Coolant temp ( as the Rs doesn't have one )
air temp 1
air temp 2
boost (map)

These are the four I will want to see when I instal one on my engine.

so you have an inlet air temp sensor in the Maf so depending on your filter set up this should be close to ambient and a second one on on the throttle body elbow after the charge cooler / intercooler. You want this as close as you can get it to ambient. Lower would be nice but unlikely.
