ABSTRACT:
A system for interfacing with the ECU of an automotive vehicle for optimizing engine control to meet emission requirements or engineering targets for catalytic converter systems includes a secondary controller and an emission analyzer. The secondary controller monitors sensor input to the ECU and actuator output from the ECU so as to mimic an ECU actuator control function by generation of an operating parameter control map(s) functionally identical to that used by the ECU. The emission analyzer receives vehicle sensor input and additional emission data from a bench gas analyzer to similarly produce not only the parameter control map but also emission maps correlated to the operating parameter control map which are systemically changed to optimize emission conversion by the vehicle's catalytic converter system and modify the operating parameter control map. The modified control map is inputted to the secondary controller which bypasses the ECU to control the actuator function in accordance with the modified control map. Emission maps are subsequently generated and the modified control map further modified until conversion of emissions by the vehicle's catalytic converter system is optimized. The system permits engine control to assure emission regulation compliance without knowledge of the ECU's code while also providing design optimization of the catalytic converter.
