What the engine controller does

The engine control module uses sensor information to manage functions such as fuel injection and ignition timing. These controls affect how the engine starts, runs and responds to the accelerator. The exact behavior or changes introduced by calibration 89663-28354 are not identified in the catalog filenames.

Catalog identification

The file Estima 2.4 2AZFE 89663-28354.bin identifies the vehicle, engine and calibration together. A second entry, 89663-28354.bin, carries the same identifier without a vehicle or variant label. Neither filename identifies a stock or modified variant, so no particular tuning change can be attributed to either file.
