What the catalog filename identifies
The file LC200 5.7 3URFE 89663-60C55.bin identifies the Land Cruiser 200 series, its 5.7-liter 3UR-FE engine and the complete calibration identifier. The .bin extension denotes a binary firmware file. The filename does not name a stock or modified variant.
The identifier ties this entry to an engine-control calibration, but it does not by itself establish what changed in this particular revision. When comparing service records or module data, the complete calibration number is more useful than a partial prefix because similar numbers can refer to different software records.
