i had a quick question. wat is the difference between the PR3 ecu and the PW0? i kno one came out of the CRX/Civic SiR and the other came out of the Integra XSi but which came from which car and wat are the spec differences because they both had B16A's in them, right?

 

pr3=EF9
pwo=XSI

they have slightly differet maps. ive used both on the same car and i didnt notice anything different.

Other way around..

PW0 = ef8/ef9 and edm vtec's
PR3 = 90-93 j-spec integra ,92-93 are obd1 of course.

Dont know if the maps are different i never looked at them but either one will run a b16a fine.

 

Almost the same, it will certainly run that way.
The PR3 for some reason is easier to reprogram, and more custom maps are availble for it.

 

koo i just eneded up buyin one on ebay for $51.00 just hope the guy doesnt flake on me. i have a PW0 but my friend tried it out on his car and said it acted a lil funny so i got the PR3 just in case. not too bad for the price dont u guys think
