At a recent fillup, the car needed 24% more fuel than expected by the Scangauge. This was odd, as it's generally within 5%. Now all my mileage readings are significantly lower.
...can you readjust the FILLUP value (up or down as necessary) until the "±%" number is *back* to what it was before? Of course, this assumes you wrote-down or recall what that number was before.

I agree. I also think you can leave the SG unconnected for a while and it will reset to defaults.
One thing you might want to check when this happens is if somehow the SG went back to the default values. I"ve had my SG I reset several times that gave me incorrect values.
If you driven it with wrong numbers I think all you can do is just reset it like you filled it up and just ride out the tank until it's time to fill up again. You probably need to confirm the setup values again.
