Engine brake effect

Known from LS15 of twizzle, I've only converted him for LS17. Urmodder slin2R

Reminder or who does not know the mod:

The standard engine brake is at a higher speed, also depending on the weight,

So reduced, that a "roll out" can affect the game more real.

Standard set the tractor almost an emergency full brake out when you release the accelerator pedal.

This script solves this phenomenon.

Have fun with it
