Engine control software and the MOD label
An engine control module uses its software and calibration data to manage engine operation. Depending on the vehicle, these controls can include fuel delivery, ignition timing, emissions functions and responses to sensor inputs. Those are general functions of the controller family, not confirmed changes made by this file.
The _MOD suffix identifies this filename as a modified variant. The related catalog entry 89663-60J90 provides the base identifier, but it does not describe what was modified or establish a stock-versus-modified feature list.
