How would one go about hooking up a wideband O2 sensor so logging with tunerpro rt?
from what I read, option 1: I need an immolator with a extra input.
option 2: use the original nbo2 wire and change the ADX file?
Option 3: ??

This pin B16 is on the ECM board? I will find it.

Yes, Thank You.
I looked at the wire diagram that is listed and I am going to add a bung so I can have two O2 sensors in.

Thanks Dave, I have had it in for some time now.
There is a difference in my readings, wide band reads around 15.5 when BLMs are at 128, not sure if that is right.
Truck runs good, but i would think it would have more power then it has or just wish full thinking.
I worked the math with numbers from my WBO2 instructions numbers

If there were no mistakes in the figuring you're good to go... I know ha ha. I thought the same thing that my math was good, but numbers never were right at first. Redid the math more carefully with help from a few posts eagle mark posted and like magic everything started to agree.

The readings I was comparing the BLMs to are the WBO2 gauge it self.
Idle BLM 128 WBO2 gauge fluctuates 15.5 to 16.5, driving is about the same.
I posted some WBO2 closed loop tuning results, post #8 in this tread: http://www.gearhead-efi.com/Fuel-Inj...g-Dyno-Results
