486 EFI Computer

[Frederic Breitwieser]

Just to re-illustrate my point that the hardware is less critical, 
consider using a Nintendo Color Gameboy :)

If you scroll further down the page, you'll see that the "Shell Mileage
Marathon Engine Management System" is a project underway with this
particular interface.

Also, I ran a low-member count "simpleefi" list for a while where we
were discussing the merits of using a 555 timer or PICs for EFI.  Its
entirely doable.  Its not easy of course, but its doable.  Same with a
PC.  Totally doable, no problem.  Interfaces are available for almost
anything, its all in the code :)

Have you ever opened up the Electromotive Tec II EFI system?  I ran my
test twin-turbo Buick V6 on that for a while, and when I opened it, the
part count was very low.  Same with the Haltech ECM6A.  Its a box with a
few chips and some support parts, fancy connectors, and really slick
code.
