Abstract
A parameter, such as oil pressure, is repetitively sampled along with indications of speed, such as clock counts from a flywheel tooth counter, the parameter value and speed indications being stored and retained through at least several samplings, the parameter samplings being analyzed to find one of interest, the related speed indication thereupon being converted into speed dimensions for use. Specifically, oil pressure and engine speed indications are simultaneously sampled and stored, being retained for several sampling intervals, successive pressure readings are compared to find the knee in the curve of oil pressure as the pressure regulator begins to cut in, the pressure ultimately determined to be at the knee and the related speed indication being brought out for use, with conversion of the speed indication to rpm dimensions.
