I have been thinking about a new fuel system to help out with making a complete strategy before the race and avoiding changing it most of the time during a race. This is how it works:
You have an n lap race.
If you pit between laps a and b, add x% fuel in or fill tank to x% fuel (you should have an option between the two). If you pit between laps c and d add x% fuel in etc, until you get the second variable (b, d, f...) to be equal to the total number of laps. This way you can know that if you pit between laps a and b you have to still make a certain number of pitstops to finish the race and it is best to put fuel such that you get to a certain lap... You get the idea. While it may seem like a lot of work to do this between each race, this is not a feature for the casual "weekend" racer, but for a league racer to make sure that he can focus on his driving as much as possible during the race.
