I have one of the K-Line/Lionel sd70 engines. it runs fine with the exception that it's response on the Cab 1 and legacy controllers are different. On the Cab 1 it takes a few turns to get it running to a medium speed. On the Legacy I need to get it up nearly to the end of the graph to get it going and then dial it back. I have numerous other engines and non of those exhibit this behavior.
Any suggestions?
