Calibration and variant label
The catalog entry 89663-30E20 identifies the calibration family represented by the filename. The suffix A_MOD_E2 distinguishes this file as a modified variant. It does not, by itself, establish what was changed or how the vehicle would behave differently from stock.
Engine control software generally manages functions such as fuel delivery, ignition timing and emissions-related operation using sensor inputs. That family-level role should not be taken as confirmation of a particular modification or feature in this file.
