RE: fuel injection

[<keej@xxxxxxxxxxxx>]

I don't believe this would work. I've been reading a fuel injection concepts
book and what you describe sounds somewhat close to the early 1930's
Mechanical fuel injection systems and they didn't work anything. There's too
many variables that the computer helps to control, and too many little
things that the carburetor system does through many magic little moving
parts to make everything work. Pick up a fuel injection book at the library
and start reading through everything. Un-mystify all of those "damn sensors"
and become familiar with what each one does and you'll find that
fuel-injection is really simpler than you would think... I still have alot
to learn before I start reprogramming them, but that is my goal so that I
can start intalling EFI's on my boat, wagoneer, etc. I have already
retrofitted a Chevy motor with a TBI setup, but on that one I could use the
factory PROM without any fuel curve mods so it was pretty easy...

Later,

Subject: fuel injection


ok guys i have an idea, and i'm not so sure how easy it would be to set up
but... here goes, gotta be easier than dealying with all the computer crap
baisicaly what i want to do is take the intake manifold off of a 4.0  and
set it up without a computer
as i understand it with fuel injection you have baisicaly a pressureised
loop coming from and to the fuel tank, along with this is another line that
comes up to the injectors, in between the two is a reastatcontrolled by the
computer and as the throttle is increased <among all sorts of other
variables.. .but this is the important one> the reastat closes a valve off
and forces the fuel to move on to the injectors, wich are open.
now, if one was to remove the computer, and reastat, and replace them with a
manualy controlled one, that you could hook up to say... a throttle cable it
could do the same job, only without having to mess with all those damn
sensors and wires and crap, and most importantly at a much lower cost.

what do you guys think is this totaly out to lunch or with some refinement,
great fun?
