Welcome to the EFI-332, DIY-EFI, and gmecm WWW pages.

  • There is now a TWiki installed for the diy_efi and gmecm lists. A TWiki is a WWW page that can be edited easily by anyone, right from within their browser window. This is to allow YOU to be able to add your own information to the WWW page for others to see. Did you figure out something that's been puzzling you for a while? Got a new project? Want to post about your vehicle? Got a new disassembly hack? Find something interesting in the archives? Got a contribution for the FAQ?
    Post it on the TWiki!
    That's what it's for. The 400+ members of the list together can do a much better job of keeping things up to date collectively than I can alone. There is no log in or registration required, just click on the "Edit" link that appears on the bottom of each page and have at it.
  • This is the home page for the mailing lists of the same names. The DIY-EFI list has been in existence since May 1994, and is for discussion of all aspects of electronic fuel injection, engine management, and related topics.
  • The EFI-332 list is a companion list that was begun in March 1995. It is specifically for a group project based on the MC68332.

  • The gmecm list was begun in Feb 1999. Its purpose is to understand the operation of GM ECMs in great detail. Topics include finding table locations in the EPROM image, and disassembling and understanding what the stock GM code does.
  • Please consider donating to help keep diy-efi.org running.
