Sorry if this isn't exactly the right spot, but the Nissan section gets very little traffic.
I was hoping to add wideband w/ emulation into both banks of my Nissan Frontier to use with a ProLink. Unfortunately, I'm not sure it's really going to work. The first stock bung is only about 12" from the cylinder outlet, and is directly in front of the primary cat (see picture 1).

The only location within the correct range would be in the midpipe, somewhat upstream of stock sensor 2 (see picture 2).

I spoke to Innovative and AEM (Zeitronix has not responded). Innovative basically reiterated their install instructions, and I have read on other threads here that they have expressed dislike of using NB emulation. AEM suggested I consult an experienced tuner in regards to locating the sensor. That's where I hope someone here might chime in.
Any more-professional-than-me (which isn't much) tuners on here have experience locating this close to the exhaust or alternatively after the first cat? I found a few threads on the latter, but nothing really concrete. Would this be a waste of my time to dig farther into this? Being in MA, I can't even relocate the cat's to make everything work.
All three units I've found with NB emulation use Bosch 4.9 sensors, which are not my fav...I have always stuck with NTK in the past...am I missing a brand that might better suit my needs? If I have to go downstream of the first cat, I'll just add them as separate bungs anyway, and would probably use the Ballenger units instead.
