Hi Friend,
Please with EP cars dont adjust the Throttle setting with Exponontial or any other features on radios.
with the new generation Speedos have many items that can be controlled via ESC program cards and if you re-manupulate the program with radio.
it may resulted with the failure at your ESC(probably sensor board may come off)
For Sxx v2 stock spec of LRP yes setup 2 helps to acceleration but before that for more traction first play with your car softness. then ESC can do final details
(not neccesary).
on the other hand, if your car oversteer especially at cornering. then you can decrease STEERING exponentials or EPA from RADIO
