The Power Commander Ignition Module is connected to the Power Commander 3 USB with it's built in expansion port link and communicates via a CAN interface. As in the case of the Power Commander, the Ignition Module uses OEM style connectors to plug in-line into the stock ignition harness so no cutting or splicing is required. The Ignition Module uses direct coil driver technology and allows a high degree of timing adjustment. The Power Commander Control Software allows the user is to advance or retard the ignition curve up to 10 degrees based on throttle position and RPM.
