Trigger setup for Audi S4, 5cyl Direct Fire engine
Audi 2,2T AAN engine
Now with orginal trigger
ECM: 3.3 #332
Modified to accept auditrigger
- added lm1815
- added 100k resistor at R182
- added wire, ec18pin12 to R90
- measure at lm1815 pin3 that this signal comes through (with scope)
- [Pic] I think this signal is inverted, try change polarity. The interference between the triggerpulses, can you zoom in and tell if it is from the crank teeth or just normal noise?
- added blob at SJ7
- also scope here to see the signal mix from distributor and sec lm1815 output.
