Through Dynojet's Direct Injector Control, the fuel circuits on current models can be modified both richer and leaner than stock as much as -100% to + 250% in any particular area of the power spread with the PCFC. Also, up to 10 pre-programmed Power Maps are adjustable to your preference. Riders can literally select between a DFC Power Map, custom-built maps, or even fine tune low, mid or high rpm ranges while sitting on the bike and without plugging in to a computer. Standard +/- 10% increments from selected map settings, different ranges are available using the supplied Control Center Software.
