dcb, is there another analog input available on the MPGuino and enough space for some code to monitor the MAP voltage and display a live bargraph display of the engine vacuum? It might be asking too much, but I'd love to see a slightly smaller font on the MPGuino "big" displays, and a bargraph underneath showing a live vacuum reading. I hate the big ugly mechanical vacuum gauge in my Metro, but love having that additional piece of info while I'm driving.
I suppose I could do something with the appropriate parts and 10-20 LEDs, but it would be so clean to have it all on the one display.
