What the filename identifies
The related catalog identifier is 89663-06601. The suffix TUN_E2 distinguishes this file as a labeled variant of that identifier. The name suggests a tuned version, but it does not establish which calibration settings were changed or what effect those changes have on driving.
The catalog entry does not identify an exact vehicle application or document a specific revision. The engine-control association is therefore a family-level identification, not confirmation of fitment or of the changes in this particular file.
