Summary of change:
'''Audi S2 ABY Engine''' See InputTrigger/AudiTrigger '''Trigger''' with OscilloScope please measure * 360 crank degree "crankhome-VR" (measure amplitude also) * 720 crank degree Cam-HALL window (with 10k pullup to +5V or +12V) ** relative to each other Trigger related EC36 pins: * '''EC36/26 - GND''' * '''EC36/27 - Primary Trigger VR''' (135 pulse) ** measure resistance to GND * '''EC18/12 - secondary trigger "crankhome-VR"''' (1 pulse / 360 crankdeg) ** measure resistance to GND, and scope signal * '''EC36/13 - Secondary Trigger cam-HALL window''' (1 window / 720 crankdegree, around the "crankhome-VR") ** (use 4k7 .. 10k pullup to +5V or +12V if ECU is not connected, otherwise DVM or scope would show 0V) * '''EC36/28 +5V needed if ECU not plugged in, ECU supplies 5V for HALL sensor via this pin''' Note: If ECU is plugged in, and cam-HALL operation is uncertain (no scope to measure ???) then as a debug-experiment * '''cam-HALL signal''' (at cam-hall female connector, pin which is connected to EC36/13 , please verify) '''connect to GND''' (0V) so that cam-HALL inverter inside ECU will invert to 5V (logic high) inside allow through the sectrig VR ** capture InputTrigger/TriggerLog ** rename triggerlog file to note if camHALL_grounded or camHALL_connected and publish file ** depending on divider, assuming divide by 3, in triggerlog 45 pulse seen out of 135 crankpulses ---- '''Grounds:''' * See GenBoard/Manual/GroundConnections [http://www.vems.hu/files/AudiAbyLedenyak/ Trigger info from customer (jpg, wav)]
