Porsche Piwis III Developer Mode:
The Developer Mode in Porsche Piwis 3 is not available when you update the shell, coz you lose the menu diagnostics configuration to switch between regular and developer mode,
Problem solved if you copy the old file com.porsche.piwis.Shell.exe.config
Here is how to update the shell config. and get the diagnostic configuration boxes back, on the system tab.
After a successful update from 37.250.20 you will loose the two above mentioned boxes from the System tab.
If you did not loose them, then the [PIDT] diagnostic software did not update completely.
So it’s a good thing to loose it !
Go to C:\PiwisApps\Shel\ and carefuly edit with notepad this file –> com.porsche.piwis.Shell.exe.config
after the update the PIDT section shows up in green, after U edit it it will be blue.
First picture shows, red underlined, 2 places, beginning and the end of the green section, what to remove.
On top [Line 568 on mine] U delete these four symbols !–< on the bottom [line 603 on mine] U delete these 3 symbols –>
Then U save the config file.
Restart the PC and your Diagnostic config box for 991,981,970 and Diagnostic config for other models RE-APPEAR.

It’s how to enable Developer Mode for Piwis 3
Developer mode is a special Piwis program that allow a lot of advanced coding normally reserved only to Factory.
With this function you will have a tool that can do more than software of official Porsche Dealer.
For example, you can reprogram all ECUs completely offline.
How to use Piwis Developer Mode:
Install winrar and winhex on your computer.
-1-locate the file c:\program files\porsche\PIDT_P_MIG_DLSS3\pidt\plugins\de.dsa.pidt.datatype.jar and copy it on your desktop in order to modify it.
Open it with winrar,in the wirar windows locate the file
\de\dsa\pidt\datatypes\utils\Helper$1.class and drag it on your destop , delete it from the archive after the copy, keep the winrar window open.
Open Helper$1.class on your desktop with winhex and goto offset E81, replace 9A by A7 and save.
Drag back the save file on the winrar windows still open and click OK.Close winrar
Copy the new file de.dsa.pidt.datatype.jar you just made in
c:\program files\porsche\PIDT_P_MIG_DLSS3\pidt\plugins, overwrite it.
copy the file aftersales.sig on your desktop and rename it development.sig.Copy this file back in the folder
Do exactly the same method given above with the folder c:\program files\porsche\PIDT_P_MIG_DLSS3 with its own files.
To transfom it in developer :
981-991, mode, operating mode, E= development, P= production, V= aftersales ( regular piwis)
Other models line, mode, operating mode, E= development, P= production, V= aftersales ( regular piwis)
This method to switch between regular and developer works only with my backup and will not work anymore after
Maybe this helps Folks some.
