PIWIS 3

[PhillyTCT4S]

Hi,
I recently received a Piwis3,4 system and was wondering if anyone knows about manuals, procedures that will describe the working process and coding options.

I saw several on YouTube but nothing concrete.

Any help would be appreciated.

Thanks.

I would like to know too… would be nice to see some documentation, but knowing Porsche changes are slim

Not sure what you mean by PIWIS 3,4.

If you screenshot which version you have that would be a help.

PIWIS 3 has been available for some time.

PIWIS 4 is a different version, it may operate under similar menus, but not seen that version in the wild

Sorry for the confusion. I have both but need piwis 3. I coded some options myself but I am sure there is much more that I can do. Was wondering what other people used it for on their taycans.

What have you been able to code so far?

 

[PhillyTCT4S]

Its a learning process but so far amount of flashes for the turn signal, flashes and beeps for the alarm.
Trying to figure out how to code back turn signals from us to Euro as I installed the yellow ones.

If you post up the steps you used, I will see if I can go to the same area and tell you what the UK settings look like

Thanks for the offer. I know what needs to be changed I just dont know where in the BCM2 that option is located. Need to spend more time playing with it. I will post the results here.

If you figure out options like 3D surround or rear cross traffic alerts, I’d love to get the info on that. I’m gonna try myself as well, but this is my first time doing something like this

If you tell us whether you are in engineering mode or in standard and what menu selections you made, we can all have a go in the same area.

Here is the start screen showing the version is 40.9, this version also has engineering version 38.5 that accessed from the menu system, it does more, but it is mostly in German.

ZFAS AU516 003 -> Kodierwert -> Bitfield (5) TV_3D_Presentation

Rear Cross traffic alert (did this on my Cayenne and Taycan). Although, I can't remember exactly what the rear radar ECUs are called on the Taycan. But the configurable options are the same.


Rear Radar S1 (Lane Assist Right) Kodierwert: Bitfield Rear_Cross_Traffic_Alert : with_RCTA
Rear Radar S2 (Lane Assist Left) Kodierwert: Bitfield Rear_Cross_Traffic_Alert : with_RCTA
ZFAS (Assist) Kodierwert: Bitfield (3) FW_RCTA : installed
PSM (ESP) Kodierwert: Byte 12 Rear Cross Traffic Alert : ja / an

What a rip Porsche would charge $$$ to only include this with Innodrive.

 

[PhillyTCT4S]

Thanks for the info guys. Yes I have engineering mode enabled and I am on 42.4000.037 version

 

[PhillyTCT4S]

I will try the above options too.

Just took a quick look but in simulation screen and was able to find Radar S2 cross traffic alert.
Quick question if it is disabled in my car right now and I will code it as with_RCTA will this work or do I need any additional hardware for it to function? I have Innodrive.

RCTA uses the LCA sensors. So if you have those, RTCA should work.

There's a graphic somewhere on this thread that depicts all the sensors/radars on the car and what Drive Assistance Systems come with which sensors. Since you have ACC, you also have the LCA sensors.
