I'm hearing different stories about wether the p30 ecu that I'm getting with my swap B16a (SIR II), is OBD1 or OBD2. I've heard that it will be OBD1, so easy to Hondata, but also, I've heard that it is OBD2, so needs to convert to run Hondata. Any one have some insight on what the ecu will be?

obd 1 least thats what mines is and it looks like a lil square lol

there is probably a couple versions of the P30 because it is the same motor through out the generations

90-91 integra XSi (B16) PR3 OBDO
92-93 integra XSi (B16) PR3 OBD1
92-93 integra GSR (B17) PR3 OBDI
Civic Sir B16a (88-91) PR3 OBDO
Civic Sir/VTI/ B16a (92-95) P30 OBD1
Civic SirII B16a (170hp) P30 OBD1
Civic SirS B16a P30 OBD1
civic Sir 96-98/ Del VTEC 96-97 P30 OBD2
99-00 Civic Si/Sir P2T

its something along those lines for B16 ECU i could be wrong on one or two of those .

they come both obd1 and 2. I have a friend with a mugen chipped obd2 P30.
