We've had discussions about improving the Audi ignition system on this
mailing list a while back (almost two years ago). The bottom line from that
discussion agrees with Glen's assessment that the Audi Bosch ignition systems
are pretty good as they are and are hard to improve upon. I located the
relevant articles from that previous discussion; one is included below.
I have others that I can email directly to the person interested in adding
the Jacobs system if you let me know your email address (I can't tell who
the originator of the email is due to my mail reader and the way this mailing
list is set up).
