			'''Note:''' Ensure it is rotated in clean 90-degree increments relative to the vehicle’s primary axes. Avoid mounting the device at an arbitrary angle, as this can affect sensor accuracy.

Hold the device in free air at the '''new orientation''', then swap or invert IMU channels using the RaceCapture app to match the behavior seen with the default orientation and default channel mappings.

	~~==Zero Calibration==~~
	After orientation is updated (as needed) and the system is mounted to the vehicle, ensure the vehicle is on a level surface. Then, perform a final zero calibration by pressing the Calibrate button in the RaceCapture app. This will zero out all 6 axis. At this point you can perform a final write / save of your configuration

			==Smoothing==
			The Accel/Gyro configuration screen includes a '''Smoothing''' slider that controls the amount of filtering applied to the IMU output.

			* '''Less''' (slider to the left): Minimal filtering, producing raw and highly responsive data. This is useful for capturing sharp, short-duration events such as curb strikes or sudden inputs, but may introduce more noise into the signal.
			* '''More''' (slider to the right): Increased filtering, producing a smoother signal by averaging out rapid fluctuations. This is better suited for general handling analysis where a cleaner trace is preferred.

			Adjust the smoothing level to suit your logging and analysis goals. For most track driving applications, a moderate smoothing setting is a good starting point.

			Systems with an on-board IMU should be mounted in the default orientation, typically with the device connectors oriented towards the front of the vehicle.

			==Mounting in an alternate orientation==
			The system can be mounted in an alternate orientation, ideally in square 90 degree increments. For example:
			* Inverted mounting
			* Flat / upright, but rotated 90 degrees
			* On-edge, but aligned with the front-rear axis of the vehicle
