Please give us the option to adjust the pit strategies in the menu, before starting the race. It is quite stressfull to fiddle around with these things while racing.
The only workaround right now is to set everything up in the incar menu on track during practice, these settings will be remembered for race.
The Pit system as it is right now doesn't work for me at all. I tried to setup a Pit stop once during a race with the d-pad on my Thrustmaster wheel but even with the d-pad it wasn't possible. Now I use a aftermarket wheel from SMR and that doesn't even have a d-pad. There are 10 buttons and that's it. No way to navigate that menu at all. if we want to do Endurance racing I think it is crucial to be able to setup the pit strategy (gas only, tires only and so on) in a somewhat easy way before the race. At the same time I'm pretty sure Reiza will come up with a solution.
Here is a vid showing the pit strategy system from pcars2 which AMS2 adopts some aspects of. A bit more UI work and we could have this or better.
The AI seem to be able to do their pit stop extremely quickly, not sure what is actually done to their car, but it seems a bit suspect.
