Between RefValk and myself we could come up with something. But, it would not be cheap. The original LCD display appears to be special and not a computer screen. The easiest way to add integrated electronics would be to scrap the original LCD display and replace it with a palm pilot type screen. Then, run software to coordinate what is being shown, doing the calculations for fuel economy etc.
You are looking at $2,000+ to design and build a low rate production.
I think that for now I will continue investigating eloptic energy sensors rather than 'strument up my Rune. :shock:
