That's probably because your Goldwing's 'Ambient Temperature Display' was
actually just that, with it's very own sensor that's placed somewhere to give a fairly accurate reading; and it was probably always designed & intended to be used as just that.... ie. a display that shows you, the operator, the ambient temperature!! :shocked: And I'm pretty sure that somewhere in the electrickery that controls the Goldwing engine, there's a completely different sensor that tells the Computers what the air intake temp is.
The display on our Spyder Dash takes its temperature reading from the sensor that, at least initially, was simply meant to provide the controlling Computers with info on the air intake temp for the engine; only someone (in marketing probably

) thought it'd be a good idea to copy those other 'well designed & thought out' driver aids, only do it on the cheap....:sour: So the temperature that we get to see on the dash is showing us info that's been cribbed from that sensor & displayed to the operator as an after-thought.
Which means that when it comes to the dash temp display on our Spyders, no matter how hard BRP might try to convince the gullible amongst us otherwise,
it's NOT REALLY an 'Ambient Temperature Display'!! So at best, it's an ill-advised mistake to treat it as such! :lecturef_smilie:
