Hi, Well, it's more an impressiñon than an certitude, but I've "observed" that using a setup that works great (newly modified and stored whith a new name) , exiting the race and re-entering, the same setup behaviour is very different. I noticed this some times in last months. ¿Is it possible that some randomness is affecting car behaviour? Maybe some memory corruption, or not storing the correctly the setup. I repeat.... It's an impression, but I noticed this behaviour so often.... While racing (without exiting) the car behaves in a constant way with the "new" setup. After exitin an re-entering, it's very different... Anyone with the same behaviour??? Raftor
