The reason I ask because I need to get either a PR3 or PW0 non-obd vtec ecu, so I can toss the POS PM6 its running on now. None of the places I've searched tell whether the ecus are automatic or manual, so I'm assuming there is no difference between them. I thought it would be best to ask here first before spending my money and getting hosed on an ecu I can't use.

Thanks,

 

I think the auto rev limits at 7600.

 

Ok, so that would mean there are auto PR3 and PW0 ecu's. Thanks.

I take it they should cleary be marked MT/AT on the side of the case then, correct?

 

I don't think there marked but, the part number should be diff.

 

BUMP.

How can I tell the difference between auto and manual ecus?

 

on the tag, it have a 3 digit code that starts w/ a J. it is the bigger font code.

j50 and up i have found to be AT

j05 is usually MT

basically lower # =MT

or bust the cover off and look on the board it should say AT or MT
j50 or more =AT

 

Hmm, that doesn't really help me goin by this pic. I don't see any J. Are there any other ways to check without cracking the case open? I'm trying to avoid buying an ecu off of ebay, but if I have to I'd like to be able to identify the proper ecu by pics alone.

Thanks

 

I am having a f-ing brain fart..........

I would put MY money on its a MT

my pr3 says: xxxxx-pr3-J09

****, I dont remember what it is on pwo's

sorry

cmon guys help

Np, thanks anyways.

BUMP.

 

If there are any PW0 auto ECU's they are insanely rare.

Over in the UK where we get the UK PW0-E00 and the JDM PW0-000 I cant think of anyone with a SiR CRX that has an auto tranny installed.

If you get a PW0-E00 it will be manual, the UK market didnt get an auto option.
I dont think the JDM market got it either, but Im not 100% on that, just know Ive never seen a SiR with auto tranny imported to the UK.
