The Power Commander is a fuel injection adjustment unit that plugs “inline” with the bike’s stock ECU (electronic control unit). The PC uses original equipment style connectors, so no splicing or cutting of the harness is required. Most installations take less than 15 minutes, some as little as 5 minutes. Changes are made to the bikes fuel and, in some cases, ignition curves via the PC’s on-board microprocessor. Using this technology we are able to offer a large area of adjustment without making any permanent changes to the bike’s ECU. Removing the PC returns the bike to its previous stock condition. Each unit comes complete with software and cable link that allows you to change between different maps or make adjustments to a map file.
