United States Domestic Market - cars destined/made for the United States. Compare to: EDM, JDMNote: USDM OBD1 Civic Integra ECUs generally are the most feature-filled ECUs, and generally have the Injector Test Circuit, Knock Sensor (in DOHC VTEC ECUs), Electrical Load Detector and Pressure Atmosphere sensors. They generally do not have surface mount components, and use a larger rectangular case compared to JDM ECUs. They also generally do not have a Speed Limiter.
