  • The Dummy's Guide to Direct Ignition & Coil-Packs etc

    I put some midnight oil into this document to get things started... You will see I have more to do, but I would happy to get some feedback from folks on the usefulness of this kind of document.

    It's a little more wordy than I had originally intended but that is nature of the beast. I hope it is useful info for people - even if they cannot understand all of it.

    Next part is to capture some real world signals, verify the theory and confirm the location of the dwell table in the ECU... all subject to getting some quality time in the garage !

    Fantastic work Paul. On a very quick read through, I only caught one error: The UrS4 V8s do NOT have direct coil ignition. I have a 94 S4 V8 avant with the ABH V8 and it has two distributors and two coils and 8 distributor to plug wires. I don't think there was coil on plug V8s until the A8 (and the S6 plus ABK).

            Hello Paul,

            I gave the document a quick glance and it looks spot on.
            When I'm off later today I'll give a thorough read.

            I was going to say that I'm missing Fault diagnoses and the modern wire loom and 2.0 TFSI coilpack upgrade, but I can see in the table of contents that your already planning to add those.

            Please keep up the good work!

              nice info paul
              but like VagOrBust say,maybe it's handy if you give some extra information about how to convert the origional coils to tfsi coils with a wirediagram,partnumbers and dwelltime

                  There is a lot of coil info in these posts of mine:

                      Minor correction: ABK is the 2.0E 4 banger used for example in my 80 Avant. The S6 Plus had the AHK.

                          I just read the whole thing and must say great work. I am always appreciating someone taking his time to create something that at the end helps hundreds of people

                          Great work
