CV 116
Engine Exhaust Control
Description
This CV specifies the Auto-Exhaust Synchronization Rate.
Bits 0-7: EX0:EX7, Auto Exhaust Rate
Controls the chuff rate of the steam exhaust.
0 = Slowest Chuff Rate
:
255 = Fastest Chuff Rate
For Auto-Exhaust synchronization, the chuff rate will be generated in
proportion the throttle setting. The CV is loaded with any value between 0
and 255. Higher values will yield higher chuff rates for a given throttle setting.
A value of 0 will disable the exhaust sound.
The correct synchronization rate may be computed as:
CV Value = 115.9 X SPD÷DIA
Where SPD is the locomotive’s speed in scale miles-per-hour at maximum
throttle and DIA is the locomotive’s driver wheel diameter in scale inches. For
geared engines, the CV value should also be multiplied by the locomotive’s
gear ratio.
Default Value: 80
