Engine-control calibration
An ECM manages engine operation using sensor inputs and calibration data. Depending on the vehicle, its software can control functions such as fuel delivery, ignition timing and emissions-related operation. The catalog identifier alone does not establish which of those functions this particular calibration changes or the vehicle application.
The filename labels this file MOD_E2, indicating a modified variant. It does not define what the modification does. The related catalog entry 89663-33E90 identifies the calibration without naming a stock or modified variant.
