that seems to have freed up some power and Ive installed a heel clicker clutch kit that works amazing from idle to redline, (I think its probably the best upgrade for the RZR). It has my 08 running about 58 on the speedo before the rev limiter kicks in, and just about pulls the front tires on pavement from a standstill!
Also, not to awaken the air filter issue again but Im running a K&N which Ive always thought was a great filter, but after reading some posts Im not sure. Is this a mistake? After a weekend of deep mud riding, my throttle body and intake had a scary amount of dirt inside. The airbox had about 2" of mud sloshing inside, so Im guessing some of it got pulled right through. Whats interesting is that although the throttle body had a significant amount of dirt inside, the boot that connects it to the engine had no sign.. I dont get it. Anyway after cleaning everything up the machine seems to run perfect.
One more thing, I have been running with the spark arrestor removed, I took it out to inspect it, and after seeing how much it restricted the size of the exhaust tip I couldnt bring myself to put it back in. I doubt it makes a difference but it does close the tip down about 1/4" or more. I'll likely be putting a Gibson system on next spring anyways.
As always ant input is appreciated
Cheers to Polaris, the RZR Rocks!!
