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.

If you're not already using one of the TGV inputs, yes, you can run the WBO2 0-5v signal into it. It will then have to be configured in the tune.

You're going to have to have it enabled first...
