If consisting more than 2 locomotives, release the second fastest locomotive from the consist and remove it from the track. You should avoid adjusting the Master from this point, or you may have to redo the other locos to match the change/s you make.All other locomotives to be in the consist will have their settings adjusted to match the Master.Record which locomotive is the slower and this will be the Master. Run the consist at maximum speed with the locomotives separated and see which locomotive is the slowest Select each locomotive in turn to create an on the fly consist Repeat steps 5 to 9 for each locomotive to be speed matched

Release the locomotive from Engine Driver on the phone/tablet Note: Some suggest that 255 is too high a value, as it produces an unrealistic top speed and suggest 180 is a good value to useĪdjust the VMid half way between VStart and VHigh Maximum Voltage (VHigh) & Midpoint Voltage (VMid) Kick Start helps to overcome motor and drivetrain friction (stiction) and can provide a little extra burst of power to get the locomotive started when speed step 1 is selectedĨ.3.1 Kick Start from 1 to 8 (typically 2 to 4)Ĩ.3.2 Total PWM Period/Motor Drive Frequency from 0 to 50 (typically 4 to 25)Ĩ.3.3 Kick Strength/Torque Kick Strength from 0 to 50 (typically 4 to 25)Īdjust the Dither settings to make the locomotive start consistentlyĭither applies extra voltage spikes at early speed steps to assist getting the locomotive moving smoothlyĨ.4.1 Dither Frequency from 1 to 10 (start with 5)Ĩ.4.2 Dither Amplitude from 5 to 50 (start with 25) Kick/Kick Start/Torque Kick Rate (Kick Start)Īdjust the settings to make the locomotive start consistently Used to ensure smooth starting in conjunction with Kick/Kick Start and Dither

Or at least make all the locomotives start at about the same percentage) Adjust the VStart so that the locomotive starts moving at about 4%

Read the following full sheets for the locomotive Select each locomotive to be speed matched Select the locomotive in the Roster Select Program Set DCC++ to Operate Mode In JMRI, Select Programming on Main A. 10.0.0.5:12090)ģ.7 Run each locomotive in forward and reverse for at least 5 minutesīasic Speed Matching Set DCC++ to Program Mode In JMRI, Select Programming Track For each Locomotive It is highly recommended that the current settings on each locomotive are recorded before making any changes so that the decoder can be restored to its previous state should it be necessary. The document is by no means exhaustive as different decoders have different settings that require differing approaches. This document has been produced to assist model train enthusiasts using dcc-enabled locomotives to fine-tune (speed match) their locomotives for consisting purposes.
