A selection module selects a gear ratio for a transmission, a turbine speed for a torque converter, and a torque request for an engine. A fueling determination module determines a first fueling rate based on a first cylinder firing fraction, the torque request, and an engine speed and determines a second fueling rate based on a second cylinder firing fraction, the torque request, and the engine speed. A mapping module selects one of the first and second cylinder firing fractions based on a comparison of the first and second fueling rates and stores the selected one of the first and second cylinder firing fractions in an entry of a mapping corresponding to the gear ratio, the turbine speed, and the torque request.
