Thanks for your hard work Adrenaline. I just have a question for you. Tunes are often designed for different tyres and pp restrictions than we are confronted with here. Can you give me a rule of thumb for how to adjust the LSD to suit harder tyres? I guess the suspension and transmission will be roughly the same regardless of pp levels or tyre choice, but things concerning grip, like the LSD, have to be tweaked I guess. A bit of advice would let amateurs like me use a tune like Praiano's which is made for higher pp and racing softs.
Thanks in advance.
Um, a general rule of thumb.
The softer the tire, the stiffer the springs.
Thus, in reverse, if the tune is designed around Racing Softs, and you're going to downgrade tires, you should soften the springs up by a percentage. The actual percentage is not a known factor. If I had to ballpark, I'd say 5-10% per tire grade?
As for the LSD...
I'd say it's far easier to just create your own for the specific tire grade based on stability and outside/inside tire spin.
If your outside tire spins, lower the LSD Accel.
If the inside tire spins, Raise it.
The general rule of thumb, is I lower the LSD Accel setting 1-2 per tire grade.
Initial and DeAccel are a bit trickier and usually more effective in testing/driving. If you need more stability in general, raise the Initial. If you need more rotation (at the
potential sacrifice of acceleration and 'forward grip') lower the initial.
If you need more stability under braking/corner entry, raise the LSD Braking sensitivity. I recommend trying to get as close to 5 as possible most of the time though.
* I say potential, because this is not a widely agreed upon standpoint within the tuning community, but it is my personal opinion.
Hope this helps.
Edit:
Just checked Praiano's settings, I'd jump down to a 9/14/9 to begin with.
Then adjust based on what I've described above. I'd avoid the positive rear toe, raise the front ride height for the bumpy track, and 11.6/11.2 on the springs and then go from there. Ride height 5/5 and look for bottoming out on the tire load indicators.
Edit 2:
Just noticed the rear Downforce. Due to the updated physics and their relation to aerodynamics, I'd lower this until the car developed oversteer. I might take the car for a spin today.
