You can just download the tool, set it up, i.e. have a working Telemetry Tool setup.Thank you, but I'm still wondering if I can only be a racing engineer (I don't want to drive) I also tried https://www.team-telemetry.de/download but we also don't know how to set it up.
And we don't connect online, only a friend plays a single career
E.g. if your friend runs F1 22, then he forwards the UDP data (in Tool: Settings -> Network Settings --> UDP Forward) to your IP address, where you run the Telemetry Tool.
You can make this easier by running a VPN tunnel between your locations (e.g. Hamachi is used by many of my users), as then the IP addresses are "local" within the VPN tunnel, so the traffic can easily sent and there is no need for messing with firewall and public IP addresses etc.
Your friend can play single player career (or online), only thing needed is that he runs the Telemetry Tool with the UDP forward enabled with your IP address and that you run the Telemetry Tool. Then you should receive his data.
Cheers.
