[s-cars] Knock sensor output and stock audi connectors sourse?

[Trevor Frank]

First, I haven't even looked at this, but



What signal is sent or broken by the knock sensors, I am thinking that
it might just be a 5 volt logic/digital?  Ok so if it is that simple
anyone know what pin?  I need to look at the Bentley to see if it shows
the pin outs.  If it is as simple as a 5 volt digital then it I suspect
it would be easy to also adapt it to a light on the dash or at least to
log it.  If it is some kind of varied analog voltage then I could still
data log it.



Also anyone know of a source for the stock audi connectors, or the pins?



I would really love to log when the knocks are being triggered on a data
acquisition system that I am using.  It would be very cool to put in
connectors between the sensors so that I could make a generic wiring
harness that could just plug in and out, currently I am just cutting
into my stock harness.



Here is another question, why do our cars ping, what is it with the
knock sensors that aren't working as it should?  Or is knock sensing
really worth much at all?



Oh ya and for those interested I found a clean signal to the coils on
the communication wire to the pos, the coil side was a bit dirty so it
couldn't be used.  The cleanest signal was from the cam position sensor
but it was going to be a bit more difficult to tap into.
