Calibration and variant label

The related catalog entry 89663-33702 supplies the base calibration identifier. The suffix TUN_E2 distinguishes this filename from that base entry and suggests a tuned variant, but it does not describe a specific change to engine behavior. It is not enough to establish whether the file alters power delivery, emissions-related operation, or another control strategy.

The base catalog name also does not by itself confirm that the corresponding file is stock. Identifying the precise application or comparing the variants would require additional information about the controller and calibration contents.
