Apparatus and method for two-step intake phased engine control system

An engine control system for use with an internal combustion engine includes a two-step switching device associated with each intake valve. The two-step switching device is switchable between a high-lift position and a low-lift position. A cam phaser is associated with the cam shaft and is operable to change a phase of the cam shaft relative to a crank of the engine. An engine control module is electrically interconnected with the two-step switching device and the cam phaser. The engine control module includes a memory. A computer program is stored in the memory of the engine control module, and is executable by the engine control module to conjunctively control the two-step switching device and the cam phaser dependent at least in part upon a desired engine load.
