Catalog files and variant labels
The filename Venza 2.7L 1ARFE 89663-0T220.bin identifies the vehicle and engine associated with this entry. The catalog also lists 89663-0T220.bin without a modification label, alongside two files labeled 89663-0T220-_MOD.bin and 89663-0T220-_MOD_E2.bin.
MOD indicates a modified variant, while E2 is an additional label found only on the MOD_E2 file. The filenames do not establish what either modification changes or confirm that the unmarked file is an original factory calibration.
The Venza and 1AR-FE identification helps distinguish this calibration from other Toyota firmware with similar part-number prefixes. The catalog entry alone does not establish an exact model year or vehicle-specific compatibility.
