Calibration and variant identifiers
An engine control computer uses sensor inputs to manage functions such as fuel delivery and ignition timing. The catalog identifier alone does not establish which of those functions this particular file changes, or which vehicle it applies to.
The suffix TUN_E2_V2 is a filename variant label. Its exact meaning is not established by the related catalog entry, so it should not be treated as evidence of a specific tuning change or feature. The related identifier 89663-33A72 does not carry that suffix.
