As I recall, the processor was a 16HC11.  It was reading intake
     manifold pressure and engine RPM, controlling four fuel injectors, and
     controlling the timing for the four spark plugs.  It was programmed
     for idle speed control and to provide maximum power when the throttle
     was opened above idle.

Last year Circuit Cellar magazine ran a series on making a
controller for automotive engines.  I'm not sure of the issue
numbers but, I give there url:

As I recall they did not use a pic though, they used a controller
designed for the purpose.
