Dynojet 15-025 Power Commander V Fuel Injection Module for Harley-Davidson Dyna Models 2004-2005 The New Power Commander V is loaded with tons of new features. Dynojet Power Commanders are one of the most efficient ways to get more power and performance out of your motorcycle with a reasonable price. The Dynojet Power Commander 5 is less than half the size of the older Power Commander 3 making it easier to install and find a place for it. The Dynojet Power Commander 5 is powered straight by the USB computer connection, no longer requiring a 9-volt adapter to program it to your motorcycle. A two-position map switching function is built-in for maximum flexibility in tuning, however the map switch is NOT included.
