Sorry if this was posted in the past, but i've used the search tool, typed it in different ways and coudn't find what i was looking for. I have a 92 Acura Integra RS with a jdm 1st gen B16a (converted obd-0 to obd-1). Im buying a usdm P72 from a fellow H-T member. I've been running my LS ecu since i've did the swap, and its finally about time for me to get vtec running. Does anyone have a diaghram of the ECU pin outs (picture). Also, since its a p72, it has that secondary butterfly activation for the B18c1 I/M, does that affect anything with my b16a I/M? Any information would greatly be appreciated. Thanks in advance guys!

 

Don't worry about the IABs, even tho your B16 does have them the P72 ECU won't throw a CEL for it or cause you any problems. The downside to th P72 is its mapping is complete ****, VTEC is too low, etc. If you can I would still try to get your hands on an OBDI PR3 or P30. As for the pinouts, just did a search on here... https://honda-tech.com/zerothread?id=395108

 

Thanks. A lot of the h-t members are telling me i should go chipped p28. What do you think?

 

It really depends on what your plans are. Personally I don't like too many chipped ECU's because the maps sucks but there are a few versions of the Skunk that I like. Is your motor basically stock? If your choice was down to a chipped P28 or stock P72 I'd take the P28 anyday.
