Hello.
I will check that the Fuel % is working correctly, before next version is released.
Have you checked in the Data window in SimDash (Menu View->Data) if the correct data is received from IRacing?
In the video I can only see when you set the Fuel % the first time, and it seems you are doing correctly. Later on I can't see what changes you are doing because the camera is not pointed to the right place.
Thank you
Cristiano
