Hello there is the possibility of displaying the water temperature as well as the engine oil I use the Z1 software on a dashboard and it does not indicate the temperature to me on GT3 and many others from studio 397! on mods it works ... Thanks for coming to my help.
Most of the DLC content has locked telemetry. We have always assumed this was done at the request of the various manufacturers. But tire temps, oil, water etc are just not visible to telemetry. Now the new titles from MG with S397 involvement may have some tie-ins with Michelin, perhaps we'll see more data lockouts in those titles as well. Unfortunate, but I do not know of a work-around.
