krousdb did this - calibrated his fuel level sender's voltage - when he was driving his pre-ODBII del Sol, and he actually managed to get decent accuracy from it. To the point that when parking the car back at home at the end of each day, he was able to make decent estimates of his trip MPG (fairly long trip, though).
It's something I'd do if I didn't have access to either a ScanGauge or MPGuino.
