What the engine controller does
The engine control module uses calibration data to manage functions such as fuel injection and ignition timing. It processes sensor information to adjust engine operation as driving conditions change, affecting how the engine starts, idles and responds to the accelerator.
The catalog identifies the engine and calibration number but does not describe a change introduced by this particular revision. It also does not name a modified variant, vehicle model year or market application.
