What the stock label means
The STOK suffix indicates a stock, or unmodified, variant in the catalog filename. It is a variant label rather than part of the calibration identifier. The related catalog entry is listed as 89663-60G02.
Engine control software generally processes sensor information to manage functions such as fuel delivery and ignition timing. That describes the controller family’s role, not a confirmed feature or revision change specific to 89663-60G02.
