Engine-control role and file variant
An engine control module uses its calibration to govern functions such as fuel delivery, ignition timing and emissions-related operation. These settings affect how the engine responds and runs. The particular behavior changed by this file cannot be established from its name.
The MOD_E2 suffix identifies this file as a modified variant. The related catalog entry 89663-60710 provides the underlying calibration identifier but does not describe the modification or identify a stock file. The filename does not establish what E2 changes, so it should not be treated as evidence of a specific feature or performance outcome.
