What the identifiers mean
The related catalog entry 89663-52F11 identifies the underlying calibration. The filename adds MOD_E2, indicating a modified variant. That label does not, by itself, establish which engine-control functions were changed or how the vehicle would behave differently from stock.

Those are controller-family functions, not confirmed changes made by this particular file. The catalog name does not identify a specific Toyota or Lexus model, engine or compatible control module.
