I saw a posting from Dan Pierce I believe some time ago about the older versions of LGB Buhler motors requiring a special CV setting to make them operate better with a DCC decoder, but I can't find it. I just completed a DCC sound conversion on a customer's LGB 2174D using a Massoth XLS sound decoder. It has the older version of the Buhler motors but it was operating fine in DC analog power. I tested the locomotive after the installation and get some very slight jerky movement at the lower speed steps. I tried various adjustments to CV2 starting voltage but that didn't help. So, I turned off the CV49's digital control and left it to just CV49=1 since the customer still uses the old LGB MTS system and 14 Speed Steps. As I've experienced before, and other hobbyists have also encountered, turning off Digital Load Control makes the the motor run smooth as silk but then increases speed too much between Step 1 and 2 etc. So I tried all types of combination settings using CV2, 5 and 6, but still can't reduce the high speed increase between Step 1 and 2, etc. Yes, I know that using Speed Steps 14 instead of 28 is part of this, but I've set a lot of decoders for 14 Speed Steps and there's not such a large increase in speed between 1 and 2 as this motor is doing. Is there another CV setting I should be also using for these older Buhler motor to make them operate well particularly in Digital Load Control is ON or OFF. The customer is retired and on a tight budget so I don't want to replace the older Buhler with a new motor. Thanks!
