    Abstract: An apparatus and methods for effectively determining the start of combustion in a cylinder of an internal combustion engine where the start of combustion is calculated by obtaining cylinder pressure data (P), processing the cylinder pressure data (P) into a processed pressure value indicative of the occurrence of SOC, comparing the processed pressure value to a predetermined threshold value, if the processed pressure value crosses the predetermined threshold value, determining that SOC has occurred, and calculating a crank shaft location at which the predetermined threshold value was crossed by the processed pressure value thereby identifying the crank shaft location at which SOC occurred. In alternative embodiments, optional steps may be provided including a verification step, a windowing step, a filtering step, determining occurrence of misfire, and determining occurrence of retarded timing.

    Abstract: A constant horsepower throttle progression control system and method. In order to improve driveability of a vehicle compared to prior art engine controllers, the present invention operates an engine so as to either produce a constant (or nearly constant) output horsepower at all engine speeds for any throttle position, or so as to produce an output horsepower equal to a predetermined percentage of the range between full rated power and motoring horsepower at all engine speeds for any throttle position. The predetermined percentage may or may not be equal to the percentage of full throttle represented by the throttle position, and may or may not be linearly related thereto.
