Superb write up and i can't stress enough how important it is to have a wideband o2 on any turbo EJ. The only downfall is Cobb was forced by the EPA to remove the rear o2 sensor custom sensor input so this is no longer an options with a Cobb AP since the Cobb Green Speed update... (truly heart breaking!)

You can still add a WBO2 signal to Cobb on their NexGen stuff, you just have to get their FlexFuel setup and use the opposite TGV input. We lost the ability to use the rear O2 and it got more pricey.

Yep good call that is the go to move when i have to tune a Cobb car now BUT only works for the cars that are supported by the nextgen flex fuel kits which of course leaves out a ton of the older EJ stuff. ***still nice to have the option though for newer subi's as logging lambda through the ECU is a must imo.
side note: also annoying to no longer be able to utilize flex fuel, fuel pressure and a wideband all at the same time (huge fan of setting up injector pressure differential trims when using fuel pressure sensors). I'm guessing all the apps using the CANbus module will soon have a solution for this though.

I have a wideband 02 sensor (Iwirekit) installed on my car and Also have the cobb nextGen. So by using one of the inputs TGV used by the pressure sensor I can unplug and plug in my wideband in its place and Cobb AP will be able to show data?

when using the wideband input instead of oil pressure you'll have to disable all oil pressure related functions and you will only be able to log/monitor the 0-5 volt output. Use megalogviewer to create a math channel that converts the 0-5v sig to Lambda.
