What the file identifies
The related catalog entry, 89663-47120, establishes the base calibration identifier. The longer filename adds A-TUN_E2 as a variant label. The available catalog information does not define that label or establish what changes this file makes to the base calibration.
The identifier alone does not establish a specific vehicle application or a particular emissions, performance, or drivability change. Those details require a matching vehicle and ECU calibration record.
