The front sensor is wideband while the rear isn't, so I'm not sure the "reading rear to confirm front" with the stock sensor is meaningful. I'm not sure why you need a second wideband, but it'll work.
Because I need to have lambda alarms when racing...I have had problems (too lean) because of the fuel pump...that I changed.
MazdaEdit read the information but I cannot race with a pc onboard.
I was looking for something able to do that via OBDII, PLX for instance, but the obdII model is out of stock and I'm not sure it is able to do that because they sell an AFR module...
Any idea?
Where do you installed it?
Drilled a new hole in the collectors or placed it at the place of the narrow bad o2? (the second one seems to me too far away).

my setup is custom ...but no reason not to put it where the existing 2nd o2 sensor is .
I also have an aftermarket Wideband in the bung on my midpipe (for an AEM UEGO dash mounted gauge). Readings are slightly different than the stock wideband on the manifold but the difference is minuscule. Flash tuned the CEL away.
