Hard to say. It depends on the algorithm used by Mazda. Total average of past driving or weighted average, more on recent driving.What style can it determine if multiple people drive a car? The missus's driving style is different from mine so the system must wonder why sometimes it is driven harder [e.g. more aggressive acceleration/braking] than others [using it for a gentle coast to/from shops]
Been there, done that, when disconnecting the battery for two months while snow birding. I detected no difference.If you disconnect the 12-volt battery to reset the AT to the factory default values, you will quickly see the difference between the "learned" and default values. That result by itself suggest strongly that the transmission learns. Ed
There was a transmission repair. One would expect a very different feel after the fact compared to when it was operative but on the brink of failure with those "deep learned" performance settings. I see it as a case of the second driver having been accustomed to how it was performing before it failed. Even if it is now operating more optimally, some folks don't like their cheese moved. That's the more plausible explanation than somebody having else having driven it 100 miles.We run into this often in transmission repair. Someone picks up a car, drives it gingerly for awhile, someone else gets into and complains about shift feel.
On the other hand we have a driver of a 2020 CX-5 NA vehicle and others who say otherwise from personal observation. I'm not alone. There are plenty more links that would agree. When somebody says 1000% it strikes me they have something to prove.Lol .... On one hand, we've got a 1st person industry insider who does drivetrain R&D and tuning professionally -vs- Googling a web page from Australia on the internets (which may be 1000% accurate I have no idea)
My money's on 1st hand professional knowledge guy
I'm enjoying the thread and learning new stuff.
The chart attached to your post demonstrates nothing regarding the issue at hand, nor does the pervious chart you posted. That shifting will vary based on conditions or driving style in the moment is not being debated. The charts say nothing about cumulative adjustments for driving style. For the typical driver there is no consistent driving style not to mention, again, a vehicle regularly driven by multiple drivers.I do drivetrain R&D and tuning for a living. I see daily what happens with the actual programming from a variety of OEM manufacturers and suppliers. The Skyactiv Drive family is one of my all time favorite units and I am heavily invested in its future. In the next few months with new software on the market it will be much easier to show what is going on inside the TCM on the Mazdas in particular. Many transmission family's quite literally learn. One example on the market right now are the ZF 8/9 speeds that Chrysler uses. They have 90+ default maps that it can choose from on any given time and then applies a neural network that is trained from the factory to literally learn behavior of the driver. The network learns within set parameters and is constantly changing, with the right equipment you can watch it. Its a fascinating process. Screenshot is from a Hellcat I'm currently working on.
I'd like to see that science. Common sense says there is great variability in driving--the route, the traffic, driver disposition, from one minute, hour or day to the next.Regardless there is a huge consistency to how people drive and a lot of interesting science behind it. Ill post when I can with what I can.
