Mini R56 Installing Eccentric Shaft Motor

[Buggy]

Hi,
I am in the process of rebuilding the head on a 2007 R56 N12B14 and not sure how to reinstall the eccentric shaft motor. Based on the online TIS manual I need to wind the motor in but there are no details of the position the toothed cam on the shaft needs to be in when reinstalling the motor.
Can anyone help please ?
Many thanks,
Mark

Thanks Elliot.
Does the software and cable sold on eBay allow me to do the calibration?
