Ok. I have noticed that Fuel management for 50% race is terribly optimized. Starting the race with 1.5 laps off extra fuel in the tank and driving at standard i noticed that i am actually saving the fuel, and by the 8th lap i have 4,15 laps of extra fuel in the car.I was able to run at rich settings for the rest of the race and still head fuel left in the tank. That is ridicules. there is no need to run lean settings at ALL.... I think that the game is not recognizing and applying (scaling down) the changes for the 50% race length correctly. I have found the way to correct this by reducing the fuel tank of the car by 50% and now fuel consumption is great and realistic. Moding the game is not the best way to fix this but rather it needs to be fixed by Codies.
