I'm going to be swapping in a 1st gen B16a OBDO into my 91 teggy and was wondering which ecu would be better for this, A PWO or a PR3??? I've heard alot of people say that the PR3 is best for this swap. And on the other hand I heard the same thing about the PWO so if you guys could help on clearing this up I'd appreciate it. I don't want to buy the wrong ecu.
