Larry, what I think you want to do is build an experimental aircraft with a 
digital dash.

One of the best ways I can think of is for you to go to automationdirect.com 

If you use some of their new touchscreen panels for use as a display and 
possibly control of noncritical functions, and use a DL250 plc as a data 
gatherer, you can attatch any type of analog or digital input or output 
device. such as speed, direction, pressure(altitude).  Even G-force 
accelerometers on a chip for about 20 bucks.  It even has closed loop so it 
could control cabin pressure, for example.  It even has a high speed input so 
you could use it to measure RPM, or schedule service reminders.  You can make 
the software meters look anyway you want, and can use imported graphics to 
show visuals of wheel and flap condition for instance.  Without an interface 
module, you can only run one toughscreen at a time, though. You could even 
have it do datalogging as a black box function. You would probably have a 
couple of grand in it by the time you are done. Although it would be capable, 
I would not use it as an engine controller on aircraft.  Either use Subaru 
Injection, or 2 BMW/Bing altitude compensating carbs.  Automation.com's stuff 
is highly reliable, we use them at philips for mission critical applications, 
and all of their manuals are on line.  Please call or email me if you want 
more info.  These units could also be used by anyone who wants to have a 
totally integrated vehicle dash and control box.  Run your HVAC, windows, 
step up that second fuel pump under boost, run an elctronic transmission, 
make a cool visual of your vehicle, etc.


Thanks for listening to my electroyappin!
