A while back, we built a little circuit that worked similar to this, but
worked slightly different as follows.

A signal from an injector (Banked mode) started a timer, which had its
time base adjusted by the amount of boost.
Below a certain amount of boost (<.5psi) nothing happened. Above .5psi
the extra injectors were actuated.

As more boost was added, the extra injectors came on longer. The extra
fuel curve followed a linear 'curve'
which was set by a pot. Not very hi-tech, but it worked VERY well. If
any body is interested, I will release the circuit diagram.
