A method of controlling fuel injection in an internal combustion engine having at least one cylinder with an associated electrically actuated fuel injector for performing injection events, wherein a drive signal is applied to the fuel injector in order to actuate a needle therein that controls flow through a valve seat. The drive signal comprises a fueling pulse adapted to move and/or hold the needle to an open position relative to a valve seat, followed by a braking pulse adapted to slow down the needle moving towards a closed position relative to the valve seat, the braking pulse being separated from the fueling pulse by a separation period. The braking pulse is configured to end at a timing that substantially matches the moment when the needle reaches the closed position.
