Is that the one you can hook up with the torque app? What sort of data do you get from it?
I have the Torque app and a bluetooth OBD11 plug, Have not used it on a subaru but on the few hiace vans and a sprinter I have used it on pretty much any info you want/need is available.
if it has a sensor for it then it should be able to read the data,
on my driving screen I usually have boost,common rail pressure,speed ( gps and speed sensor) intake air temp,oil temp,oil pressure and water temp,
