The ScanGauge worked for me. With it I can see instantaneously the effects on fuel consumption due to speed, wind, rain, road grade, etc . Such information encourages me to adjust throttle settings for maximum fuel economy under any given circumstance.
One great feature of the ScanGauge is that by pressing buttons on the face of the gauge you can change and see whatever instrument reading you want. It is a lot easier to use than many others out there.
