Thanks, much appreciated. Question: why didn't you use the minimum weight? Is it for cornering stability, since you put the weight at the back? Even if I feel it's more stable like that, I'm faster with minimum weight.
I have a problem though, and this extends to all tuning by PD: I hate the fact that when you tune the engine you can't remove something, even if you change setup file.
The problem is that in my Cayman I have high lift cam shaft so I can't have the same setup as you.
ECU and power limiter sliders are different to reach maximum horsepower. To get to the maximum of 300cv (295hp), I had to use a sport air filter, racing exhaust manifolds, put ECU at 85 and power limiter at 70 (all the other parts are like in your setup).
I also can't have the same transmission tuning as you. Values for final and 1 to 6th gears are messed up since I have 8624 rpm with that cam shaft and you have 8296 rpm without. Since I don't know how to tune the transmission by myself, I tried to replicate what you have (you can check the attachment). But because of the different rpm I don't know if what I did is right to bring maximum power for each gear.
My best lap with the setup adjusted this way is 1:52.702. I think I could do a lot better with what you have.
I'd have to buy another Cayman, or another engine, but this is plain stupid design by PD. They're too fixated with "realism". In Forza Motorsport it's all very simple: all you add, you can remove.
