Keith,
The Speed control from the DCDS and the RCMC match well. The PCB board changes did not affect the servo speed profiles. The one thing Lionel watches carefully is the speed matching profiles when PCBs change. I designed the RCMC hardware and wrote the code, and I based the servo code directly on the DCDS code. The DCDS code was originally written by a very talented person under Lou Kovach of ICC controls fame. I picked up the DCDS code when I joined Lionel in 2006, and refined it for production of the first Legacy Loco, the Big Boy. So I can state for certain the servo for the speed controls matched on these PCBs from 2006 to present!
Original TMCC and BEMF versions of products cannot speed match to Legacy, but some compromises need to be made when locos are smaller. Normally these locos that go off the "standard", are steamers. These are less likely to lash up, especially yard goats, Heislers, etc.
