As with anything, I'm a little concerned about getting scammed out of a little over $1k, but it seems like if this works it's worth my money. Anyone on the forums tried it? @love2020 or @rbrunelle - is this where you obtained yours?

I bought a PIWIS II from them without any issue. Worked as advertised.
Well, the turnkey solution certainly works. It arrived much faster than expected, contents are a PIWIS III dongle, USB cable, Lenovo T450 laptop with v38 and v39 software installed. Looks like it is in development mode because a bunch of German comes up along with English text. It connects to my 991.2 successfully and runs diagnostics successfully, so at least as far as that is concerned, it works. As to adaptations and such - I have not tried it at all. I need to ping the people who sold it to me and ask them if (a) I can take it out of development mode, and (b) I can connect it to a network and get updates downloaded online.

Interested to what they say about your questions (a and b). Does development mode stop you from doing anything or just an annoyance? I’m guessing it will be a no go on the updates.
Highly doubt you'll be able to get updates. You are effectively using a bootleg copy of a $25,000 setup that calls home and verifies stuff if my understanding is correct.

Agreed entirely. More interested to see if it can connect as far as certain adaptations are concerned - again just an academic exercise because I don’t really plan on using it for that at the moment, but I believe that these need to the system to be online. More useful for things like putting the parking brakes into service position, etc. and for better diagnostic scanning of faults. For example, I discovered a couple of faults that were a result of switching out the PASM module - totally benign, but didn’t show up with a cheapo OBD scanner. And naturally because I’m still dealing with the P24D6 thing I wanted to see if I could get more information from the system by using PIWIS. For that I have to wait until I induce the fault again.
What I would like to know is: For the Auto Stop/Start Switch (991.2), Can you change the selection in the software from "Active at Start-up" to "Last Position at Start-up" or "Disabled at Start-up" ?
Crap, I would pay a few hundred buck to get that changed! The 2 closest Porsche dealer will not do it, stating some EPA rule, and I rather not add the "T-Design" aftermarket module under the airbag if its a simple "Check Box" selection that already exists in the cars software.

It’s a bit of an annoyance having to translate the German. However, it appears that version 39.900 is English/German development mode, and 38.200 is English/production mode - you can boot between the two. Regarding capabilities, it looks like development mode gives you the ability to do “coding without rules”, whatever that actually means. I’m not about to try it just to discover that it turns the car into an expensive lawn ornament.

I played around with things a little in simulation mode (if you don’t connect the VCI, you get a prompt to “press F12 to enter simulation mode”). In diagnostics, you can enter the “Coding programming” option after selecting the DME control unit (there are 10 to a bazillion control units depending on the car model you select).
In the Coding programming, you can find the coding value of 642 - START/STOP FUNCTION. It has an “installed”/“changed” column, and if you click on the “installed” it seems like you can make it look like it is *not* installed. And then I’d imagine you would write that coding out to the vehicle. So yes, it looks like you can, in fact, do that. Maybe something an Indy shop could do for you.
See START/STOP function highlighted. Note the no check mark in the “Installed” column, and the pencil in the “Changed” column - that’s because I clicked on it and changed the value. I *assume* this would write the changed value out to the car and disable the start/stop function, but I am honestly not about to test it out on my car.
@enzotcat - Many thanks for looking into my Auto Stop/Start coding question. I am a little confused by the statements suggesting "deleting" the functionality. Maybe I am miss-interpreting your words, yet my understanding was that the software already had the options of how the AS/S system should behave at Vehicle Start-Up.
I pulled the following from another thread, where they talk about using a PIWIS 3 in "Engineering Mode" to make the selection.........

From what i can gather with the Porsche PIWIS u can program auto s/s:
Always ON
Always OFF
Remember last setting
But I haven't confirmed that it has/can be done on US cars....

I can do it in a few minutes. Here is a picture of the screen taken from a 971 gateway module in engineering mode, manual programing area.
as you can see Stop prohibition is a selectable option.

PIWIS III clone, anyone tried this?
