Abstract: A method of bank to bank trimming for a locomotive engine during steady state operation comprises receiving a plurality of operating parameter signals, receiving a fuel quantity signal for each of a standard cylinder bank and a donor cylinder bank, providing a trim map, determining whether the engine is operating in a steady state condition based on the plurality of operating parameter signals, determining a target fuel injection duration for each of the standard cylinder bank and the donor cylinder bank if the engine is operating in a steady state condition, and adjusting an actual fuel injection duration to equal the target fuel injection duration for the standard cylinder bank and the donor cylinder bank.
