What the catalog identifies
The file Tundra 5.7L 3URFE 89663-0CG11.bin supplies the vehicle and engine association. A second entry, 89663-0CG11.bin, carries the same identifier without those details. Neither filename identifies a modified variant or describes a particular change made by this calibration.
