I feel like I'm way over my head here, but would it be possible to have the 'setup'
of parameters done on a PC and downloaded to the unit which would then simply scroll
up and down displaying 4 outputs and execute whatever alarm features are included
according to the parameters present.  If you want to change something, set up the
parameter list on a PC and download it to the unit.  Live with what you've done for
that flight at the very least.  Cockpit unit would scroll and accept a new parameter
list from the PC and that's about all.  Like a GPS that you could page but not change
anything else on the fly.
Just a theory,         Jim S.

That is quite possible. It is probably easier than trying to program the display
processor to allow it to order the list. The RS232 GPS port could be used to download
the list order. Are you willing to boot up your computer in DOS from a floppy
disk? It is much easier to write a download program in DOS rather that windows
as DOS allows direct, almost real time, access to the serial ports while Windows 
does not.

However, since we are unanimous in the desire for a terse list there are only 
about two pages max and most parameters that logical should go together will 
fit on one page only. I for one am not interested in writing a program to allow 
the unit to be programmed from within. Too much work.

I will work on a layout for both pages. Perhaps three if Tracy decides to
go with EGT/CHT and oil and water temps.

Perhaps another idea is have five, six or more pages that can be scrolled through
until you get a grouping you like. That is a very simple user
interface and probably easy to program. Everybody make several that they would
like to see from the list uploaded so far.

BTW I like the idea of a voltage monitor as that is critical to the health of the
EFI hence the engine. If the voltage drops off that is sign of a sick regulator or
alternator and it is time to find a place to land. With the right processor (which
BTW I am waiting for Tracy to choose :-)) that should be a piece of cake.

Tracy, if you choose the one you are using for the EFI there should be a slight
economy of scale advantage needless to say.

BTW Power Sport is way ahead of us on this. They showed a complete firewall forward
package at OSH including a PC sized color LCD that monitored all engine parameters.
Trouble is it was $18,000. I guess we are creeping up on that price :-)
