Question about ECU's
Hey guys,
I just had a question about ECU's. I was a little confused from the Hondata website regarding which ECU's are OBD1 and OBD0. I have a '89 CRX with a B16 swap. I was told it switched to OBD1. Well, I checked the ECU and it is a PR3, but the connectors to the ECU look just like an OBD1 ECU. After searching the forums, I noticed they make both OBD1 and OBD0 PR3's? I just want to make sure this is right?
From the Hondata website, none of their stuff supports PR3 ECU's anymore. Does this just apply to the OBD0 PR3 or the OBD1 as well? Thank you in advance for your help.

OBD1 PR3 exists! From what I understand it is functionally equivalent to a p28 when chipped, so hondata should be able to load all the junk as with any other obd1 ecu it supports. Not entirely sure though.
