A method is provided for determining whether an injection parameter correction for fuel quality is required in an internal combustion engine, the engine comprising a plurality of cylinders, each one of the cylinders comprising a combustion chamber into which fuel is injected by an associated fuel injector and within which, in use, combustion events repeatedly occur to define a combustion cycle of the cylinder between successive combustion events. The method comprises observing the speed of the combustion cycles of at least two of the cylinders and analysing the at least two speeds to determine if an injection parameter correction for fuel quality is required. The invention also extends to an injector control unit arranged to determine an injection parameter correction for fuel quality.
