Can I use the narrow band wire on my wideband harness in place of the original O2 sensor

I have tried this on my 86 and it throws the O2 sensor code. But if i hook up the a stock one wire O2 i get no code.

It works flawless for me. Car thinks it's the factory O2.

The factory ECU ignores the O2 when in boost.

I'll have to install the adjustable fpr maybe check the screen on the pump and the fuel filter could the pump just be weak?

If I'm not mistaken, you want to be around 11.5-12 on full boost. Any higher is lean, and 14+ is higher detonation risk.
