is there any way to make a single wire pre-obd B16A O2 sensor work with a newer obd1? SIRII four wire O2 sensor

please help

I made this for a b18b going into a 92 cx. I think it should work for you.

your pic doesnt work

that doesnt help im going from a four wire O2 sensor to a one wire

i would vote against the idea, 1 wire guys convert to the 4 wire for a reason. not the other way around.

Hi there, I'm assuming this pic you have is to go from the non-obd dual 1-wire O2 Sensors to a single 4-wire O2 Sensor. Unfortunately the picture doesn't work. Looking at the diagrams it looks like I can easily add the 4-wire into the header, seal off the extra O2 Bung, and then wire up the 4-wire to match the single wire with the addition of a power wire. is this correct?

You *can* make a one wire 02 sensor work on a ECU that reads a four wire, but it will not read the same and go back to the base maps on the ECU.

When I says can, I mean you can wire it to it, but it will not work right and your idle maybe effected.

No, I'm keeping the Non-OBD ECU, just looking to convert the dual 1-wire O2 Sensors into a single 4-Wire O2 Sensor utilizing the non-obd ECU.
