An engine control system configured to operate an engine is configured to predict an expected duty cycle including an expected demand from the engine, and calculate two or more future operating conditions, each future operating condition including engine control parameters that, when used to control the engine, are expected to result in the engine meeting the expected demand. One of the future operating conditions is selected, and a present operation of the engine is adjusted in response to the selected future operating condition. A vehicle and/or offroad diesel apparatus may comprise the engine control system.
