The Dynojet Power Commander plugs inline with your bike’s stock fuel injection system. It uses OEM (original equipment manufacturer) style connectors making installation easy and quick. The Power Commander III USB allows a full range of fuel adjustment, as much as +/- 100% over stock. Adjustments can be made either with a Windows based computer or by using the face plate mounted button adjusters. No permanent changes are made to the bike’s system. Once the unit is removed the bike reverts to its stock settings.
