I have never run into a J4 ecu. If i had to guess, I would guess that is the 180sx type X 1997-1998 Blacktop SR20DET Automatic ECU
I would try to contact your vendor to try and swap ECU's. They also may be more knowledgeable than I. Quickest way to find out is to swap ecus with a friend if that is available to you.
