Non-Camera relative movement with the OVRPlayerController

So it looks like its coming from this code.   But maybe I'm just looking in the wrong place.   I want the movement to always go in the same direction regardless of head orientation.  Any ideas would go a long way.   Thank you.

OVRPlayerController.cs

            if (primaryAxis.y > 0.0f)

                MoveThrottle += ort * (primaryAxis.y * transform.lossyScale.z * moveInfluence * Vector3.forward);

            if (primaryAxis.y < 0.0f)

                MoveThrottle += ort * (Mathf.Abs(primaryAxis.y) * transform.lossyScale.z * moveInfluence *

                                       BackAndSideDampen * Vector3.back);

            if (primaryAxis.x < 0.0f)

                MoveThrottle += ort * (Mathf.Abs(primaryAxis.x) * transform.lossyScale.x * moveInfluence *

                                       BackAndSideDampen * Vector3.left);

            if (primaryAxis.x > 0.0f)

                MoveThrottle += ort * (primaryAxis.x * transform.lossyScale.x * moveInfluence * BackAndSideDampen *

moveDirection += MoveThrottle * SimulationRate * Time.deltaTime;
