Thanks for the response doc. My main goal is to log as much data as possible through the Zt-2. Don't see the point of buying such a tool and only using it to log boost and AFR. Then again, I don't want to spend extra $$$ for sensors if I can tap into existing ones already on the car. Boost, IAT, and fuel pressure are the ones I'm concerned with after the ever important AFR. My friend has a welder and a nice shop to take care of the O2 bung install.
