What the identifier tells you
The catalog names do not establish which control module uses this calibration or what vehicle function the software controls. They also do not identify a vehicle application or describe a stock or modified variant. The full identifier, including its suffix, is therefore the most useful way to distinguish this record when comparing it with a vehicle’s calibration information.
