above 1600 rpm the fuel pulsewidth is minimized as shown as point 20 of fig2 similarly when the pedal position is nearly closed pp 0 05 and the engine is operating above 2000 rpm the fuel pulsewidth is minimized as shown at point 21 the difference between the minimum fuel pulsewidth value for the various pedal positions i e between points 20 21 and 22 allows for engine braking modulation in this example the more pedal deflections the less engine braking desired similarly the regions 23 24 and 25 correspond to the maximum fuel pulsewidth for near idle conditions beyond a certain pedal position such as pp 0 3 the fuel pulsewidth is preferably maximized to allow for the greatest amount of torque this is shown in fig2 as line 28 from the foregoing graphs illustrated in fig1 and 2 a relationship can be seen between accelerator pedal position and fuel pulsewidth from which an effective engine output monitoring scheme can be created referring now to fig3 there is shown a schematic diagram of an internal combustion engine 40 and associated powertrain control module 42 as well as an operator interface 68 in accordance with one embodiment of the present invention the engine 40 includes a plurality of combustion chambers 41 each having an associated intake 43 and exhaust 44 operated by respective valves 45 46 combustion occurs as a result of the intake of air and fuel from the intake manifold 47 and fuel.
