ponents of the vehicle that required
changes to the chemistry of the ve- hicles to keep all the systems hap- py. Especially important to shops building race cars out of street cars where much of the equipment was deleted or changed. The PIWIS 2 served us very well for a long time. Unfortunately, that changed in 2016/2017/2018 depending on the model year when the next up- grade was required.
Note: A last minute update on the PIWIS2 that occurred on the 1st of January after I wrote most of this article. We do assume there was possibly obsolescence planned in the computer, but as of the 1st of January 2021, the PI- WIS 2 support for the 986/996/92a Cayenne, etc ceased to work. The later cars for which it was working before still seem to work, but have died for earlier support, which is odd. The only work around to this issue we have found is to back- date the computer’s date to before 2021, then it will work as it did be- fore.

The PIWIS 2 Menus
With the newer models rolling out around 2016/2017, and the cars had become very involved electronically, the next generation PIWIS 3 was introduced. This computer handles all previous models all the way to the current models coming off the line and can be updated as new generations roll out. This includes not only the street cars, but also the factory
special coding for it to work. You PIC could swap steering wheels, install fixed wing spoilers, aftermarket suspensions, etc. But to keep the car from throwing fault codes or lights on the dash, sometimes the control modules for these com- ponents had to be coded specially with the PIWIS 2. Using a back- door engineering mode, the repair shop could also make significant
