Can anyone with inside information tell me the formula that the Scangauge uses to determine mpg or how the calibration can pass through a maximum?

But my Scanguage calibration bumps all over the place when I refill, from about 17% to the high 20s, so I'll be interested in the othe replies.

I followed the instructions about topping the fuel off and adjusted the Unit accordingly.

Comparing the Unit's MPGallon and my own calculation with a calculator the first 3 tanks were out 20%,20% and 17%.

I recalibrated the SPEED function by 1 increment and now my in dash trip meter coincides with the MILEAGE ON TANK by 1%.

The last 4 tanks have a deviation of +/- 2%

Not to brag but I am getting over 21MPG in the city! (11.1L/100km) LOL
