Reading the catalog entry
The filename Corolla 1.8 2ZRFE 89663-0ZC32.bin identifies the vehicle and engine application alongside the complete calibration number. It does not name a stock or modified variant, or describe a specific software feature.
The calibration identifier is useful when comparing an existing module’s software record with a service document or another catalog entry. Vehicle and module compatibility cannot be established from the filename alone.
