Abstract
A method for generating a camshaft signature for camshaft positioning calibration for a camshaft included in a combustion engine. The camshaft is adapted to cause a valve to open and close an opening to a cylinder volume of the combustion engine. The combustion engine further includes an intake surge tank adapted for receiving air from the outside environment. The intake surge tank is in fluid connection with the cylinder volume of the combustion engine for providing air for mixing with fuel injected into the cylinder.
