I've been thinking it would be awesome for some time to have a tach on the transmission and one on the motor to make it easy to tach match. I was further thinking that it would be totally awesome to have two needles on the same gauge so that you simply lined up the two needles and then viola (sp) it is simple and uber (two dots over u ) cool to rev match easily. Has anyone heard of a gauge like this? Or of anyone doing it/ have any ideas on how? It would probably also work to mount a second tach next to the main one with about the same scale and then rev matching would be easier. I can rev match without it, but I think it would look awesome, be very practical, and very informative while making rev matching insanely simple. Any opinions or ideas would be great
