 Ed,
I used 3mm, but it thinned out a fair bit over a large area. I saw some small parts done and saw not as much thinning. I also used some 4.5mm for some brackets i.e. heat and bend. I wouldn't recommend the thicker stuff for what your doing the 3mm should be more than enough..

Thanks, George
 
I may end up trying that. Sounds like the old vacuum molding technique - generally good for material up to around 1/8" thick as best I recall.

Ed,
I just made some motorbike panniers out of thermoplastic (ABS). I had to make my own moulds (have plenty of experience), took them to the factory- they heat the sheet of plastic drop it on the moulds and suck it down. You have to cut them free from the sheet, but very cheap to make things.

You have a good point. Dave.
 
I wanted to occupy the smallest amount of instrument space consistent with a readable display.  Until the new OLED type display became available, I just was not happy about the quality.  The old one was readable under most lighten and viewing conditions but not all.  This one is much, much better.
 
At the moment, I had planned to package it for the 2 1/4" dia standard instrument hole.  The trouble is I have found no source of reasonably priced instrument cases.  I did find a few metal ones with minor flaws and even those were $25 apiece on sale.
 
I know somebody much make them - plastic would undoubtedly be cheaper.  But, the instrument can be mounted in a black plastic box as far as that goes.
 
I scratch my head a bit more over this issue.

You know, Ed, Maybe you should not worry about the packaging so much.  You could leave that up to the builder as most of us are going to be installing it in our own unique way.  It could be mounted right onto the instrument panel, or given a simple case made of aluminum or fiberglass.

Last photos - MVC-018F shows the EC2 fuel map that is currently loaded in my aircraft.  There are now two segments a <3000rpm and >3000 rpm represented here by the red and blue graphs respectively. 
 
The screen shows where you have manually placed a cursor (white bar) and gives the Map reading at that location (white) as well as the value to the left(red) and right(blue) digits.  There is a little green circle (hard to see in the photo but not in real life) that represents the fuel map area the engine is operating at the moment.
 
And you can select an expanded scale screen to show either the low (red) Map or high (blue) map, the latter of which is shown here.
 
There are a number of other screens mainly for calibration that are not show.  You can calibrate the gadget to reflect your own injection system, change it for larger/different injectors as well as adjust the O2 sensor display sensitive.
 
So See Dave, I have been busy working of the gadget of your interest{:>)  Now, working hard to have one for Sun and Fun.  The electronic/programming/board making part - I like.  Its the packaging that drives me batty - should be so simple but turns out  in some ways to be the hardest part.
