Have 4500/3500 combination. Calibrated my fuel tanks on the 3500EE a few months ago. All good...digital quantity reading is right and the graphical bars looked right.

Then just last week (I think after updateing the 4500 s/w to .22) the graphical depiction on the 3500 has a left bar that is gone. The set up menu for tank 1shows a capacity of like 47000000 gallons and it should be 52. The right tank is fine, and the bars on the 4500 screen for both tanks are fine. I can not adjust the erroneous quantity out. Tried restoring the tanks.afd file from 1/28/12 and that is NOGO as well.

Any ideas?

Thanks.

Gordon
