Temperature Display

[Kevhunts]

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

Well, now that we have some "real" world input, I believe you're right.......... I used to believe I was riding a tall white horse, but alas, it was just a pony. :-[

OK I cannot argue as I do not have the S10 yet. But on my ST1300, the temp Gage is fairly close to ambient checked against local weather on the smart phone. Maybe a degree or two plus or minus.

YMMV,

This is also the experience I have had with my FJR1300 (and my previous ST1300).

It will be good if the SuperT does the same, but it does not look promising from early feedback....

I'm not near my bike and won't be for awhile but I can see if I can change from C to F - I'm pretty sure is the same way you change from MPG to l/100 or km/l

 

[RMac]

Don't think the Euro version S10's can show anything other than Celsius and L/100km's. The UK bike has a few more display options I think, such a MPG, etc..

Other than that I have noted that displayed airbox temp is easily 3 to 5C higher than actual outside air temp even when at cruising speed. In fact we have -20C here just now and I just cold started my bike in the garage (unheated) and it read -3C!! Sorry, now way airbox temp can be +17 higher than ambient. Guess the temp sensor is cheap rubbish or no-where near calibrated or both. I find this a dissapointment. Outside air temp is what I need to know, especially when temp slips down to 0C! On a bike like this I expect a temperature reading that is at-least accurate to within +/-1 to +/-2C...

Is it a problem with accuracy of the temperture measuring sensor, or merely the location at the inlet of the airbix? Seems that relocating it to where it would see true ambient might be in order.

On my R1's and FJR the temp is very close to ambient and they are all taken from the airbox. I had the same WTF? reaction but in daily use it proved to be quite accurate (except for at stops, etc.). Probably be the same for the S10, when on the road at speed, it'll be accurate, off-road and/or moving slowly, not so much. 8)

as stated earlier in the post - air box temp sensor is for ecu engine/fuel injection management. basically so the ecu can calculate air density and apply the right injector pulse duration. interesting that it is a rider sellectable data readout.

This sounds like a cost cutting thing - Yamaha had the intake temperature sensor already, so writing the software to display it was very low cost, much less than rigging a separate ambient sensor. My expectation would be that at speed, the intake would be a VERY close approximation of ambient, but I have no experience with such a system. At least they gave us something - I've ridden a few bikes with ambient sensors and it is a surprisingly useful piece of information if you ride in cold weather where you can see the temp drop danger-will-robinson-black-ice-potention levels in valleys and the like.

There is a lot Of cost cutting in the S10 - intelligent cost cutting, but cost cutting none the less.

intelligent cost cutting, but cost cutting none the less.

Well these days that's probably not such a bad thing. Then we can all lard it up with expensive stuff at our leisure. As long as the basic chassis/engine/suspension package is there, we can each figure out what else we may need or want. 8)

+1 20valves! My St1300 has an air temp feature that I am pretty sure is actually for the ECU to use in calculating fuel delivery. As long as it is in the ballpark that is good enough for me.

IIRC on the ST1300, the temp sensor is right at the front of the fairing, as far away from the engine as possible.

On the S10 it is (as already stated) in the airbox. A bit of a disapointment, but my experience of it is, that in town it is virtually useless due to engine heat. On the open road it is better but it takes quite a while to reach ambient after a stop. On a long run it was close to actual.

It may have been on the ST1300, I don't remember. Others have said that the sensor is on the airbox on the FJR - and if that's the case - mine has still been very accurate.

Yes, it was fastened to one of the front inner fairing panels on the ST1300. That is one of the panels that some owners removed to get more air to flow around the radiator and reduce heat to the rider. In that case, they would zip tie the sensor in place. I don't know if it was used by the ECU on the ST1300, but doubt it. I can check the wiring diagram the next time I am at the shop. In any case it was ambient air temperature. The manual on the S10 refers to it as intake air temp sensor and it does have input to the ECU.
