Controller Pitch rotation offset

[Hawat3000]

Hello, I am trying to make a 90º pitch rotation for the VIve controller.
The yaw and roll angles are ok but you have to overthrow the controller to aim
I have seen that there is a "rotation_offset" in the profile json file with w, x, y and z values but I dont understand how it works (are they quaternion?) I have test different values in every angle with not luck.
Also I have try to adjust with the gui but I cant see the model
Can someone guide me how these values works?
Regards
