There are a lot of those (analog open loop) ECUs 
still around.  They use high side injector drivers, 2 
banks.  Trigger one bank per crank revolution.  I 
thought throttle body were saturated injectors.  

I did have some luck last year, reshaping a 
saturated (low side) drive signal into a peak and 
hold waveform.  Needed it, because my ACCEL 
VII isn't set up for p + h injectors, in spite of what 
they claim.
