Catalog overview of Toyota Corolla 1.8L 1ZZ-FE firmware 89663-02072 and its engine-control context.
89663-02072.bin is cataloged as firmware for a Toyota Corolla with a 1.8-liter 1ZZ-FE engine. The 89663 part-number family is associated with Toyota engine-control software, so this entry is tentatively identified as an engine control module calibration.
