Is there any way to increase how often this sensor updates? I will sometimes drive for 10 minutes before the outside temperature updates. This causes me to have to manually set the climate way up or down to get the inside temperature I want. (Oh, the horror... I know)
Outside temperature sensor...

While it play some part in the climate controls working how much do expect the outside temp to change in a span of minutes?
There is a cabin temp sensor as well that should be on the dash to the right of the steering column. You should see a couple wavy lines on the trim panel.
That being said I do feel that the climate control is a little wonky in my car as well. It seems to swing somewhat wildly from plenty of heat to a/c and I have to adjust the temp to stay comfortable. I have had quite a few Fords/lincolns with auto climate control that didn't have this issue

I guess I didn't make that quite clear. I mean from the time you start the car to the time it updates the outside temperature. For example, I drive to work in the morning and it's 40 degrees outside. When I get in the car for lunch, it may be 65 degrees, but the outside temp gauge will still read 40 for about 10 minutes. During that ten minutes, the heater will be trying to heat the cabin based on an outside temperature of 40 instead of 65. A black SHO in 65 degree temps doesn't really need heat, but if I leave it on auto, it will go crazy trying to heat up. Like I said, it's a minor inconvenience.

Funny, Not that I drove my car that much when it was cold outside BUT I don't think my heat ever turned on, it always seemed to be blowing cold. But then my temp is set at 68 degrees. I used the good tint so I will be curious how warm it gets this summer.

The real question is what is the in-cabin temperature at the time. Ambient temp doesn't really matter. It could be 40F outside but sunny. Parked in the sun, inside it could be a toasty 80F. So that sensor is what I would check.
I still can't find any info to corroborate that there is a delay between engine startup and sensor update, so other than checking/cleaning the in-cabin temp/humidity sensor, I dunno. Maybe try setting MyTemp and see if that changes anything?

I don't know how to adjust the outside temp sensor or even if it can be adjusted. You might just need to replace it. HOWEVER, it has nothing to do with your climate control. That is dependent upon the cabin temp sensor as others have said.
i'm with OP, my outside temp sensor will sometimes be stuck on the morning's cold temp and when I get in the car in the afternoon. it will still be blowing the heater when it's 75 outside and has been sitting in the sun (so it's probably in the 90's in the car). It doesn't happen very often but when it does, it's annoying.

Information like vehicle year and HVAC system type would help. Cabin temp sensor typically is the over riding sensor for climate control. These sensors on many make and models logic lock, so the remove B+ cable and drain to ground may be a quick easy fix. Even if you replace the sensor, a battery cable hard reset may be required to get the system to refresh.

So I was thinking about this today, I'm not sure why, because I have much more interesting things to think about including what wheels I want on my SHO but here it goes. First does anyone even know what the outside temperature sensor is for, there seems to be an assumption its for the HVAC but it would make more since that it helps the computer control the motor, Second question is if it does have to do with HVAC does your settings have anything to do with its function. You can use outside air for the system or you can re-cycle the interior air. if your recycling the interior air the outside air sensor does not even apply. Anyway just my thoughts.

as my signature shows, it's a 2014. i have dual zone climate control with control through the MFT screen.
the problem happened again 2 days ago. it was 48 degrees when i got home in the morning and the car sat outside until i got back in the car in the afternoon. it was 79 outside and really warm in the car. Car showed 48 degrees on startup and didn't change at all during my 5 mile drive. HVAC was blowing warm air, the AC light on the dash was not illuminated. I keep the HVAC set to Auto at 71 degrees. I had to switch to manual settings to get the AC blowing. On the drive back home 30 minutes later, the car showed mid 50 degrees on start up and gradually increased to 79 and Auto HVAC mode work as it should.
If anyone can show otherwise, my experience shows the outside ambient temp sensor controls HVAC auto functions, or at least overrides the supposed interior temp sensor.

OK - So I did experience something very similar the other day or not similar at all I guess. It was cold out side about 67 degrees but it was warm inside the car, I would describe it as uncomfortably warm. It took a long time to cool inside of the car down and the fan was on low. That being said it did update the exterior temperature on the SYNC pretty quickly and often. I assume since my temperature is set at 68 degrees it was reading the outside temp and using that to determine what to do with the automated climate control. So what I am saying is I have no idea how the HVAC system works.

I still have not noticed this beyond the fact that now that it's been warmer it does tend to warm up some on my hour long commute. Doesn't seem to be out of the ordinary. I don't feel this has anything to do with the issues with climate control since I have them as well. I've never owned a car including a bunch of Ford/Lincolns with climate control that has such a mind of its own. In the winter I had to always adjust and now that it's getting warmer same thing.
