Identification & application notes

Honda official archive says EF3 Si family was announced September 1987 and ended August 1991; that is vehicle-family context, not proof this ECU revision covers every year.
CR-X/Integra from original title are not established as exact applications. A broad CR-X diagram lists multiple ECU revisions and cannot prove individual engine/transmission interchange.
Request a clear factory-code photo and donor year/chassis before describing this particular physical unit as verified PM7-000.
Expanded exact-code review did not establish a defensible broader application than the existing EF3 Si Extra ZC manual catalogue example.
No new physical label evidence identifies this offered ECU as PM7-000. The number shown is an application reference. Contact us to confirm the full factory label, donor details and programming requirements before ordering.
