Nyet, I started this thread to learn some things about EFI. I stated what I knew about it in the first post which wasn't much really, i also asked if there were any books or other sources to look at other than s4 tuning wiki and no one has suggested something.
See the tuning sticky.
How will looking at Logs inform me on tuning processes and ECU (EFI) function? Not saying this sarcastically, I'm not experienced with logs really and would like to know.
Timing, fuel, boost.
From those three things, you can see what works and what doesn't. Log enough cars (preferably on the same dyno, same conditions), and you'll quickly get a feel for it w/o having to know ANYTHING about EFI.
At the end of the day, all tuning is about optimizing those three parameters safely.
Once you know your end goal, you have something to focus on when learning. Motronic is extremely complex, and like you said, it is easy to lose your way with so many things to juggle at once.
