Abstract
An electronic turbocharger control system for an internal combustion engine is provided to control at least one turbocharger by controlling a bypass valve and a wastegate in response to the engine speed, engine load, ambient temperature, and the operating environment's barometric pressure wherein the turbocharger is controlled to operate within predetermined islands of efficiency on a pressure ratio versus mass airflow map thereby allowing the adaptation of one turbocharger assembly for various applications. The method and apparatus provides improved engine efficiency and increases low speed torque.
