The present invention provides a method and system for systematically calibrating an engine misfire detection system for an internal combustion engine. The present invention provides a method of collecting a plurality of groups of sample data points. Each of the groups of sample data points represents a cylinder firing event. Optionally, misfire events can be induced during the collection of the groups of sample data points. Using the collected data points, a plurality of compensation parameters is then generated and applied iteratively to the sample data points to generally optimize the detection of misfire occurrences. Compensation parameters that produce a high accuracy misfire detection are selected and can be exported from the calibration system to transport to an engine controller in an internal combustion engine. Compensation of edge-to-edge error in engine speed data, engine noise, misfire signal magnitude, and filtering zone boundary coefficients enhance signal quality and further enhance misfire detection.
