I know you can get a license plate bracket with LED's on it. It's designed to type in a scrolling message via an RS232 cable. It should be possible to plug in the cable to the onboard computer and have it throw just the right data to the LED's.Holicow said:How about a display for the instantaneous mpg, in numerals? Do you think this is possible? I would love one of those. Sorry to veer off topic
I have neither the time nor the knowhow to do this though.
