I'm curious, since you obviously have done a great
deal of testing and implemented workable solutions
using both the MS I and II hardware and runtime:

How much of a difference does injector timing make at
idle?  And in practice, where did any differences show
themselves?  Obviously, if you have a really big cam
and idle is very "lope"-y, with a lot of intake
reversion and charge dilution with exhaust gases,
you're going to make things a little more tolerable at
idle by using timed sequential injection, but I have a
sneaking suspicion that there is a small but
noticeable difference at idle, and possibly at small
throttle opening cruise (high gear, low road speed). 
If you've previously made this info available
elsewhere, just point me at where I can find it; I
don't want to make extra work for you.  You sound like
a damned busy guy!  ;)
