spacing between WB & NB sensor on exhaust

[radsan]

So I manage to get a wide band sensor installed on my car,but I wonder what is the minimum space betwen the NB & WB sensor?

the reason I ask this is because my WB reading is not stable some time go very lean & when idle hovering on 14 to 15 ....

I install my WB about 10cm after my NB does it affect the reading?or should i put before my NB? the reason I put after is because easy to install,more space after my NB

Please advise.

With them being that close, exhaust flow to the second sensor is going to be disrupted so yes you will see a difference in the quality of the readings. My suggestion is to offset them so each gets a full shot of exhuast gases.

i would have thought they should be opposite each other.
That way there both getting the same shot of exhaust, at the same time.
Thats how i have mine, but mine is still in the build stage.
