I may be wrong about this, but I think it's the firmware in the PC that's different. The maps may work. I uploaded my map on the Dynojet site if you want to give it a shot. It's in the user submitted section and is for Arrow slip-ons and open box w/K&N filter. Works for me. Each bike is a little different though and none of the off-the-self stuff really worked for me. The real benefit of the Power Commander was realized when I had the map built.
