Terry,
I knowledgeable friend of mine suggested a cheap basic fuel injection system
to work with. He suggested using a throttle body injection system off a
mid-80s GM car. You could buy the whole system, fuel pump, wiring,
computer, and all for several hundred dollars. There is plenty of
technology available to burn chips on a laptop. It would be a single fire
system of course. Hard part would be cobbing up an intake manifold. But
again, the GM manifold baseplate could be the start.
Regards,
Rey
