The fuel vs Virtual Energy concept takes some getting used to in LMU - particularly for cars like the GT3s that aren't hybrid and only have petrol to worry about!
Briefly - WEC no longer BOP cars using fuel-flow rates, restrictors etc. (well, not for GT3s in this context anyway) and use the notion of Virtual Energy instead (measured by a torque sensor on the rear axle - it gets around the whole issue of completely different engines by just measuring the amount of energy dumped on the rear axle).
Anyway - a couple of key points:
i) If you run out of VE (but still have some petrol left), you will get a SG (Stop/Go) of 100 seconds! That's a whole lap at Bahrain Outer... Note that if you run out of VE entering the pits and coast to your box - you're still going to get the SG.
ii) If you run out of petrol (but still have some VE), your race is over.
iii) Notwithstanding the above, you can use the Fuel Ratio setting to adjust how much physical fuel is put into the tank when you ask for 100% VE. The 'ideal' (for me) is to find a ratio such that the estimated number of laps for VE is equal to (or slightly less) than the estimated number of laps for the physical fuel...
The HUD overlay gives a readout of the current state of physical fuel (litres left in tank and estimated laps) and the VE (%ge left - and estimated laps).
For the Mustang, the ideal Fuel Ratio is about 0.83, 0.82 for the McLaren.
Increasing this number increases the physical amount of fuel added to the tank - too much and you are just carrying dead weight. Too little and you may have to pit early (while VE and physical fuel > zero) or run out of fuel, ending your race.
Reducing the figure might result in you running out of physical fuel before VE.
Other GT3s might vary (remember, this is part of the BOP) and your actual fuel/VE usage might vary from the estimates (short-shifting, lift'n'coast vs shifting at the red-line).
The suggestion is that you set the fuel ratio to around 0.83, set Virtual Energy to 100% in your car setup screens and then hit the track. If the estimated laps from fuel is a little higher than that for VE, I'd say you're good to go. These figures are in the bottom-right display of the HUD. Physical fuel is the pinkish bar with a fuel-pump symbol, VR is marked 'NRG' (EnErGy!)
(Fuel ratio can be changed under the Powertrain section of setup).
