Could it work?  Of course it could, given enough development.

Nit picks:
I see no redundancy.

It's still pretty basic and I see no implementation of ignition timing
optimization (important for best economy).

Oh, Wait, I see no ignition at all, where is it?  or are we waiting for the
soon to come 555 ignition system?

Requires modifying or replacing the crank sensor trigger wheel.


Paul has obviously built one of these things, why can't he tell us how well
it works?

He said it best in the following excerpt from his web page:

"  I can not guarantee this system will work as well as Klaus's [more
complex 555 EFI] system as the *devil is always in the details*. "
(emphasis mine)

Somebody build it and try it so we'll know.

Tracy
