As far as I know, it does.  This seems to be the compelling reason to switch
from batch to sequential port injection - better emissions under light
engine loads.  As Bruce said, once the injector duty cycle goes much over
25% or so, there's not a great deal of control over the timing of the
injector event relative to the intake valve opening/closing, so there's not
much advantage to sequential injector timing at this point.

Anyone else have a different take on this topic?
