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.
