Ktuner V2 Can't find AFR for layout

I am using the 11 text layout with the tach in the middle, but I cannot find AFR on the readout options. Is this something I have to add while connected to the PC? I can find all the other most popular readouts like K Cont., STFT, LTFT, Gear, TPS, IAT1 & 2, ECT, etc. Is it labeled something different than AFR when your are in the layout options?

It's the 02 option...

Thanks a lot! Should TC Pressure match the PSI reading from the PSI gauge on the dash? Or should I use one of the other pressure readouts and adjust for the ambient pressure in my location? Again, I really appreciate the help!

TC Pressure is at the turbocharger. MAP is at the manifold. They're absolute so you'd adjust for any elevation changes to determine relative pressure.

Is there any guide for safe margins? For ex ETC should be lower than 100c degrees, knock should be lower than 0.75 etc. And what do those mean. A guide would be awesome.
