Upstream or Downstream o2 Sensor for closed loop

Hey,

It’s been a while since I’ve looked at my smanager and and am currently not near my laptop, but I believe Im currently running closed loop with a wideband voltage target. If I ran a narrowband for closed loop would that be more efficient? I find my AFR’s at idle/low load a little inconsistent.

If so should I order upstream or downstream narrowband?

Thanks for any input!

If you have a wideband then running closed loop with it should be the best option.
