Hi Fahim,

1) Are you sure that you have disabled ASR? Because that is the system 
that automatically controls throttle and decreases it in order to keep 
wheels adherence. Check your keys definition to find out how to work 
with it.
2) Probably the same as for 1)?
3) Well, this depends on how you pass from the asphalt to the 
ground/grass, and at what speed you do so... check out

as an example.

Cheers,
