This paper presents the results of using Computer-Aided Calibration (CAC) methods for engine torque mapping. Mapping was done in three modes: stoichometric, power enrichment and catalyst protection. The spark advance and air/fuel ratio were optimized to find the minimum values for best torque. The optimized variables were subject to the limits of the catalyst temperature and engine knocking. CAC methods are not limited to engine torque mapping calibration; they can be applied to on-line verification, parameter tuning and off-line analysis.
