Zusammenfassung:	A method of acquiring population data from engine control modules provided with a memory for storing data relating to parameters of engine operation. The method includes the steps of downloading stored data from a plurality of engine control modules when the engine control modules are reprogrammed. A set of population data is developed and communicated to a central database (112). The population data is statistically analyzed (114) when a statistically significant portion of the population is obtained. The statistical analysis of the population data is then used to make engine design modifications (116), provide warranty problem analysis (118), and analysis of optional feature acceptance (120).
