Abstract: A power system is disclosed for use with a mobile machine having a work tool. The power system may have an engine, a first input device configured to generate a first signal indicative of an operator-desired output of the engine, a second input device configured to generate a second signal indicative of an operator-desired movement of the work tool, and a controller in communication with the engine, the first input device, and the second input device. The controller may be configured to adjust fueling of the engine based on the first signal and based on a desired speed of the engine during a first mode of operation, and to adjust fueling of the engine based on the first signal and a desired torque of the mobile machine during a second mode of operation. The controller may be further configured to selectively switch operation of the machine between the first and second modes based on the second signal.
