I'm rather confused about what you are saying.
The stepper motor is a part within the metering oil-pump itself, not in the ECU. The pressure sensor is a part separate from the ECU as well, and is located on the passenger strut tower. There is an atmospheric pressure sensor located within the ECU -- but that rarely if ever is an issue. If your OMP killed the ECU, it likely killed the circuits that drive the stepper motor. You can either try to repair those defective parts, chip the ECU to eliminate "limp" mode, or replace the ECU/OMP.

N370 ecu's are indeed hard to find. There are two pressure sensors for the car, a map sensor for the engine bolted to the pass. side strut tower and one in the ecu for barometric. If your only threw a code for the MAP sensor start investigating there first. What all codes did it throw? Usually a car with a failed MOP will drive ok for a few minutes before going into limp mode.

Some get codes and some doesn't

You can always use an N374. The N374 has a top-speed fuel cut that gets falsely triggered on the N370 harness, so you have to remove a pin to prevent that from happening. Can't recall which at the moment, but it's not difficult to figure out.
