Trying to find the best and most useful obd gauge that will help me drive better. I know both of these are around the same price range, but it seems like ultra gauge has been around longer. The thing I like about the ecometer is that it has color to indicate when you are driving above the "avg" mpg. How accurate are these two? and Do you really look at these gauges often when you drive?
