A system is provided for monitoring and testing engine emissions during normal operations. The system monitors and logs engine data to determine when the engine is operating at a steady-state within a defined test mode. The system may measure and log multiple sets of emissions data while the engine is operating in the defined test mode. The multiple sets of emissions data may be aggregated for qualifying the engine and may provide trend information about the engine. The test mode definition may be revised based on the logged engine data. The system may be used to selectively monitor one or more of a set of multiple engines.
