What's the differences between these three JDM ecus?

I heard that the PR3-J01, are hard to come by. My friend has one, but he said it's OBD-1... I thought the PR3's were all OBD-0? If it is OBD-0, is it worth getting? Will it be any improvement over my PW0 (7500 revlimit)?

Thanks in advance.

 

I have a PWO and the rev limit is not 7500 it is the same as the pr3 8200. From what I have read the PWO and the PR3 are pretty much the same ECU. I think the PR3 just has a higher speed. The PWO is governed at 117mph. anyone correct me if I am wrong.

Auto PR3 ECU's. And your tach was off... My PW0 is like ~8000 rev limited.
