The ecu files are different because the bins are different.  A MAF bin
has different tables than a MAP bin does, manual is different from
automatic, and code changes from year to year also move tables around. 
The .ecu file specifies where in the bin various tables can be found,
how they're scaled, what the data values are, etc.  With .ecu files, one
generic editor can be used for any bin file because the ecu file tells
the editor where to look to find tables.

efi332 is a project to build an EFI computer from the ground up,
including original software.  see the WWW page for more info,

None of those, but learning to read 6811 assembly wouldn't hurt.  By
reading tuning tips and programming 101, searching around in the
archives for answers to specific questions, and especially looking at
some of the bins on the ftp site with some of the free editors you'll
begin to see how tables are laid out.  If there's not a .ecu file for
your bin, you can use this knowledge to start finding tables in your
bin, and create a .ecu file from there.

Depends on what you want to do.

That's a good question.  I just added it to the FAQ, look at the main
gmecm page (www.diy-efi.org/gmecm), click on FAQ.
