Do those of you noticing the problem have AWD or FWD? Since outside temp is one of the sensors the AWD system takes into account, that may be a factor
AWD only with turbo.

The issue then seemed to be "variable power delivery", punch it one time and it works, punch it the next and it doesn't.

All we have so far is a lot of talking. If one is so concerned with the performance of the car, they should test the car to see if it exhibits the behaviour and record it for posterity.
I had done my own testing earlier in this thread and realized afterwards that my testing was not ideal. I think the best test to determine if there is an actual power loss would be to test WOT acceleration while at a cruising speed in temps above 20F, then again in temps below 20F. Get the car to 25mph, then go WOT and see how long it takes to get to 50 or 60. Repeat in warmer/colder weather and compare. A test like this would mimic real-world operation (highway merge) while a 0-60 acceleration test would not.
I dont think I am. The 2.0 had a 0-60 of around 9-10 seconds, didnt it?
I started the thread to draw awareness to the issue. You dont care/refuse to believe that yours is like all the rest/wont empirically verify one way nor the other, so...maybe this thread isnt for you, specifically?
As Sig said, turbos only come with AWD. But the subject of cold weather AWD contribution has been discussed earlier in the thread and is still a possible causal issue. If there is a software fix to be had, I'd prefer an AWD system tweak than an adjustment that might increase the possibility of oil dilution.
I wonder if the Mazda 6 with the 2.5T (it's only FWD) has the issue?
I did 0-60 runs back to back over the course of about 2 minutes and recorded them. Seems it was 20-21*F in one, and 19*F in the next...weather was perfect for it. 3 second difference.

That kind of a nanny feature would be unprecedented, I*d think. Also, it would be ridiculous considering were talking about a car that doesn*t even have 300 HP.
I'm not some moron that wouldn't notice something like you're experiencing, so please stop insinuating that. My wife's prior daily could not get out of its own way, but even that was not a 10 sec 0-60 vehicle, closer to mid 8 sec's. So, I know from experience what pulling out into traffic with that limitation is like. That is not the case with "our" CX-5 in any temp.
What did you respond with to sm1ke's 0-60 run in his CX-9 when it was below 20f? LINK
Also, you're entitled to your opinion, but not telling others what threads they can contribute in.
The reason why I think it is because of the possible slippery conditions in the cold and not oil diffusion is, in the cold the turbo starts at 55 mph. Even at 55 mph there would be oil diffusion from the turbo if that was a thing. When it is warm you can hear the turbo from 7 mph, in the cold you can hear it at 55 mph.
Turbo whine at 7 mph
Turbo whine at 55 mph
You could try removing the DSC 50a fuse to figure out if this is a TCM limitation or ecu tune limitation. If nothing changes then wheel speed has nothing to do with it and it's all tuning.
Honestly it may not even have to do with wheel slip, but could be from temperature and pressure or something. Then wether its controlled by the TCM or the ECU is a question.
I'm going to just lean hard on Mazda. It's not my place to fix their product. I'm the customer. Not a free engineer or product evaluator. They dont pay me a dime. So I'm confident an issue is occurring, as I've quantified it, and now I'm going to lean on them to offer resolution by way of fixing it, or explaining why it just be so.
2018 CX-9 AWD, outside temps at 2c (36F). TCS off, engine cold.
Here's a general idea of what the road looked like.
Not dry, but not really wet either.
