as above. in the pw0 you dont have the knosk sensor right? what else do these two ecus have different besides the knock sensor and the top speed goverener. most of all which one make more power from factory?

 

if you compare JDM PW0 to PR3 then both have pretty much simliar specs, both equipped with knock sensors boards and have speed limiters. PR3 offers many more programs as far as chipping goes.

(only Euro Pw0 has no knock sensor)

 

i checked in my hondata software and it shows that the pr3 and pw0 both have identical fuel/ignition maps on the hi and low cam profile
