Controller function and catalog label
An engine control module manages engine operation using sensor inputs and programmed calibrations. Its general responsibilities can include coordinating fuel delivery, ignition and emissions-related operation. The available identifier does not establish which of those functions this particular calibration changes or identify a specific vehicle application.
The STOK label indicates a stock variant. It does not name a modified feature or establish a revision history. The related catalog entry 89663-60K91 identifies the calibration without the file’s stock label.
