As i know..Power Commander is for motorcycle..there almost same like e-manage. The Power Commander is a fuel injection and ignition timing (on some models) adjustment unit that plugs "inline" with the bikes' stock ECU. The Power Commander (PC) uses original equipment style connectors so that no splicing or cutting of the harness is required. Most installations take less than 15 minutes, some as little as 5. Change are made to the bikes fuel and ignition curves via the PC's onboard microprocessor.
