ScanGauge E mileage calculation.
While filling up today I noted all the "Tank" readings on the ScanGauge E and was surprised to see it had calculated the mileage driven 2.5% less than the vehicle odometer. As a result it had calculated poorer mpg value than actual.
There doesn't seem to be any calibration for the mileage.
Has anyone else experienced this and did you figure out a work-a-round?
Or, like me, did you just shrug and say, "it's all relative anyway".
