A technique for replicating information among host computing devices based on versions associated with variables of a state on each host computing device is provided. A method to control the powertrain includes monitoring operation of the powertrain, determining whether conditions necessary for growl to occur excluding motor torque and engine torque are present, and if the conditions are present controlling the powertrain based upon avoiding a powertrain operating region wherein the growl is enabled. Each signal transmission layer includes a plurality of signal conductors.
