What the identifier tells you
As an engine-control calibration, the software may contain settings used for functions such as fuel delivery, ignition timing and emissions control. The identifier alone does not establish which of those functions this particular revision changes, or which vehicle and engine it belongs to.
The complete code 89663-60Y30 should be checked against the vehicle’s electronic control module and applicable service documentation when identifying a calibration. A similar-looking number is not enough to establish that two calibrations have the same application.
