What all do I need to do to the HF harness to run OBD1?

SO i need a 4 wire o2 sensor? Where do I get one? And what would be a good ecu to run on a lsvtec? I was thinking p72 or a chipped p28? Can I run a mugen program and bypass the 2nd o2 sensor like on obd 0 electronics? I don't know about 4 wire o2 sensors I don't think that makes sense.

 

You need to run the 4 wire O2 sensor. Find one online or at the junk yard, etc. I would suggest a chipped P28 ecu. They are easy to find and are fairly inexpensive. Again, you can run the mugen program, but sounds like you are trying it for the name and you will ditch those two 1 wire O2 sensors that were on your OBD0 setup. The OBD 1 electronics look for the heated O2 sensor. The 1 wire O2 sensor is not heated.

 

Any picticular car that the 4 wire o2 comes off of?

 

For example: 92+ civic(dx, hx, si), Integra(94+)....

 

any 4 wire o2 sensor will work. the wire colors are just slightly different.

 

60-1EK- Are you local cause I know ive seen you on hondaswap before. Not sure. Probably wrong. If you are thats great. Iam defentily intersted in the harness conversion. I plan on getting one before christmas. It just depends on the pace I get the parts together for a engine thats getting put together for the crx. I will let you know though. Thanks for the help though juice2ndgenteg and 60-1ek.

 

I am local and I have been on Honda swap as well too. Let me know if you need something.
