Am I correct in thinking that the fuel level reported in the xml for P2 cars is a percentage of a full tank?
If that is the case, I drove around Spa in a 2023 practice session in a P2, and a full tank is 63 litres. Therefore, it seems LMU-RC is calculating based in a different (perhaps an older) full tank capacity.
Sorry if I am mistaken - I hardly ever drive cars other than GT3.
Also, just a little head-up: the map for Laguna Seca has the incorrect sector colours. S1 ends on the straight before Turn 5, and S2 ends between T9 and T10..
Still loving your work!
