PW0 or PR3

[4doorb16]

I know alot of people say PR3 is better but why?

ive herd that before also. people was saying that pr3 redlines at 8200 but the pw0 redilines at 8000 and pr3 gives more fuel ive herd but the only thing that ive experiencedis pr3 mostly come automatic i have a 91 jdm b16 integra with a pwo manual pwo ecu it moves. but when i pluged in a pr3 ecu the vtec kicked in at 4400 and redlined at 7400 i found out that it was a automatic ecu i tried like 10 pr3 ecus in my car and they were automatic if you have to choose open both ecus and look at the vtec circuit board it should say AT or MT i think you can figure that out

pr3 and pw0 both give the same amount of fuel, and the ignition tables are identical.

one checks for two O2 sensors i believe whereas the other checks for one.. i forget which is which, but do a search.. i belive a few months ago i answered this
