• There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software.

2021 Outside Temp Gauge Issue

We have two 2021 RTLs and both it seams that the outside air temp are off by about 5+ degrees. Also when sitting still the temp goes even higher. Has anyone else noticed this. Is there a fix or is this just live with it?
 
It's not an 'Outside Air' temperature gauge, it's the temp detected by the sensor mounted under the tupperware somewhere near the air intake, so it's getting some heat from the engine, reflected heat off the road surface (if it's a hot day), some protection from any breeze/moving air, and so it's showing you a temp that's WAAAY CLOSER to the Engine Air Pre-Intake temp than anything else!! :rolleyes: Some marketing guru probably thought it'd be a good selling point to show ambient temps on the dash, but the BRP bean counters wouldn't allow the dollars to add a sensor to give that (and it would probably add to the retail price!) so the decision was made just to use the temp sensor already there, even tho it doesn't really show ambient temp! :gaah:

You can either ignore it; get used to it reading high & going up whenever the 'under-tupperware' temp rises; or if you are really keen, you could locate it & move it away from the under-body/air intake location.... but if you do that, it might mean the engine computer thinks the intake air is a bit colder & denser than it really is when it gets sucked into the important bits, which could result in the engine using a bit more gas & maybe running not quite as well as it could?!? :dontknow:

Me, I'd live with it as it is, knowing it's usually going to be somewhat off the 'official' temperature, but then those temps are usually taken from inside a box/Stevenson screen that's often located sorta in the shade or still air somewhere, so are they a real reflection of the temps you're ryding in?? :p

Ryde More, Worry Less! :ohyea: And don't think that temp display is necessarily showing you anything gospel! :lecturef_smilie:

My 2021 RTL does the same… sometimes reads a little high as compared to the reported ambient temp… but so did my Gold Wing trike.
Peter’s explanation sums it up nicely.

My 2018 RTL is the same.

It's a Factory Issued/Undocumented Feature that's been identified in all Spyders with that temp display on their dash - there's threads & discussion about it dating right back to the early days of this Forum. So unless someone's modified their sensor position/upgraded the software/jimmied the gauge, etc, it doesn't matter what year or model Spyder they've got, they're ALL pretty much the same, even if the owner/operator hasn't really noticed - yet! :rolleyes:

On the 2021+ RT, the sensor is located under the front right side body panel next to the hood. You can move it to a better location. There is some extra length to the wire. The sensor is black with 2 wires and clipped to the frunk framework.
 
We have 19 and 20 F3L's. Our gauges are consistently 2 degrees apart. I always drive at the front of the pack.

Outside temp will vary up to 5 degrees based on outdoor thermometers. Once again, I think it has to do with the OD thermometer location. Direct sun can play a big part.

I ignore my ( 2014 RTS) because it is so small as to be useless, ( so is the clock, But I've added one of the dash mount.

Probably not applicable here. But my 2008 temp sensor was zip-tied out of the way from the factory. It was supposed to be re-located during dealer set-up to a more appropriate place farther forward and within the intake airstream. When I discovered this and mounted it where it was supposed to be, temps got much more stable and reliable. The more accurate readings also helped the engine run better. With readings too high, your engine will tend to run leaner.

Turned out this was a common corner cutting issue with dealerships on the early models.

In my humble opinion.....don't even bother showing that useless number on my dash! Give us a Navi system or even a cup holder instead.
A temperature gauge should give you a true ambient temp..... not a temperature somewhere in the bowels of my Spyder.
Just sayin' .........
 
I have a 2021 RTL, same issue with temperature going very high when your setting in traffic, once you start moving, comes back to being relatively accurate! I am usually riding on nicer days, so outside temp. really doesn’t effect my ride! Just my thoughts…
 
mine reads about 10-20 degrees high no matter if im stopped or cruising down the highway.. I just got the BUDS 2 system, I want to see if it can be calibrated to be more accurate cannot wait to dig into it.
 
The sensor needs to be moved or it needs to be renamed to under Tupperware temp gauge. It is definitely NOT outside air temp gauge.
 
Wait till he notices his clock

:roflblack:



Are they really STILL doing that?!? :banghead:

Mind you, without something else showing the 'real time' (like the Garmin GPS that the earlier up market model RT's got) to provide an accurate & in-your-face comparison (if you can read anything that small! :p ) it's likely to take a while for anyone to notice that the dash clock is running on a different time scale to everything else in the universe! :rolleyes:
 
My husband has a 2016 F3-T.

I have a 2016 F3-S.

Sitting side by side or riding right behind one another, my S always reads hotter. Sometimes by as few as 2 degrees, sometimes by as many as 10 degrees.

Kinda disappointing, actually. I was rather pleased with the feature until I realized how inaccurate it is.

Funny you mention clocks. I'm highly impressed with the accuracy of the clock on my '20 RT. Aside from semi-annual adjustments for DST/ST I've only had to adjust mine twice in nearly two years. The clock on my old '14 gained about a minute-and-a-half every WEEK!

We can probably all agree that Spyder temp gauges are way off the actual temp, and there's probably no fix. It's one of those little things we live with. No biggie in my book.
