In the spirit of a picture is worth a thousand words, I've added a block diagram of the Motronic MA 2.4. This is my interpretation from research, the data I've taken throughout this thread and some deduction. I believe it to be a good-fit, functional representation of how the Motronic does it's job as a fueling and spark computer. As I find errors, I'll correct the diagram. (e.g. I don't know if there is a cold oil temperature, spark timing adjustment.)
Next I plan to post other diagrams showing how the Wideband O2 mods of this thread affect the system, as well as diagrams of how the PowerCommander and Techlusion interact with the Motronic MA 2.4. Eventually I'll add all four diagrams with a PDF link.
