Hi there,
Reliving this thread because passed a year and I got no workaround.
I've watched some replays of my races with essentials app running to see what AI is doing and ... bullseye, once they stop at pit stall they got their tank fully refueled instantly, like a programmatic stuff.
So their pit lasts only the time to change tires.
It's really mesmerizing, because there is no info in the net.
Recently I was looking for variables from AI to see if there was something there missing, but can't come close to an end in this matter.
It's really frustrating because, last year I've raced a 70's WSC endurance in half distance and really struggled in more twisting circuits to have a pace fast enough to overcome the pit deficit. I've "cheated" by reducing the time to refuel my car as Stereo has proposed to help, and thus could do some decent races, but others was a complete disaster, making such a big and waited project a bit of a disappointment.
And I'm not addressing the problems with damaged (crashed) cars that come back to track running in such slow speeds with suspension problems that spoil the race causing traffic jamming and more crashes.... And the AI lines, track boundaries... the list goes on.
If someone could find a solution for this refuel time problem or how to get this instantaneous refuel disabled making the game to refuel in the proper time, please let us know.
For me, I'll keep trying to find a solution as I really do almost only offline races.
... who knows in the coming year, with this fixed and more knowledge to overcome the game limitations, track and AI problems I redo my 70's project in a more proper manner.
