Trim Adjust is the feature incorporated into the decoder by CVs 66 and 95.

These Configuration Variables are Optional, so your decoder may not include them.

Forward Trim

Forward Trim specifies a scaling factor to be applied to the calculation of the motor drive voltage when the locomotive is operated in forward. It is interpreted as n/128. Setting CV 66 to Zero disables the feature

Reverse Trim

Reverse Trim specifies a scaling factor to be applied to the calculation of the motor drive voltage when the locomotive is operated in reverse. It is interpreted as n/128. Setting CV 95 to Zero disables the feature
