A method of correcting engine performance in response to assembly deviations includes the steps of measuring the physical characteristics of each cylinder of the engine, and storing the resulting data in the associated ECM. The engine is then operated in accordance with the stored data. The physical characteristics that are measured include, inter alia, a distance of axial displacement of each piston within its associated cylindrical bore; a timing characteristic of the camshaft; a timing of a fuel injection interval; the rate of fuel flow as a function of crankshaft angle of rotation, and a timing characteristic of the crankshaft. Some of the operating parameters that arc controlled during engine operation in response to the data stored in the ECM include, inter alia, the air:fuel ratio and the timing of a fuel injection interval for each piston. These corrections result in increased power, decreased emissions, better mileage, a smoother running engine, and less costly components.
