Gas gauge not working? I think I fixed it.

I can make a circuit with a 50 cent micro-controller and a few other components that will enable calibration of the empty and full. It works by separating the sender measurement, from driving the gauge. There will be a special calibration procedure performed at empty and full. It will correct for off specification senders and gauges, if they function in a monotonic manner.

If more than a few have interest, I will start a separate thread, develop the schematic, parts list and simple software for the system. I do not have interest in selling units, but I can see helping someone get setup up.
