2 years using RC and have not been able to get Trans Temp or Dif temp.
I’m almost sure is not possible.
so it’s not just you.

I believe diff temp is on a different CAN...however I did get transmission temperature working (TFT -transmission fluid temperature) with the LUA script that's available; I tweaked the script a bit to only pull IAT (post intercooler), TFT, and Oil pressure, because it polls the extended obd2 parameters. If you want assistance with transmission temp happy to help.
How have you liked RC?! I'll be hitting the track in less than two weeks to test it all out

Watch this. Min 6 or so on the video
yes. I personally LOVE RaceCapture. I designed my own Race dash screen and have been using it on Track weekends and Time trials for over two years.
You can see it on the video in action throwing some engine oil temp warnings (was done on purpose to test the actual warning system)
how if you get that data, OBD connection? Or via the CAN Bus.
I’m interested.

OBD... I'll send you a screenshot and the Lua script I'm using. I tested out the whole setup at the track two weekends ago and I loved it!Watch this. Min 6 or so on the video

Lua script is from another user on here and you can import it directly via race capture...I just edited it.
