[DML] Re: Fuel Metering

["David Teitelbaum" <jtrealty@xxxxxxxxxxxxx>]

The auto manufacturers went to fuel injection to improve fuel economy
and reduce emsissions, especially during the warm-up cycle.
Carbureated cars always had warm-up problems and cold driveability.
Difficult to properly atomize fuel especially with the cooling effect
of the venturi. They started with mechanical injection systems, moved
to hybrid systems (like we have on the Delorean) and have gotten to
full digital control. I agree that the system on the Delorean is NOT
fully digital and it can be improved by removing it and replacing it
with a true, fully digital fuel injection system. Not going backwards
to a carbureator. The tiny improvements gained by spending a large sum
of money to replace the fuel system makes no sense. You are correct in
that the main thrust of this group is to try to keep and maintain the
Delorean in as origional condition as is possible. Some things can
(and need) to be improved like the electrical system. Other things
such as the fuel system are fine and can be made to operate very
reliably without wholesale replacement. I (and many I guess) like to
hear about improvements and modifacations owners make to their car. I
find it interesting and in some cases useful. That's how we make the
car more reliable and safe. To advocate that everyone should rip the
K-Jet off their car and put a carbureator on is not necessarily the
"best" advice for a majority of the readers of this list. For one
thing not everyone is as talented as you are and are capable of doing
this kind of work. Another problem is ongoing support and maintaince.
None of the vendors would touch such a modifacation with a ten foot
pole! Their first impression would be to remove it and go back to
stock. Mark Levy changed his motor. I don't hear him saying everyone
should pull their PRV and stick something else in. Dave Dellman pulled
his motor and went electric. I don't think many will choose to follow
his lead either. The point is neither are advocating their mods. They
tell us about it for our information. As for making major changes to
the car, the farther you stray from the origional car the less it is
worth. This is not my opinion, this is the market forces and Deloreans
are not immune.
