CV54: Torque Compensation & Switching Speed In FX3 decoders, CV54 is used to control the decoder's torque compensation and switching speed features.
Torque Compensation improves loco performance by internally adjusting for the loss of torque caused by SuperSonic™ operation.
This feature is turned on at the factory. Switching speed gives you fast access to lower speeds used in switching operations.
This feature effectively reduces the throttle's target speed by about 50% and reduces the effects of acceleration (CV03) and deceleration (CV04) programmed into the decoder by 1/4 when the user activates this mode by turning on F6.
