I am a new 91 Honda Civic H.B. owner. The car does not have the original cars motor it has the Acura Integra Motor B-18A1 and i am trying to locate a OBD package that will work with that engines ECU. I am aware that the OBD stands for (On Board Diagnostic) but I am having trouble pin pointing wether or not it is a 0, 1 or a 2 so i can buy the correct sofware to Install in the car there for I ccna do my own personnal tuning. I am really interested in the HONDATA but its asking once again for OBD info. so there for I need to know were to look or how to locate the OBD that is on the B-18A1 engine. I am also aware that the engine came from the GS or LS Integra if that helps. Well hopefully someone somewere can help me with this little perdiciment so i can get this thing to the track to see how it runs. Peace and Thanks to all who reply.

on the ecu itself on passenger floor , is a sticker. on that sticker is a code. in the middle of that code is a letter and 2 numbers. example , PR4. find out what ecu you have and ill tell you what its from and what OBD it is.

 

unless im misunderstanding you and you have no ecu whatsoever. check to see if your injector wiring goes through a black box under the hood.
