I have a 98 Civic EX with a B18C1 swap in it. What would I have to do to make the OBD2 P72 work in my car? Do I have to do some re-pinning?

Thanks :???:

well 98 civics are obd2a and I don't know if your p72 is obd2a or obd2b if is obd2a you should have no problem if is obd2b you will need a adapter harness that converts from obd2b to obd2a.

Im thinkin the OBD2 P72 is screwed up some how. I have a P28 that I was gunna chip and get the harness for it. I think I can get an OBD1 P72 and then get a harness. Not sure what to do yet. I dont want to get the OBD1 P72 and chip it if Im going to have the same problem.

What kind of maps are on that chip? Got any specs on it? Id like to run a stock base map with out sensors that are not needed.

I'm not sure since it came with the car when i bought it, but the previous owner said one chip was tuned for boost on pump gas;the other on race gas. i also have a jdm p13.

I put my P72 in my girlfriends 97 Ex and it worked fine you must have the later model P72 if it doesn't work for yours......

With my P72 I keep blowing the alternator fuse keeps blowing then all my codes start popin up. 20 is one of them. Thats the load one. I Put in a P2E ECU (VX I think) and it ran like ass but no more fuse blowing and I was able to drive the car. The P72 did look like it had gotten wet before I got it. Not sure whats up. I have a perfectly good running car with some kind of small problem.
