When trying to do a magnetic calibration, I always get an error data points not being elliptical.

I had a similar problem - turned out that it was caused by the rebar in the ramp. I now do my calibration on an asphalt ramp.
Hope this helps,

Maybe I was too close to the hangars. There's a giant asphalt ramp that is completely empty, I'll take it out there and try it again. Thanks!
