Been reading through this whole thread those morning - looks quiet exciting.

I do have a question - can this PIWIS clone / hardware do the coding for Cruise Control retrofit in a Cayenne 9PA?

Anyone down this here?

WARNING!

DO NOT upgrade VirtualBox to version 6.1.14. It WILL break the VM.
The VM will fail to start, period. Neither changing VM settings, restoring from snapshots, re-importing the VM, nor performing a clean install will work. The behavior will not change.

Thanks for the heads up, I assume you were able to roll it back to v 6.1.12? I just opened Virtual Box and it immediately asked me if I wanted to upgrade to 6.1.14 so it must have just been pushed out.

You can turn off check for updates in Virtual Box's preference menu which probably isn't a bad idea. Hopefully we can get this resolved ASAP as one appeal of using a VM on a modern OS was having updates for security and glitches.

Here's what I could find for a Cayenne 9PA:

+1. My indy shop is looking for a PIWIS 3 clone as customers with 2019 and 2020 cars are starting to go there for maintenance. Thread subbed.

OBD2Tool sells this but not sure if correct.

Well this is timely.... After planning on at least setting up a PIWIS on a virtual machine, at least in simulator mode, to check it out, I finally decided to give it a go yesterday.

I downloaded VB, grabbed the VM image, and it crashed in about 10 seconds every time I opened it. Now I am running VirtualBox on my Mac, as I would prefer to run on that platform if it did work, and chalked up the failures to being on a MacOS platform instead of say running the virtual machine on a windows laptop. Now I wonder if the problem is simply 6.1.14.

I haven't tried it yet, but for those who need it, here is a link to the deprecated 6.1 build downloads...

I'll post back after I retry with 6.1.12

Yup! Fixed!

Deleting everything and re-building the virtual machine with 6.1.12 and the PIWIS simulator is running great on my MacBook Pro. Thanks @chsu74, I spent about an hour yesterday trying to debug the crash, didn't even occur to me that it was a VirtualBox version issue as I had never previously had it running properly...

Nuttyprofessor - I cannot agree with you on this one. The PDK is serviceable as proven by many posts but Porsche refuses to permit this in their dealerships. Imagine if every dealership took this approach. There are consumer laws against this practice in many states and in my estimation Porsche is close to an Attorney General lawsuit for consumer protection violations. Therefore, in the meantime, the little guy is forced to otherwise work around the problem with solutions like this. Every car owner has the right to work on their car and the dealerships cannot elect to deny this. If they were allowed - they wouldn't sell repair parts bit lawsiuts and consumer protection laws have forced the issue.

so today my PIWIS arrived. I can confirm after testing and activating Cruise Control the software and PIWIS hardware can indeed code Cruise Control on a 9PA

well happy and in total my CC install cost me
less than £50!

Also curious if you can code/activate backup camera lines when using an aftermarket solution? My CD came without a backup camera from the factory. Added a aftermarket camera and it runs without lines. Believe the backup lines is a software driven application with steering angle input etc...

That's awesome. I'm glad to see the steps worked out for you.

I highly recommend setting some time aside, even in sim mode, to play around and discover all the PIWIS functionality. It's a bit clunky to navigate but once you start figuring out where everything is it all falls into place and becomes much easier.

markmark26

did you or your indy buy it from them ?

chsu74

Indy has factory PIWIS and PIWIS II. Bought the Chinese PIWIS III the other week but not direct for post sale support etc. and paid roughly double the price.

So although my Cayenne is fine with VAG-COM, it is apparent that for my 997 I will need a PIWIS clone. After reading many threads, it seems there are two ways to go:

1) Piwis 2 with a Samtec HSX clone, which is relatively expensive (if it doesn’t work and goes in the garbage) or

2) Piwis 3 with a modified VAS6154 interface, which is much cheaper but seems more sketchy and untested.

Any opinions or which of these two ways to jump? Thanks.

PV997

I disagree with your first comment and will throw in my two cents. The PIWIS2 Samtec clone is only around $430 shipped and as far as I know none of us have had any problems. The only one I know of that did fail was from the threadstarter over on Planet 9 and his was immediately replaced by the vendor free of charge. The PIWIS 2 is fine up through 2018 model year and there is no benefit of having a PIWIS 3 for a 997 except perhaps a more modern interface and a bit faster. There's a good review of the PIWIS 3 from a PIWIS 2 owner here:

https://rennlist.com/forums/panamera...piwis-iii.html

Currently the PIWIS 3 costs twice that of the PIWIS 2 so I don't see why it makes sense to spend the extra money (unless you have a new Porsche in your plans or can't live with the PIWIS 2 interface). The PIWIS 3 has come down in price over the last year so hopefully it will be more competitive soon. It isn't now.
