Great news! Big deal for Mazda to take the time to fix this ECM programming. Months later mine is still totally smooth cold warm whatever.

 

Interesting to me the 22 would have this issue. My 21 is fine and has the same transmission. Why would they mess with something that works? My 20 Frontier had horrible TCM programming from the factory and it took two reflashes to correct, but it was a brand new powertrain so I gave Nissan some slack. It's great now.

 

This is why I responded as I did? There is no one at a dealership and Mazda crop will not divulge who their ECU engineering and development company is? My "guess" remains that it may have been a programing issues from the developer in the process of manufacturing that they later caught. This is why I said that a simple "flash" may have done the same thing as the TSB and subsequent information? It goes without saying Mazda may simply have covered their **** legally.
So unless someone having the problem and has a Mazda dealership willing to do it or better an independent service shop that has a Pass-through devise and the current Mazda programing (not yet available I looked) then we cant even try an experiment.
But hey we have now abuilding number of members that are getting the TSB done and think that "re-programing" was the ticker to happiness. LOL
ECU programing is not hard to understand but I do understand that unless you are into calibrating ECU, PCM, TCM etc., and see the files and understand how several are linked and work as a unit it is easier to just assume and be happy that the problems from some ECU programs and or glitches were corrected?

There are only a small handful worldwide that have even attempted to calibrate many changes in the TCM portion of ECUs because of the complexity of their interaction with each other control over the interior engine and transmission as a single unit. The most I have ever done (that I will mention ;) )is for the most part adjust my pressures tables in the transmission at a target % or the drive-by- wire actuation.

 

Understood. It could be that with the new off road modes they added for 22, they did some reprogramming of the TCM? Who knows? In any event it is good that folks who are getting the TSB done are seeing success. I know with my Frontier it was a night and day improvement with the TCM reflash. It was barely driveable at low speeds with the original programming. And, yes, I know it isn't a CX-5 we are talking about so my experience will be different than with a Mazda

 

I have an electrical/computer engineer friend who loves this type of stuff.
Infatuated with computer data and logs and how they operate in conjunction with other electronic devices.
Before retiring he designed the internal circuitry for CPU chips.
In his home office it was common to see him manipulating data and writing code on three screens at a time.
He can easily manipulate code on everything electrical he buys (or anyone else's for that matter) from his computer hardware, phones, vehicles, drones you name it.
He can run his entire home (lighting/HVAC/etc.) from anywhere in the world including his outdoor BBQ, smoker and pool.
Yep he can control the heat and amount of wood chips when he uses them, in the BBQ and amount of pellets/smoke in the smoker as they both have heat and air density probes.
They even have controllable servo motors for the venting.
I have access to see them on my computer and it's a good thing he lives 3 1/2 hours away or I'd be showing up for BBQ or smoked foods more often.
Built his own remote controlled lawn mower years ago just for the fun of it, put a remote start on his snow blower just to see if he could and he programmed each to work with his phone or his older drone controls.
Designing and building this stuff like this has been his life long hobby.
He was the one who properly remapped several of my racing motorcycles, which allowed me to reach 204mph on my 2006 Hayabusa, which was stock aside from Vance & Hines exhaust, at the old Maine Limestone AFB speed runs.
His wife said if he dies before her she'll never be able to get into the house and no one would buy it because they'd never be able to operate it.
He said he had his heartbeat Bluetooth monitored so if it permanently stops the house would reboot to it's default settings.
Knowing him, it may not be a joke
