Project Cars 2
This tutorial explains how to enable the UDP Telemetry in Project Cars 2 and is intended for Playstation 4 and XBOX users (make sure to update the game at least to version 2.0!). Basically this can be also used on the PC, but I advise to use the Shared Memory Interface on the PC.
Open the options
To enable UDP Telemetry in Project Cars 2, open the options of the game. Then click on "System" (Configurate External Apps)
Enable UDP Telemetry
Select a UDP-Frequency (1 is the fastetst setting), e.g. select 1. If you experience connection problems or delays you can increase the UDP frequency
Then select the entry "Project CARS 2" or "Project CARS 1" for the UDP Protocolversion option. The app supports both protocol versions.
If you still get no data after configuring everything according to the instructions above, you should try to switch the connection method of your PS4/XBox One. If you are currently using a LAN Cable to connect the Console, try to connect it via WiFi or vice versa. Sometimes the game sends the data on the wrong interface.
