Made some good progress in Porsche Track Precision Gateway reverse engineering, was able to read all important channels.
PTPA gateway is a hardware module I bought on the second-hand market 5 years ago for $50, officially that option costs ~$1000+ , wired it directly to the vehicle into the MMI CAN segment, as factory does that.
Unfortunately, PTPA app lap timer does not support non-GT vehicles, so can't really use it with my Cayman 981 S, probably can do emulator and put there GT4 VIN, but don't have time and will for it :-)
