It a piwis 2 , I tried the date change etc , after putting it into programming mode it now says cannot determin mode , it won’t even let me into the settings to change back to v mode , this only happens on cayenne pre MY 2010 ?

 

Change it manually on the user.properties file.in the pidt_mig folder.

If currently setting is in EEngineering), change in properties to 4, i believe.(see the list)

 

Any chance of step by step on this as not clued up on file altering ?

 

Had a search through hd and can’t find a folder called pidt_mig ?

 

There it is.

 

Great work , found it and opened the file , seems it’s already in mode 4 ?

 

If the setting on system/... Other model is in E mode, change the user.properties to mode 1, you have to have development.sig file in workspace folder.

 

Thanks for the information on the PIWIS 111 My 971 diesel has been caught up in the panic by Porsche. So they have removed my option to deactivate the auto stop/start on the screen in a recall campaign. The company vxdas have updated the software and i just wondered if the 4.0 will have the same options to turn off the auto stop/start?

 

perfect found that and edited the file and all working now , thanks guys for all the help

 

Migrate to piwis 3 is better.
Looked like it works on Win 11

 

the Vmware image will be deployed on any system that can work with VMware Pro 16 and newer
the Piwis image only works on windows 8 and on windows 10 (versions 39.5 and 40)

 

I assume this will require a different hardware than the piwis 2 ?

 

I have PIWIS 3 from a chinese seller, I am specifically looking to run engine hours, mileage and overrev checks on Porsche. I can do this on 997 Gen 2 and earlier Porsche without issue - by loading diagnostics in Piwis 3 and looking up the actual values under DME. How do I access the overrev data on 991 and 981 models? Can anyone explain the procedure to find these - as I can't see these items under DME in diagnostics? I have another system called Autologic which can find these overrev data points on the 991 and 981 cars.

Thanks!

 

Good coding people of the forum.
I'm trying to shut off the cold start sequence. I found the entry on DME, but it doesn't allow me to change it. The first entry (bitfield_cold_start_system) allows you to choose active/not active. I cannot have that entry by itself, even if I only select it, by the coding screen. It always come with the below entry (bitfield reserved) which has 0 for value and no option to change it. When I change the first one to not active, I get a message that the values on the second one are not accepted.

What am I missing here? Anyone had any luck with that particular subject? Could it be inaccessible because of pollution laws?

The other potential useful entry is warm up request deactivation. That one I could not get to work as well (second pic).

 

May I ask why you want to disable the cold start ? Isn't this necessary to warm up the Catsquickly ?, etc ?
thx
