fuel ignition control

I want to upgrade my ignition / fuel controller. I want to remove the speed limit as raise rev limiter. Running basic stock RZR it does have RZR S exhaust but other wise engine is stock. Any thoughts or recommendations

Never heard of a speed limiter on a rzr, they do have a rev limiter. You could just get the stock ecm re-flashed with a S program by any dealer, this would raise the rev limit to 6800 i think. Or check with these guys.

Another opition:

S&S will reflash your ECU for whatever setup you plan on using. Exhaust, Intake, Exhaust & Intake, Stock, ect......... $150

Sent mine in and did the 7,000rpm rev limit and for Intake & Exhaust. Runs very well and I did notice a slight power increase.
