What the identifier tells us
The complete calibration identifier is 89663-60N41. The related catalog name matches that identifier but does not specify a vehicle, engine, controller variant or stock or modified label. It therefore does not establish which engine functions this particular revision changes.
The calibration number is useful when comparing a vehicle’s recorded software identification with a catalog entry. A similar-looking number alone is not enough to establish that two calibrations have the same application or behavior.
