Abstract:
1. A method of calculating average revolutions per independent unit in a vehicle comprises the steps of: (A) providing an engine, wherein the engine includes a sensor and an engine control unit (ECU); (B) detecting a plurality of engine revolutions with the sensor for a designated time period; (C) sending, timestamping, and recording each of the engine revolutions with the ECU; (D) counting the plurality of engine revolutions with the ECU in order to determine a total number of engine revolutions; (E) retrieving a current odometer value from the ECU during the designated time period; (F) calculating a final value for average revolutions per independent unit with the ECU by dividing the total number of engine revolutions with the current odometer value; (G) sending and displaying the final value with a control panel of a vehicle; providing an outlier value for average revolutions per independent unit; displaying a warning notification for odometer tampering on the control panel, if the final value is greater than or equal to the outlier value for a predetermined time period; and sending the plurality of engine revolutions into an external computing device with a communication mean in order to graphically display a timeline graph for the plurality of engine revolutions.
