For on-the-fly fuel mapping, the removal of factory-imposed speed governors / rev limiters, and a whole lot more, Arctic Cat Wildcat ECU tuners are the way to go! Some riders get their Arctic Cat Wildcat ECU tuning done by removing the module and sending it out for a reflash. But if you want the option to flash / reprogram your own electronic control unit, your best bet is to install an Arctic Cat Wildcat ECU upgrade like the ECU tuners available at Everything Arctic Cat Offroad. Not only are the ECU tuners we sell completely plug-and-play for effortless installs, but they’re also super easy as well as intuitive to use and configure!
