Catalog variants
The entry appears as 89663-35233_TUN_E2.bin, 89663-35233_TUN.bin and 89663-35233_E2.bin. A separate file is named 89663-35233- (2).bin. The two TUN-named variants also appear as .rar archives.

The complete calibration identifier is useful when distinguishing this entry from other Toyota engine-control records. A matching part-number family alone does not establish that a file is suitable for a particular vehicle or controller.
