What the filename identifies
The base number 89663-05461 identifies the calibration record. The suffix TUN_EVRO2 is a variant label on this particular file. It suggests a tuned version described as Euro 2, but the filename alone does not establish which emissions functions have been changed or how the file affects vehicle operation.
The catalog entry does not identify a vehicle model, engine or exact controller application. The engine-control association describes the part-number family rather than a verified change made by this revision.
