System and method for controlling the air flow of an internal combustion engine

There are provided for operating an internal combustion engine during conditions where the ambient humidity changes over time, methods and systems. In one non-limiting example, an engine air flow rate limit value is set to increase the engine air throughput during conditions of high humidity, so that an internal combustion engine during high humidity conditions as compared to when the internal combustion engine is operated during conditions of low humidity, an equivalent can deliver torque.
