Understanding the file label
The filename adds TUN_E2 to the calibration identifier. It distinguishes this file from the related catalog entry 89663-42B82, but the available label does not identify a specific modification or confirm what the suffix means in operation.
No vehicle model, service bulletin or documented change is associated with this entry. The identifier alone therefore does not establish which engine settings differ from another calibration or whether the file is suitable for a particular vehicle.
