From your log I see that you are using teltonika codec 8, for OBD Data you need codec 8 Extended.
In the teltonika configurator:
Systems menu set Data Protocol to Codec 8 extended .
OBDII menu set priority to at least LOW in order to receive data on your server.
And then depending on your vehicle, the data will deffer.
I am testing FMB001 on Skoda Superb and not getting fuel data io48, io60, but getting RPM, Engine Load %, and other useless data etc.
How can i understand what "io" value means something? I can see some io values in "More details" of device but how can i manage them?
You have to ask Teltonika for the IO mapping for your specific device.
Nothing other than breakdown. Let me know if you find the issue.
