Patch to 1.40 Rev. B by kenworth_john
Version 3.5.1 with Cat C-16 by kenworth_john

Changes in 3.5.2:
– minor fixes, descriptions in truck manager, some sounds, typographical error ‘disel’ on dashboard
– added air gear sound (only for better atmosphere when driving)
– added very minor traffic influence, for more real life behavior of ai traffic
Traffic mods will overwrite this file. You can delete or rename traffic.sii in \def for ‘no influence’.
The number of cars has to be changed in ATS ‘config.cfg’ (uset g_traffic 2.5 or 3 for example)
– added Detroit DD16 engine with real life specs, took great sound of dd60. The sound is nearly the same in real life.
– added N14 tuned with real life specs, took great sound of original N14
– added M11 reworked with real life specs
– updated transmission files, engine brake, retarder, shift time
– added some transmissions, especially the Eaton Ultrashift 13+1 speeds. Real life specs from Eaton.

The hand crafted torque curves change the original sound of the engines.
There is no real need to make new sound banks.

Pro tip: Choose the Eaton 13-speed retarder 3.55 ratio transmission. try ‘shifting’ and ‘automatic’.
Shifting mostly makes better sound, due to reduced rpm of the engine.
Turn up the volume of your sound system for best experience.

–Transmission and engine mods will not work on this mod. tried to fix, but it was not possible.–
