It's been done.I,ve got the pulse generator sitting on the kitchen table
right now - it fit in the speedo cable, at the trans gear end. The carb unit
used the flow sensor I just shipped to garfield - the EFI unit used a "black
box" that connected to the fuel injector wires.
The "computers" got stolen out of my two Toyotas one New Years Eve quite a
number of years back. The name was CompuCruise, and they worked well.
