I used to see ads for a programmable module of about 6-7 LEDs that you could set up to show shift point, yellow warning, red line, etc. The same company made a gear indicator; both were usually in the same ad. I think maybe Aerostitch carried them, also saw them in magazine ads. Can't seem to find them now, and am wondering if it can be adapted to my 4 cyl Miata. Anyone know who carries these? Thanks for any leads - TT
