Anyone knows? Thx.

 

anyone please

 

There could be a book on this subject. You should tell what you know to save other's time telling not needed info.

 

well- to start off- the PR3 ECU was in the JDM EF8 CR-X SiR and the EF9 Civic SiR. Only came in manual trans. The PW0 ECU was out of the JDM DA6/8 Integra XSi/RSi. It came in auto or manual trans. The PR3 has a revlimiter/fuel cut off at 8200rpms, and I believe that the MT PW0 is the same. The AT PW0's revlimiter is early... between 7400 and 7800 rpms. Both have a speed governor at 112mph. Is that the info that you were looking for?

thats exactly whats I am looking for, I have 2 PW0s and one PR3, when I opened the 2 PW0s, it said "MT" on the smaller circuit board, but when I opened the PR3, it said something different like "AT" on the smaller board, for sure not the same as the other two, PW0 seems to idle better then the PR3, this is why I am asking, thx.

 

my b16 pullout has a 1 million (integra) code, with an S1 trans, and a PR3 ecu.... i think both the crx and the integra got the same ecu as i have seen 5 million (crx SIR) pullouts with y1 trans and pr3 ecu. i don't have any idea where pwo's come from. oh well. where in st charles are you?

 

I do know that pr3's are more readily available for rechipping then pwo's. Otherwise they are quite similar.

peace,

I'll have to say you're wrong on that portion of your post. The PR3 did come in an Automatic trim, because I bought one not knowingly. The rev limiter was hitting alittle passed 7000 RPM's.

 

there are both MAN. and AUTO of both ECU's. but to strainten it out:

PR3 = XSi Integra
PWO = SiR CRX

 

my EF9 came with a PWO, but then again, it was reprogramed by spoon, so I don't know if it's the original ECU

 

PW0 is the ecu for Civic/CRX SiR 5 million series B16s.

 

i am about to swap my b16a in and i have a pr3 how can i tell if it is manual or auto?

 

PR3 = 8200 redline... needs 2 O2 Sensors... Intagra XSi
PW0 = 8000 redline... needs 1 O2 sensor... CRX SiR

 

Everything's pretty much been said- one thing though, if you're considering getting some reprogramming done, the pr3 has more programs available I believe, though there are some for the pw0 as well. I've read the auto can only be reprogrammed to 5 speed specs on Locashs site. Other than that looks like yer good to go.

 

There are A LOT of programs for PR3's the PWO has about 2-3

 

They both came in Manual and Auto. I know because I have auto right now with vtec at 4400 and fuel cut at 7600.
