Timing: Shows the beginning of the EMM pulse to the fuel injector in degrees BTDC or ATDCFuel Pulse Width: Time duration
of EMM pulse to fuel injector; measured in millisecondsBarometric Pressure: Indicated in Inches of HgThis data allows EMM
altitude compensation SWITCHES S In S.L.O.W.t: YES or NO: YES means engine is in S.L.O.W.t modeThe water temperature sensor
reading can verify this conditionGround the water temperature switch lead and watch this value change when engine goes into
