Very well said David. "Quaint" is one word but not the one I'd use. A
modern vehicle combines all those functions including idle speed, ESA,
Lambda trim, on and on, into one box. Most are also adaptive learning
systems that compensate for engine and component aging. There is zero
maintainance and reliability is an established fact. Add in the OBD
functions and it's a no brainer. Look at the Toyota TCCS for example.
It's a marvel of engineering and a more intelligent system can't be found.

What you suggest is not all that difficult to do. At the very least a
MegaSquirt or similiar system could easily be installed on a Delorean.
It's low cost, adaptibility, use of off the shelf sensors, and open
architecture for programming make it a good choice. Add in DIS and
you'd have a great setup. Not that the K Jet is all that bad to begin
with. It's easy to work on, simple to understand, and very reliable.
(I do note a lot of misunderstanding and confusion regarding the
mixture trim system however).

As far as emissions the PRV would perform better with less drivability
issues, better fuel economy, and improved cold weather operation with
 EFI. Even TB EFI would be an improvement. Why anyone would carburate
a PRV is beyond me, it's a giant step backwards in every respect. I
have to assume they'd do it solely because they lack the skill or
motivation to learn anything new. Either that or they like working on
the car more than driving it.
