NOOB: My Scangauge is way off suddenly.

So when I first plugged it in, I set the engine size, fuel tank size, and wheel size compensation (3%). I finished the 3/4 tank I had in the car with approx 42mpg on the avg... which sounded great.

Sure enough my mileage for that full tank was 38mpg, so I was sure the gauge would be closer now. I filled it up from E till the pump stopped automatically. It was at 10.008 gallons out of my maximum of 12. I hit the REFILL button, and I cant remember if I hit save or not.

Ever since then, I'm getting readings that show an average of 20mpg at the best, though the dashboard gauge is consistent with my 38mpg tanks progress.

So I've used about 1/8 tank... how do I get it back in the neighborhood of realistic mpg calculations?
