What the calibration controls
The engine control module regulates functions such as fuel injection, ignition timing and electronic throttle operation. These controls affect how the engine starts, idles and responds to the accelerator. The calibration provides the settings the module uses for those decisions.
The catalog entry identifies the calibration as 89663-02662.bin, but does not name a stock or modified variant or describe a change introduced by this revision. The identifier alone does not establish compatibility with every Corolla fitted with a 2ZR-FE engine.
