Hold on, I forgot how to do this..
I just tuned this for the midship professional challenge.
No aids besides weak ABS.
Manual Transmission.
It's all straight forward, except transmission which is a flip, meaning in this EXACT order do these steps.
Default the transmission.
Select full customizable.
Make top speed clicker max speed.
Make final gear 5.000.
Make top speed clicker minimum speed.
Set gears 1-7 to corresponding numbers.
Finally set final gear to 3.400.
As a side note, if you're coming up on some grass the E-brake is your friend with the Veneno. And also running manual and downshifting definitely helps it slow down.
