Mind you, they often have more than one now,
some may have two sensors, one for the gauge, and another to send data

Inlet air temperature gauges are used by ECUs, I do know that - don't
suppose it's a bad idea to let it know about coolant temperature either.
<heh> Make it *properly* intelligent, and prevent the driver flogging
the beast until it's warmed up, that'd be the way.

Well, there's usually intake, coolant, oil and ambient sensors nowadays.

Figures.

There's even altitude as well.

Impossible, without a link to GPS for calibration; not to mention
useless. What they actually have is barometers - capable of providing
height above sea level information when calibrated, but not otherwise.

But what they do do is tell the machinery what the ambient air pressure
is, and that's dead useful to know regardless of altitude.

Mine has even got an exterior temp
sensor, interior temp sensor and a sunlight sensor too.

I want a Laverda Jota. It's got points and a coil, I understand. No
chance of it being knocked out by one of those EMP weapons.

Or I could be slower and more sensible at get one of the new
Cranfield-engined diesel bikes - the civvy version will apparently have
a mechanical fuel pump just like the mil spec model, so it'll run
without any electrics at all.

The average temperature gauge seems to be built into the thermostat
housing where there's no chance of the coolant getting heating up
without the pump running. It seems to be standard.

I must admit, I haven't seen many bikes with temp gauges - I've owned
two with liquid cooling, and neither had one.

Not even an over-temperature idiot light? Rebecca's SV650's got one of
them.

Nope. Neither the BMW K100 (some of the later 16v models did) I had, or
the FJ1200, had any kind of temp warning.

Coo. Well, well, well.

Trouble is there's too many ways to do this,

<puzzled> What makes it trouble, there being lots of ways of doing it?

The trouble comes when they put them in the wrong place in the event of
a failure.

Ah - yes.
