I would like to know how anyone tune Pagani Zonda C12S. It could be from recent 11th tuning competition or past experience.
Here's mine:
Fully tuned, at Autumn ring Zonda C12S shows some very bad understeer nature. At mid corner it will tend to go wide, every push or lift off throttle make it turn even wider. You can't get fast in corner at all. What make it worse, it has so much power. It will send the rear to swing around if you don't do some throttle control. Without some TCS, I don't think I will be able to tune this car properly. Very understeer car that will send you to spin if you don't control your throttle.
The first thing I did was reducing the acceleration. I do this by fitting stock flywheel and using 5.500 final drive. And of course, TCS=1. The car became more tame now. Slower, but I can control it better, besides, I still leave the stage 3 NA mods in place, still powerfull
.
Next was to cure the understeer. I start tuning with softest possible suspension and then make stabilizer balance toward the rear. After some turn I realize that this car need plenty of that, so 1/7 for stabilizer. Since many car mid corner behaviour can be improved easily with stabilizer, I really wish PD provide the stabilizer range between 1 to 10. The car behaviour on mid corner is slight understeer now.
Next I tried to see how it handle when I push or lift off throttle during cornering. It still go wide. To cure this, I make the damper balance toward the front. After some trying I found 10/7 10/7 damper would be good for me. At this value, the car would not be tail sliding when lift off or go wide when push throttle during cornering.
Next, I tried to find what is the lowest ride height possible for this car in Autumn ring. When using minimum ride height the car suddenly feel unstable on many turns, loose grip often. At medium height, the car feels ok, but at last corner the car rear will slowly drift to the outside, something that is not happen when using maximum ride height. So I raise the height to the final 80/80.
Next, brake, since I don't know much about braking I use my safe braking value 4/1.
In the end, this tuning satisfy me with better mid corner handling and no surprise corner entry. The car still has problem though. It will loose front traction easily, understeer on limit, hard to recover from sliding and still rough transition from low speed oversteer and highspeed understeer.
How about yours?
