    Abstract: A system for controlling operations of an engine comprises a plurality of cylinders and a controller operatively coupled to each of the plurality of cylinders. The controller is configured to determine an operating condition of the engine, and in response to determining that the operating condition is suitable for activating less then all cylinders of the plurality of cylinders during a cycle of the engine, determine a first firing pattern, and a second firing pattern different from the first firing pattern for activating the plurality of cylinders of the engine. The controller is configured to activate a first set of cylinders of the plurality of cylinders based on the first firing pattern, and subsequent to activating the first set of cylinders, activate a second set of cylinders of the plurality of cylinders different from the first set of cylinders based on the second firing pattern.

    Abstract: A method of calibrating a control system based on a parametric value of a component. The method includes receiving a current from a component of the control system. The component is communicatively coupled to a controller and has a parametric resistor with a parametric resistance value correlating to a parametric value associated with the component. The method further includes determining the resistance value of the parametric resistor by measuring a parametric voltage rating from the current. The method further includes mapping the resistance value to the parametric value associated with the component. The method further includes generating a calibration data set. The calibration data set is based on calibrating the control system to calibrate for the parametric value. The method further includes transmitting a signal to the component. The signal is based on the calibration data set and is configured to calibrate operation of the component.
