I emailed a screen shot of both left and right AD values as per Shawn's request to info@advanced-flight-systems.com. I calibrated the left tank as per this forum thread above http://www.advanced-flight-systems.c...nk-calibration using 5 calibration points. Not sure if I "zeroed" both ground and flight values first to get this number spread.

Today I did a calibration for the right wing using 11 calibration points and "zeroed" only the ground values first. As you can see (with difficulty) the AD numbers are all the same again.

I guess this problem is not solved after all.
