Summary of change:
This engine has a custom 10+1 trigger (5 pins on crankwheel). Such installs are usually problemfree (and installer does not care to document publicly). This install involves some fighting for some reason, page created to summarize that (thematically, not chronologically). '''Primary trigger''' * VR, 5 pins on crank '''Secondary trigger''' * '''just HALL, 1 pin on cam (please confirm !)''' ** auditrigger, that is sectrig crankhome-VR masked by cam-HALL would be possible (same software setup) but over-complicated hardware (more chance for error) ---- Audi 5 cyl. 5 trigger references on crank. 1 cam signal. During cranking the [http://vems.hu/files/MembersPage/MikaelAudi/c010/ trigger log] looks really good with 10 pulses on primary and 1 on secondary but when it starts it gets "missing tooth" signals, too many pr tr and too less primary trigger. I've logged the two events. The setup is original for the engine and the sensor is VR. I'd took some pictures for you to see. Could it be that the crankshaft puts out the signal when the engine starts? Not impossible, but would be nice to see 2 occasions captured (a triggerlog and a vemslog also). '''VR trigger is primary candidate, check polarity (both primtrig and sectrig)''' at least with the DVM DC mode and "pull-away metal" method, or best with oscilloscope. The car was running with VIPEC before (same trigger?) and no problems, so it has to be in the ECU or maybe just some tuning problems? ---- coil option is good > Number of teeth = 10 > first trigger tooth = 0 > next trigger tooth = 2 > Angular width = 72 > Reference tooth (order of arrow) > 0 > 2 > 4 > 6 > 8 http://vems.hu/files/MembersPage/MikaelAudi/c010/IMG_0495.jpeg http://vems.hu/files/MembersPage/MikaelAudi/c010/IMG_0496.jpeg http://vems.hu/files/MembersPage/MikaelAudi/c010/IMG_0497.jpeg
