Dual TBI units

[Mike Swayze]

the reason I expressed my $.02 on the
subject was for a reason.
progressive linkage  would work similar
to the cam on a carb setup(flow
velocities and what not-- I haven't seen
it yet but somewhere in the archives
there is supposedly a thread that has
the reasons for progressive
linkage.)--as I understand it--the
throttle does not open linearly ..
hooking the tps to the linkage allows
you to use one tps((one set of
sensors--one ecm etc. etc.) ..the extra
set of injectors would just be piggy
backed onto the existing
ones(parallel?serial?). I am still
learning about P-H vs SAT injectors. If
I understand it correctly Saturated
injectors draw more current than Peak
and Hold((somebody correct me if I'm
wwwrong((see add.fuel.inj.zip)))) Of
course the fuel curve would need to
be"tuned"((see programming 101)) for the
additional injectors.Some of the other
list members may have  specific
recommendations as to which tbi throttle
bodies use which injectors(I don't
know). I am assuming a '747 or '165 ecm
could be used.
whats 4-bits (a $.25).
