A multi-cylinder internal combustion engine is operative in a controlled auto-ignition combustion mode. The operation includes monitoring engine operation, and globally adapting fueling for all the cylinders based upon an engine intake mass air flow and an air/fuel ratio. The fueling for each cylinder is individually adapted based upon states of a combustion parameter for all the cylinders.
