What the calibration identifies
Engine control calibrations provide operating parameters for functions such as fuel delivery and ignition timing. The complete identifier 89663-42840 distinguishes this catalog entry from other calibrations in the same family. It does not, by itself, establish a specific vehicle application or the changes made to this file.
The MOD_E2 suffix labels this filename as a modified variant. The related catalog entry 89663-42840 supplies the base calibration identifier but does not describe what the E2 modification changes. The label alone is not enough to identify a particular feature or driving effect.
