Can someone tell me the difference between the two. I have a 2001 Integra type R and looking in getting an OBD1 ECU for a HONDATA SETUP S200B. I know HONDATA makes an ECU with OBD2 connector already on it but they dont mention anything about being 2A or 2B.

Thanks

 

You need the OBD2b setup. I have conversion harnesses and Hondata ready ecus if you need it.

OBD2b will cover your 00-01 integra.
