Power Commander Fuel Controller (PCFC) Product Introduction Inexpensive yet very precise way to control your fuel curve. The Power Commander FC is a new plug-n-play fuel management device pre-programmed with Make/ Model specific maps. In addition the Power Commander FC has the added ability to modify or change these maps on the fly without a computer. Users can literally select between a Power Commander FC Map, custom-built maps, or even fine tune low, mid or high rpm ranges while sitting on the bike and without plugging into a computer. Standard +/- 10% increments from selected map settings, different ranges are available using the supplied Control Center software. Users can also load up to 10 of their personally built Power Maps into the Power Commander FC and select between them while in the saddle - eliminating the need to "re-boot" with the computer every time a new map is desired.

A Note about maps: Dynojet does not provide pre-developed snow machine mappings in our Power Commander devices thus shipping them with a zero map, and customers are instead more well-served by the aftermarket performance package specialists/our tuning dealers that generally have specific maps developed for their various performance packages. Further, Due to the lack of standardized performance setups on the sleds many customers also find that using our Auto Tune system in conjunction with the Power Commander gives them the capability to get their particular sled and setup tune dialed in perfectly no matter what modifications they currently have as well as being able to change and adjust the tune to accommodate any future modification they may choose to make as well.
