Engine ECU function
The engine ECU uses sensor readings to manage engine operation. Depending on the vehicle and engine, its software controls functions such as fuel injection, ignition timing, idle speed and emissions-related operation. The calibration supplies the settings and control data used by the ECU for its intended application.
No stock or modified variant label is present in the filename. The identifier should therefore be treated as a calibration reference rather than evidence of a particular performance feature or software update.
