@JB911

There is also a Rennlist member here that has a PIWIS III setup for sale. (I have not included his username as I have not asked his permission to list it. I can provide folks with the username via PM if needed). If you have a laptop laying around with a minimum i5 processor, 8GB of RAM and 256GB of storage, you can get a PIWIS III Version 42.950 from Mars. He is a GREAT RESOURCE for information. Setup is very straightforward. He can also sell you the VNCI PT3G VCI adapter. And I can tell you that I paid nowhere near the prices listed in your post.

I had an older ThinkPad X1 Carbon (6th Gen) with an i& processor, 16GB of memory and a 512GB SSD. I was able to re-partition the disk to free up the necessary three disk partitions for the PIWIS III software and created a dual-boot system. Using Dual Boot (a feature included in Windows 11), I can either boot to my PIWIS image or my Win 11 image. I have a complete setup that even includes a second USB-C monitor so I have run PIWIS III one on monitor and see other applications (like a web browser or Arcobat) on the second monitor.

I also came across a Schumacher INC100 power supply (100A Flash Reprogrammer/Power Supply – Schumacher Electric) to provide the car with nexessary power while playing around with your new PIWIS III. According to a good friend of mine who works for PCNA, this power supply was a piece of standard equipment at dealers.

Anyway, just wanted to add this one to the list. I'm not trying to be cagey about the supplier, I just don't have his permission to publicize his name.

Yes, I was able to set it to Aero in E mode. No errors & rear center light works. Note, I have a 2023 Carrera T.

Awesome, thanks! My Aerokit spoiler is being painted now. Debating taking to the dealer or doing it myself. What software you using?

Do it yourself. It’s very easy to do.

I'd like to, but the problem with the forums is that there's a ton of info in this post but can't seem to find a single source of truth. lots of individual comments and nothing is consolidated into one.
So if there's a specific comment I can start out at and scroll a bit to figure it out, that'd be great!

Just search for the AeroKit thread. All of us who DIY’d the install have posted there. It’s a 2-hour install max if you have even the most basic mechanical inclination. All of your questions will be answered in the thread linked below.

My bad, I wasn't clear. I'm doing the install myself. Just referring to coding the spoiler portion of it.

Via PIWIS, change the configuration to VM3 AeroKit. Check brake light functionality to ensure it’s working as well.

If you need the official Porsche instructions I can send them to you. Here are screenshots:









Here’s another thread that has coding info and see my last post on what to change to fix the configuration on the PCM screen:

Thank you! I have these instructions already too, thanks to a prior post of yours. I'll look into buying all the required things to get a PIWIS setup at home.

Don't forget to source an external power source to supply a constant 14.2V to the car when doing your PIWIS work.
