IIRC it is the version of the ECU available in the other parts of the world that run the VTEC-E such as the D15Z7 in Europe. But this is going off of memory from one other user (that I can't find the PM from) that had an N01 P07 ECU. I do remember that he was not located in the U.S. though.
Correction:
Honda ECU label Decode
N01 usually denotes a factory reprogram, no particular market.
So it should work just fine.
