Hi,
The calibration parameters include cross-axis sensitivity for xy, xz, yx, yz, zx and zy. This means that when z axis is tilted, the final calibrated acceleration values of X, Y and Z axes should be still accurate for you to get the precise tilt angle values, where X/Y/Z axes are device body axes, not the BMA456 x/y/z axes.
If possible, please provide detailed examples and data for this issue including calibration parameters, BMA456 raw data and final calibrated values.
Thanks.
