I've messed with the VR tracking enough, and never could quite get it perfect, or even close. Yaw drifts with pitch, since the earth's magnetic north is actually at an angle down from you, not just around.
However, I was trying to create a glovepie script to accomodate this, but I just happened to stumble upon this gem. Not sure if it will work for everyone, but here goes:

1.Open the calibrator, hold VR920 in air in front of you.

2.Spin Vr920 ALL the way around all three axis, several times, slowly. It needs calibration for acceleration as well, which will get mussed up with sharp movements.

3.Hit Lock Calibration. DO NOT ZERO OUT.

4. Place the VR920 flat on a surface that is not magnetic or even near something magnetic. A clear wooden table works, or even just clearing a big spot off a desk.

5.Making sure it's flat, Align it with exactly 179° or -179°. Being flat, it will also line up exactly with yaw and pitch.

6.Zero it out carefully.

The VR920 default yaw is exactly opposite magnetic north. For some reason, forcing it to zero the other direction causes it to be able to accommodate much better.

Try this yourself, then post on here if it works. I haven't been able to test anywhere else than where I am, so I need the input.
