NumberOfCrankTeeth
Tip Strip: Number of crank pulses per rotation
Units: pulses
Detail: Specifies the number of teeth on the crankshaft trigger wheel as if there were no missing or extra
crank teeth. For example, a 60-2 crankshaft pattern would have
this is the pulses per revolution.
NumberOfMissingTeeth
Tip Strip: Number missing adjacent crank teeth for the gap. M = 1 or 2.
Units: pulses
Detail: Specifies the number of missing adjacent teeth on the crankshaft trigger wheel for an
type. For example, a 60-2 crankshaft pattern would have
applicable for N-M pattern
Plus1Location
Tip Strip: Plus1 tooth location with respect to mid-point
Detail: When Advance, the EPT is configured to look for a Plus1 tooth which is advanced from the mid-point
between two evenly spaced crank teeth. An advanced Plus1 tooth should be advanced from the mid-point
by approximately ¼ of the normal tooth spacing. When Retard, the EPT is configured to look for a Plus1
tooth which is retarded from the midpoint between two evenly spaced crank teeth. A retarded Plus1 tooth
should be retarded from the mid-point by approximately ¼ of the normal tooth spacing. This parameter is
only applicable for Plus1 pattern types.
EngineSpeed
Tip Strip: Indicates engine speed
Units: RPM
Detail: Engine speed output from the EPT function.
