I´m doing an homecooked ignition system for my car. I got my hands on the 2002 make ignition coils(model: 06C-905-115-H) very cheap. I´ve found out the pinout for them, but cant find anywhere information about the control impulse, which should go from ECM through the pin 3 to amplifier. Does anyone know about the voltage of this impulse, and/or other characteristics? Please help!

PS. Perhaps are there out some fanatics of Audi who could even measure on their own Audi the signalform with oscilloscope ?

Here is the picture of one coil:

That is a coil for a 3.0 V6, is that the engine you have??

Im not really sure why you are making an ignition system, but im pretty sure its a 12v signal to the coil
but all of the step up voltage is done in the coil

 

engine idling = 1V/10ms wave form 32. Digital, DC, frquency modulated, readings from ECM pin 13 block B ignition amplifier

 

My engine is from year 1986 . The systems idea is developing my electronics skills, and getting rid of the ignition wires and distributor cap, which tend to cause some problems for old cars.

avant 80@2.6, i cant understand some of your text: what is this "wave form 32" ?

 

engine idling = 1V/10ms wave form 32. Digital, DC, frequency modulated, readings from ECM pin 13 block B ignition amplifier this would only be of use if you had the knowledge of the auto electrician, pulse 32 is a wave form on the oscilloscope which the electrician would confirm any problem with that electronic area, what you need to do is fit electronic ignition

#3 post was for the 1995 Ad 1.8T

 

This versioon A6 has only one ignition coil? What is this B5 pin for?

 

how many pins does your ignition amplifier have?? if 7 then pin 5 isn't used

 

There is no separate ign. amplifier, it is integrated into coil. The coil has 4 pins. I´ve made an picture to give an overview of its pinout. Perhaps can You describe the wave form 32 with an picture. I really dont know how it looks like.

I don't have a lot of data on the 1989, the wave form 32 is for a specific read out used by Audi ans is on their charts/data base so they have something to identify the wave but you need an Oscilloscope and its way too difficult for me to explain how its used, there are courses on it in college
