A fuel injection pump unit consists of a fuel injection pump (1), in which a quantity-determining member (6) is set by an actuator (13), its position being detected by a position sensor (15), and of a control unit (2) which calculates an injection quantity (M) and from that, using a stored ignition characteristic (33), determines a set value ( beta set) for the quantity-determining member (6). To provide a simple and precise calibration of the pump unit with minimal complexity, there are two adjustable stop faces (21, 22) which delimit the travel of the quantity-determining member (6) and in each case define a position of the quantity-determining member ( beta 1, beta 2) commensurate with a certain measured injection quantity (M1, M2), in each case at a certain distance (k1, k2) from their opposite surfaces (23, 24), at least one of them being selected so that contact is not made with the opposite surface (23, 24) unless the quantity-determining member reaches points outside its dynamic adjustment range for injection quantity.
