What the calibration family controls
An engine control module uses calibration data to manage functions such as fuel delivery, ignition timing and emissions control. Those settings affect how the engine starts, responds to the accelerator and operates under changing driving conditions. The identifier alone does not establish which of those settings this particular calibration contains or changes.
The related catalog entry is listed as 89663-22220. The filename suffix (2) distinguishes this file name, but it does not identify a stock tune, a modified feature or a software revision. No specific vehicle application or compatibility can be established from the identifier alone.
