What the identifier describes
The related catalog entry 89663-02G32 supplies the base calibration identifier. The filename adds -TUN, a label commonly used for a tuned or modified variant. It does not identify which settings were changed or establish a particular performance effect.
In normal operation, an engine control module uses its calibration to interpret operating conditions and command engine functions. A modified calibration can change that behavior, but the filename does not show whether this variant alters fuel, ignition, torque limits or another setting.
The complete identifier is important when comparing calibration records. A similar-looking 89663 number does not, by itself, establish that another file has the same application or software content.
