Here my take on the whole cam timing, ignition computer thing.
Having spent two years wrestling with my MAC-02 timing, I think
I may have a clue. The very narrow window you mention (2 degrees)
seems to only be in effect during starting. Once the car is going,
the computer can handle LOTS of variation (+/- 15? degrees as per
Audi Tech Notes) Anyhow it's pretty huge window. Problum is, you
have to set it back to zero when you try to restart. I think a
centrifugal cam would do that. Question is, does the timing of the
ignition move with the distributor pulse? I am almost sure not.
It is just used to detmine which of the three flywhell pulses is TDC.
So it sounds to me like it is a bolt on mod. Did somebody say how $$$
this was, Mr Googin, perhaps?
