    Hello,

    does anyone have generalized schematics that show what is contained in an automotive EFI system and what is contained in a MEFI system?

    I've seen several verbal descriptions on this forum, but it seems that the answer varies quite a bit. I haven't found any good schematics online that show the difference. I'm looking for a flow diagram that shows the fuel flow and the electrical signal inputs/outputs (in my industry we call this a process & Instrumentation diagram, clever I know).

    Thanks

    Haynes Engine management systems, TechBook 3787, ISBN 1 85690 787 X. Basics, specifics, 3D graphs, sensor types, wiring details, more than you ever wanted to know about EFI. Don't ask me to scan it, there are 800+ pages.

    The Mercruiser and VolvoPenta manuals are pretty clear too.
