What the filename identifies
The complete identifier combines the vehicle and engine description with Denso, calibration number 89663-60551, and the variant label TUN E2 V2. The related catalog entry 89663-60551 shares the calibration number but does not name that variant.
TUN suggests a tuned variant, while V2 denotes a version label. The filename does not establish what was changed, and E2 cannot be assigned a specific function from the identifier alone. The engine-control functions described above are the controller family's general role, not confirmed changes in this particular file.
The catalog name identifies a Land Cruiser 4.0 application, but it does not establish a model year, market or exact vehicle compatibility.
