just uploaded a patch which roughly emulates 2010 running on full fuel still needs some work as you still get and extra 2 laps of fuel at pit stop, also reduced pit stop time, at the moment the patch only works if the magic data is set to a one stop race
and all the cars are forced to start with the full load of fuel i have set the magic data to a one stopper but when one of the ai cars have a stop after a lap or so (broken Wing ) The fuel load is set to a one stopper again so there are much faster than the rest
