ABSTRACT:
A method of generating a metric data set for determining a performance of a catalytic converter includes sampling data from a post catalytic converter oxygen sensor to provide a raw data set and generating a revised data set based on the raw data set. Data within the revised data set is eliminated based on characteristics of data points of the revised data set and the revised data set is filtered to provide the metric data set.
