but how functional would this be in day to day operation (I have 0 experience with these gauges)<ul><li><a href="http://www.impconcepts.com/airfuelmeterforsale.htm">http://www.impconcepts.com/airfuelmeterforsale.htm</a</li></ul>

At part throttle it should look like Kitt from Knight Rider.

Default They are usually all the same anyway if they are 10 LED, since that is the off the shelf LED driver

chip available from any electronic parts store. The voltage input is usually calibrated to read in increments of 0.1V (from 0.1 to 1.0V) which corresponds to A/F's from ~ 17:1 to 12.5:1

If you want to fancy it up, you can get white letter transfer and etch from left to right

17:1 16:1 15.5:1 15:1 14.7:1 14.6:1 14.5:1 14.2:1 13.2:1 12.5:1

Assuming your gauge really is set at 0.1V increments.

Default I think the bad thing about the autometer gauge is it acts like a disco ball

since it only lights up 1 single led at a time, where most of the other gauges light up all of the lights as it goes up.

Default My gauge is one light too. Looks like Knight rider as Mike O said :) I forgot who made it...

but it's a one of a kind sold by racerparts.com or something with a built in Fuel Injector duty cycle , so two knight rider lights dancing around each other

Default LOL I like that boost gauge. Been thinking of a way to add one without destroying the look

I tried from the flip up lower tray where the fuel button is at, but it's too low and ugly.
