Controlling automotive vehicle powertrain, drivetrain suspension components and accessories using portable personal electronic telecommunication devices

The circuit controls powertrain, drivetrain, vehicle suspension and accessory components of an automotive vehicle to programmatically provide different drive and handling performance using a portable personal electronic telecommunication device having memory and a processor. The circuit includes a protocol converter circuit coupled to receive electric power from an electrical power system of the automotive vehicle, and has at least one port to electrically couple to at least one actuator that supplies control to the controlled component of the automotive vehicle. The protocol converter circuit provides a communication channel by which communication is established with a portable personal electronic telecommunication device. An executable program stored in the memory circuit and operated by the processor of the portable personal electronic telecommunication device supplies control signals via the protocol converter circuit to the one or more actuators, thereby programmatically providing different vehicle drive and handling performances. nc u ±~ 0j ---
