Blown 350 with 1227730 ECM

[Bill Shaw]

There IS a commented disassembly around,  but the owners aren't sharing.  Turbo_P4_Doc.pdf  is on the FTP site.  (ftp://ftp.diy-efi.org/incoming).  While you're there you might want to pick up a copy of   SYPROM.EXE ,  which will take a '749 bin and list
most of the important tables and data in it with the addresses.  There's also a section of the site with a bunch of '749 info.  Go to the main page and follow the links to the ECU info.

hth,

Bill
