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
