Yes, this track is frustrating and finding a setup is a headache! Somehow I won the Formula Gran Turismo Championship by skipping the Monte Carlo event, but I'd love to get this track down. My B-Spec driver took 3rd and lost by less then 1 second... just couldn't get him by the 2 drivers in front. Ready to tackle this track again but I see myself getting pissed off again! GOOD LUCK! I will let you know if I find a proper tune.
Im not a tuner, so if it doesn't work for you i apologise. It was made for people who normally use no assists at all.
I did a 1.14.7 with it. I know that's not great, but the problem is the ultra short 1st and 2nd gears which pretty much become useless. Should be better for traction control users though. Truth is i think whatever setup you use this car is a handful
