Master List of decoder resets

Do decoder resets on program track only!

The manufacturer ID is for the locomotive decoder you are programming and has nothing to do with what system you are using. The manufacturer id is the value of CV8. Example: CV8=11 means the decoder was made by NCE. To learn more about a configuration variable (CV) and how to change them with an NCE system read this article:

mfg id 101 - Bachmann tsunami
reset select loco to 55, cv 55, value of 55
then rock loco to break contact and reset loco
or try setting cv 8 to value of 8
tsunami can only program short address on program track
to identify a decoder as a Tsunami - function 3 , is short whistle
mfg id 11 - NCE factory reset CV30 to value of 2
cv1= short address, default is 3
cv29= default is 6 which is: short address, factory speed table, 28 steps, dual mode on,
cv19 =0   disables consisting
MFG ID – 151 Loksound (ESU)  
Reset   CV8 = 8
The ESU Loksound V4.0 & Select decoders use a multiplier factor of 0.25 rather than the NMRA standard factor of 0.896 for the values of Acceleration (CV 3) and Deceleration (CV 4) rates. This means that you will need to enter a value nearly 4 times as great (3.6) in the Acceleration and Deceleration CVs to achieve the same rate as in a LokSound V3.5 or almost any other brand of decoder. This can be a problem with the NCE Momentum button, particularly if you have V4.0 (or Select) and other model decoders in the same consist.
mfg id 127 Lenz
Atlas / Lenz reset:   set CV8 to a value of 33     

Some Lenz decoders may work with a value of 8 or 33 in CV8. Older decoders used a value of 33. Tilt loco for 7 seconds to reset decoder after changing CV,
mfg 113 QSI
qsi   - sometimes have background noise
qsi cv 23 and 24 to 0   to disable momentum
QSI locos might have a reed switch and magnet wand to turn on.
Generally requires Programming Track Booster
To use ops mode programming / POM must disable voice read back
Set CV62=0 to turn off
The Broadway, Atlas, and Lifelike equipped with QSI (ID 113) DCC sound engines use a different reset procedure. Check the manual that came with the engine. Some use a magnetic “wand” for the reset. If there is no "wand" then open the engine or access hatch and find the reset jumper. Remove the jumper and restore the track power. There will be an audible acknowledgment from the engine at the end of the reset sequence (usually 3 toots of the whistle/horn). Replace the jumper and test out using address 3. If a "wand" is present, locate the internal reset reed switch and place the "wand" over it for a moment. When track power is restored the engine will go through its reset procedure and let you know when done. To find the internal reset (reed) switch, place the engine on active track. Slowly move the "wand" over the top of the engine or tender until the engine alerts you, audibly responds, by a message.

QSI also has a software reset using the following multi step procedure:
(1) Place engine on main track if it is still responding to its address. If not responding you may need to use the program track.
(2) Set CV49 to 128
(3) Set CV50 to 255
(4) Set CV56 to 113 As engine resets you will hear the 3 toots.
Test out the locomotive using address 3.
QSI also has some selective resets.

To reset MTH to the address to factory default 3.Set the engine on the main, enter up loco #55, to into
program on main. program loco 55, CV 55 with a value of 55.
exit out, tilt loco
and call up loco 3,
perform start up by press F3 to start loco.
If you want to re enable long addressing
at this point, go back into programming for loco 3,
at CV29 enter a value of 38.
Now you can program a long address
F7 to cycle thru 9 volume levels
F8 for smoke
