They are both fully open when the car is off. Sorry if my description of the issue wasn't clear.

You need the memory package to get the mirror tilt in reverse I published the settings for 718. Very minimal tilt because the mirror don't store the saved positions. I tried my settings on 992 GT3 Touring and they did not work.

So any updates on start stop? 5 years later and nobody really figured out solution? 
)
Maybe the approach should be changed, instead of trying to disable it fully we should just look for enabling "remember last mode". I was able to play with launch x431 including 3 settings provided in this thread, however it fails on settings #2 and is unable to write it. Writing the first setting to DME will result in "auto start stop" failure message.
Another approach is trying to find an option that sets a minimum temperature for start stop to operate and set it to absurdely high value so it never triggers. Something like this was possible in older porsches.
Another way how it could be perhaps automatically disabled is via navigation. As many of you perhaps know MIB navigation can be given root access (that's how people enabled "fullscreen" carplay and how you can get newest maps for free), which means in theory you can send signals from the PCM to modules in the car. With root you control the whole PCM.
PCM has a button of start stop integrated so it has a way to send a signal to disable start-stop. If one can find how to send a signal programatically (reverse enginner PCM app) to the car so it looks like coming from PCM... then it can be easily automated by adding an extra script to the PCM navigation which would start after the boot. This script would send a signal to disable auto start stop without user interaction, while the car modules would think it's coming from user click. Easier said than done, but that's like the last resort if no way is found using PIWIS.
Just throwing some ideas, hopefuly someone finds a solution.

Nobody has discovered anything via coding, but other known 'solutions' include: a) use sport mode, or b) turn passenger A/C to cold which will keep compressor on and inhibit ***, or c) get a tune from M-Engineering.

I'm following this video from Mars
https://youtu.be/9vlGUX42A54?si=0oCpzEZqN0cxFC0p
I get everything, hit write then goes through the motions, then I get an error msg saying it couldn't write. What gives? Thanks.

Maybe Mars can chime in. I have coded many cars and got that error too sometimes. If you go back to the previous screen and come back it would sometimes save the changes. Try to make one change at at time. Always check the value that you changed. This happens a lot on 992.

If first, It seems that their device is sending CAN commands after the start and just imitating what user does programatically. If it's *** icon is completely erased from PCM then they're sending coding commands on vehicle startup, the same way we are sending them using piwis when trying to code it out in DME (then they're restored back to default state after vehicle restart
)To develop something like this one would need to to start sniffing on the CAN bus and try to find what commands are sent once you press start stop. Then you program your dongle to send exactly same commands the moment car starts.
If there was one such dongle, for start stop only i think there'd be many buyers.
