Dear Devs, according to the developer of Sim Dashboard, rF2 doesn't provide water and oil temperatures from most of the cars. Thank you for your help in advance. Quote from their letter: " Hello, that is a bug of the game. Certain cars do not provide the water and oiltemp and always return zero. Not sure if this intended or a bug, but only the game developer can fix it. Best regards Christian Web: www.stryder-it.de/simdashboard"
Engine telemetry sensor isn't enabled, probably in most/all DLC. It's not really a bug, but hopefully something they improve at some point.
If I may add to this... the delta, sector and car ahead/behind times seem to be a hit or miss. Even within the same car category and track. I have tried only S397 content and it still sometimes it works and sometimes not.
