Thanks much, Malcolm. Now if Steve would just move it to the readable
directory... :p
Now do you or anyone else have any suggestions on where to start with
creating a schematic from an undocumented ECM? I'm not familiar with
the processes of going from a board to a schematic. The ECM I have here
(16132240) is extremely similar to the 8331, except that it uses some
odd chip instead of an IAC driver. Sequential V8, lots of I/O...
Perhaps the biggest difference is it's cheap and in junkyards everywhere.
Thanks,
Ryan

ftp://ftp.diy-efi.org/incoming/01228331.zip
Contains a 3 page schematic of the ECU (incomplete), and 6 pages of scans from the workshop manual with the pinout usage in an Lotus Carlton.
I do have a full wiring loom diagram for the LC, completer with connector and pin part numbers, but it's approximately 3 feet tall and 8 feet long. Not sure how to scan that - it's almost like a roll of wallpaper.
Cheers,
Malcolm
PS Sorry about the format of my posts - I've set everything to plain text, but my ISP doesn't seem to understand!

The incoming directory is world writeable but not readable, in order to
prevent the bit torrent types from filling it up. Upload it to
incoming, send a note to the list with the filenames and descriptions,
and I'll get them moved over to the "uploads" directory, which is
readable but not writeable.
