What the filename identifies
The related catalog identifier is 89663-02G32. In the longer filename, TUN_E2_V2 distinguishes this file as a labeled variant. TUN suggests a tuning-oriented file, while V2 suggests a version designation. The catalog does not explain E2 or specify which engine-control settings differ from a stock calibration.
A calibration identifier helps distinguish software records, but it is not by itself a vehicle fitment listing. The filename does not confirm a particular Toyota or Lexus model, production year, controller hardware, or driving improvement.
