Intake Air Temp Sensor for Power FC

[motronic]

Does anyone tried or know how to install air temp sensor for L Jetro Power FC?
It seems that if you look at the menus and sensor data the air temp input is available although not connected since the stock SR does not use air temp sensor. I know that on RB26 they have one and supported by the PFC too.
The reason I want this is if the functionality is available then air temp is good thing to log (for example to measure intercooler efficiency etc) and perhaps opens up for spark correction due to air temp.
