The forward trim allows an adjustment to the overall forward speed
for consist matching, etc. The value is scalar in nature, that is, it is
multiplied by the desired output speed. The output speed is
determined as follows:
CV66
128 x (output speed)
A value less than 128 scales down, a value greater the 128 scales up.
So, if CV66=16 than the speed will be multiplied by 0.125 for a 12.5%
reduction. Likewise, if CV66=160 then the speed will be multiplied
by 1.25 for a 125% increase. A value of 0 disables CV66 computation.
CV66 is used on the 3 point as well as the speed table for speed
computations.
