ABSTRACT:
An engine management apparatus for an internal combustion engine of a vehicle includes a microprocessor that is operable on adjustment mechanisms of the vehicle. The vehicle has a torque sensor for sensing torque generated by the engine and the adjustment mechanisms adjust parametric values related to the torque. Memory circuitry is accessible by the microprocessor. The memory circuitry stores data representing at least one set of parametric values and a range of torque values corresponding to respective parametric values in the set. A set of instructions are executable by the microprocessor so that the microprocessor cyclically retrieves a real time torque value from the torque sensor and updates the memory if the retrieved torque value is higher than a stored torque value corresponding to a current parametric value. The microprocessor adjusts the current parametric value if the retrieved torque value is lower than the stored torque value.
