It plugs into the OBDII port and gives a significant amount of info - but not the outside temp. The "intake air temp" is probably the closest, but it's not true outside temp.

Interesting
But... if it reads from the ECU, that mean the ECU is already set to compute thos infos... why it doesn't not also display them on the cluster it has to be plugged or something

Not sure what you are saying. The ScanGaugeII only reports what they have programed it to show.

well, i guess it's the ECU who computes, say, the MPG, so the ScanGauge only display it. Then what's missing to have this information directly displayed on the Yaris cluster ?

Probably some kind of programming, it seems that the clusters for different markets all have different features, and inside, some have different LCDS and different EEPROMS, there's really no telling how we would enable these features, but I'm sure you'd have to reflash one or more of the EEPROMS to do it. From what I've been made to understand, the plugs on all the liftback gauge clusters are the same, it's the clusters themselves that are all made differently.
