Controller role and identification

An engine control module uses sensor inputs to manage functions such as fuel delivery and ignition timing. Those general responsibilities do not establish which functions this particular file changes or which vehicle it fits.

The complete filename includes the _E2 suffix. The catalog entry does not explain whether that suffix identifies a calibration variant, file segment, or another distinction. No stock or modified behavior is identified by the supplied names.
