TTS recently posted a tuning manual on their website that provides a lot of information on EFI tuning. For those of us who may not know much, if anything, about what the big deal is about getting a good tune, or what the tuner is doing to our bike with his computer, check the table of contents of the manual and get acquainted with your bike's EFI system.
While the pictures of the tables are from TTS' tuning system, the basic information about the ECM, look-up tables, VE, etc. are useful to our HD EFI systems (at least the Delphi EFI).
The tuning manual is probably more information than I would need, but very informative nevertheless.
