Yuck. I agree, that is soooo 80's. Looks like it belongs in a crappy Oldsmobile.
BTW, stock analog guages would be much easier to read on the road or track. Your eye reads the motion of the tach better with a sweeping arm. The sequential lights on the digital tach would simulate that effect, but to a lesser extent because they only draw the outline of an arc - there is no arm. Add to that,the digital lights stay on so your eye is looking for the leading edge of light. That's much harder to discern that an arm on an analog board.

. How do the gauges get their readings?
