What's the utility to know airbox temperature?
Do you want to read the output of the AIT sensor? If so, a Tuneboy or TuneECM maybe?

In ST the display shows either engine temperature or airbox temperature. Not external. I don't understand the utility.

Hmmm, I thought it read engine temp until the bike is started, and then it reads external temp......

i think this is wierd that it is measuring and displaying the airbox temp. Unless, this is close to the ambient air temp coming through the intake tube. Hmm!!!

Airbox temp? Huh, that is where the sensor is?

I'd wondered what purpose the air temp has for normal use as I cant use it for indicating actual temp as the engine heat soak soon has this at fair few degrees higher ie the only time it does display ambient (outside) temp is at cold start. Hmm maybe more use for those in hotter climes as it could indicate onset of power loss due to air intake heat soak?

All fuel injected bikes measure intake air temp and it is the same as ambiant temp when your moving at any speed at all.

Exactly. The temperature of the intake air is required to determine how much fuel to inject, since air changes density at different temperatures. If you've ever heard the term "fuel map" it is basically a matrix of air temps and engine RPMs that tells the computer how much fuel is needed at that particular instant for the engine to run.

What I want to know is, will the temperature be displayed in Celsius or Fahrenheit here in the states?

It certainly is but do we as riders need to see that on the dash? actual air temp would be more useful,.

What's all this then. The XT1200Z has two functions that display temperature. One is the air intake temperature .... it's the ambient temp monitored for engine management. It's displayed in degrees Celcius/Centigrade. The other is the coolant temperature. The two modes are switchable along with instantaneous fuel consumption and average fuel consumption all are displayed, individually, on the top function line of the instrument panel.

I believe that once underway, you will indeed be reading the "actual" ambient air temp. It may be a degree or so off than if the sensor was mounted on the top of the fender, but is should be fairly accurate. The only time it should drift is while stopped with the hot air of the engine being drawn in.

I would think that for the states, the temperature will be able to be shown in Fahrenheit. Most modern bikes with some sort of LED< or LCD screen can easily switch between the two. My Honda ST1300 could do both at the push of a button.

In the owners manual says the temperature indicator shows either coolant temperature OR air intake temperature.

Temperature here is show in C and the manual doesn't show how to change this. But this an European model...

You can believe what you prefer but from actual riding of my own XtZ1200 its definitely not close to ambient so its more an muse rather than a useful rider aid imho

This feature is also like the 2006 FZ1 I had. It would read the coolant temperature or the air intake temperature, a feature I never ever could think of a need for. The air intake temperature is a lot hotter than the ambient temperature due to that air being warmed by the engine. The display will read in C or F at the press of a button. :)
