ABSTRACT:
An electronic control (18) for a combustion engine that forms a portion of an automotive vehicle powertrain and has an output shaft for powering a drivetrain portion (14, 16, 17, 19) of the powertrain to propel the vehicle. The control has at least one ambient parameter variable input source representing a respective ambient parameter (EOT, BAP, AIT, and MAP) useful in deriving gross torque output of the combustion engine. The control also has at least one operating variable input source (EFC, ACD, DIT.sub.-- ADJ) representing a respective operating parameter useful in deriving a reduction in gross torque output of the combustion engine due to operation of the combustion engine, and a processor for processing a respective signal correlated to the at least one ambient parameter variable input source and for processing a respective signal correlated to the at least one operating parameter variable input source to derive torque at the output shaft of the engine for powering the drivetrain to propel the vehicle.
