What the filename identifies
The base identifier 89663-33A52 connects the file to the related calibration entry. The added TUN_E2_V2 label distinguishes this file as a named variant. TUN suggests a tuned version, while E2 and V2 are variant labels whose precise meanings are not established by the filename alone. They do not by themselves document a particular performance or emissions change.
