ABSTRACT:
A system for determining and displaying a volumetric efficiency of an engine of an automobile includes an aftermarket display unit configured for installation into the automobile and a controller, the controller including a first memory configured to store calibration data associated with at least some of a plurality of OEM sensors of the engine and displacement data associated with the engine; a plurality of controller inputs coupled to the plurality of OEM sensors; and a controller output coupled to the aftermarket display unit. The controller is configured to execute program instructions to: read the sensor output; determine the volumetric efficiency based on the sensor output, the calibration data and the displacement data; and display the volumetric efficiency using the aftermarket display unit.
