The calibration on the SGII is pretty simple. When you fill up, you tell it how many actual gallons were used* and it recalibrates based on actual gallons used.

*(don't alter this the first time you fill up with it, but do let it know you filled up. Otherwise, it will assume you used all the gallons you put in since you installed it and will give you very inaccurate results. If you installed it half way through a 20 gallon tank, then fill it up after you've used another five gallons, it'll assume you used 15 gallons to travel however many miles you did since installing it)
