As the vintage freak I am, I was first thinking about a row of small nixie-tubes but they are bulkier, trickier to drive and about one decade older than the car. 7-segment VFD´s may be a more suitable alternative to the red LED´s. I have a bunch of high-res. bar-graph VFD´s somewhere too and a desktop calculator with unusual 8- or 9-segment VFD digits. Nixies would be perfectly right for my 1964 two-stroke Saab 96 when it´s finaly ready. To my 1959 Heinkel three-wheeler a row of dekatron tubes would be just right. :-)
My idea to have a separate display unit for my FEC makes it easy to choose and change between any display types I want. I´ll start with the 7-segment LED´s.
It´s funny how easy it is to get carried away by visual gimmics instead of the way more important problem with how to select and present all data...
