Did someone say this was the pulsewidth meter project on the DIY page? 
That's mine (warts and all).  The input to the circuit is a bipolar
photocoupler, I thought this would simplify connecting the circuit to
the injector (No worries about which side to connect to, if the injector
is driven on the high or low side, etc.).  Just connect it across the
injector and off you go.  Maybe not optimal, if someone wants to give
comments I'd like to hear them.
