Audi 2,2T AAN engine

Now with orginal trigger

ECM: 3.3 #332

Modified to accept auditrigger

Scope messurements are done at ~200rpm

• 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? Noise is from primary trigger /Emil_M
  • [Pic_2]
• added blob at SJ7
  • also scope here to see the signal mix from distributor and sec lm1815 output.
  • [Pic]
  • This picture is over longer duration, peak is when i hit startbutton[Pic]

also try to take a log with distributor unplugged, you should see 0x0A for each secondary trigger
