Engine control and the 1UR-FSE
The engine control module uses sensor inputs to coordinate functions such as fuel injection, ignition timing and electronic throttle operation. On the 1UR-FSE, it also manages the engine’s combined direct and port fuel injection system. These controls affect starting, drivability, fuel consumption and emissions.
The identifier 89663-50G52 distinguishes this catalog record from other engine calibrations. The catalog does not identify a particular revision change or a modified variant, so the general functions of the engine controller should not be read as a list of changes made by this specific file.
