Does anyone know if the LGB MFX equipped locomotives have a CV programming lock? The reason I want to know is I have an LGB MFX locomotive that is factory equiped with a Massoth Round Boiler pulsed smoke unit. I want to change some settings in the pulsed smoke unit and don't want to comunicate with the MFX decoder.

I don't think they have. Also I think the pulsed smoke unit is connected to the motor decoder directly possibly using SUSI. I am not 100% sure on this as I have had three LGB locos with factory fitted sound and pulsed smoke (Saxon 1K, Saxon VIK and Rugen 0-6-0 with tender) and in all cases I never found an option to program the pulsed smoke generator independently, or had the nerve to take them apart. If I changed the loco motor address the smoke generator still worked on the new address which is why I think it may not have its own independent decoder. Sorry not to be definitive. Which loco do you have?

EDIT: you might want to look at this thread which is related:

LGB 20184 "Franzburg". It has the newer Massoth Round Boiler smoke unit which has it's own built in decoder which does have a programming lock. There really is no problem with it but I would like to adjust the pulsed smoke to puff once every wheel rotation. Currently it puffs twice, once for every 1/2 rotation which is probably prototypical for this locomotive. If you run it any more than a crawl, the smoke puffs become so rapid, it sends more of a steady stream of smoke rather then the puffing effect. Not really a problem but that is the beauty of DCC. If you don't like something, change it to what you prefer.

Hi - I've repaired a customer's LGB 26844 Meyer Mallet Steam Locomotive with mfx/dcc and pulsed smoker. I had to order through Marklin USA to Marklin Germany a replacement sound board. After I installed the new board I discovered the smoke unit was also defective but I couldn't get a new Massoth pulsed smoker to work.......it has a different wiring configuration than regular Massoth smokers, e.g., 3-wire Susi instead of 4-wire Susi. So I then had to order a replacement Massoth smoker from Marklin.

I also think the CV configuration is different on the Marklin-used Massoth smokers than the regular Massoth pulsed smokers. On the Marklin-used smokers for their LGB diesel locomotives, the CVs are 800 - 900 series. So, I'd suggest you contact Marklin Germany Customer Service to get assistance on the process for changing the CV settings on the smoker.

Tom, I read your post thanks to Dave M. Excellent information. Thank you for taking the time to update your posting and also reaching out to me on this post. I also want to thank Dave M. for being so quick to answer. It's people like yourselves that help keep the Hobby and this Forum alive. I have decided to leave the settings alone for know. Thanks again.
