There are many many ways a hobbyist could do this ... if you are serious, I
suggest you head down to your local college, discuss your intent, and get
yourself into the appropriate evening course(s).

If it was me, I'm thinking all the required leads come up front. There they
could be multiplexed by an appropraite analog to digital converter, read by
your program and displayed by your program. If it was me, I'd do up the
drivers in assembler with the application in Visual Basic.

I prefer the look of guages on board ... okokok ... except for my fishfinder
.... I won't even consider a car that has a digital dash ... but I can see
that digital could be a cost saver.

I've been wondering, what would be involved in having a computer interpret
and display gauge readings.

By this I mean something such as having a laptop receiving inputs from the
various gauge sending units such as oil pressure, engine temp etc. and
then
displaying them in some way.

I don't believe this is something I would actually do, it's just I was on
a
long drive yesterday and it got into my head and I would really like to
figure it out.

I've googled unsuccessfully (I'm ashamed to admit) so if anyone can point
me
in a direction ...
