Each injector in the plurality of injectors includes a respective hydromechanical scheduling valve member configured to regulate fuel flow from a respective inlet to a respective nozzle of each injector of the plurality of injectors as a function of pressure input from the manifold to the respective main circuits. A valve block is connected in fluid communication with a respective auxiliary circuit in each injector in the plurality of injectors. The auxiliary circuit is operatively connected to adjust position of the respective scheduling valve member for actuating force modification of the scheduling valve member. The valve block is configured to control all of the injectors in the plurality of injectors as a block.
