Power Commander Fuel Controller (PCFC) 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.
