Engine-control context
The engine control module manages engine operation using sensor inputs and programmed calibration data. Depending on the engine and vehicle configuration, its software can control functions such as fuel delivery and ignition timing or fuel injection timing.
The complete identifier distinguishes this calibration from other Toyota software records. The catalog entry does not establish the engine, model year, market or a specific change made by 89663-60X26. It also does not name a modified variant or describe a revision to a particular driving behavior.
