Porsche RJ dates the PST2 introduction to 1997 and identifies it as based on the Bosch KTS 500 computer system, using Porsche-specific software. A 2004 Porsche bulletin names the PST2 and PIWIS software CD version 22.0 in a specific service context.
The Porsche-labelled tester and a Bosch-green KTS 500 converted to run Porsche software may look similar but are not the same provenance. An owner’s documented project shows a green KTS 500 running a Porsche DME menu. Treat that as an owner conversion and inspect label, interface, cables and software release when identifying a unit.
