@gunrunnerjohn posted:The TMCC BASE1/CAB1 only operates in relative speed step mode, I don't think it supports momentum properly. I did my testing with the Legacy system as the TMCC control operates in absolute speed step mode and does support momentum.
Momentum definitely works with the TMCC Base/CAB-1 with TMCC locos that have Odyssey. It works perfectly with my CC-II PRR Baldwin Sharks. With Legacy locomotives when using a TMCC CAB-1, the L, M, and H buttons select 32, 100, and 200 speed step mode.
I'll double check my CC-M equipped locos in 32-step mode. However, in my case I'm using Lionel R2LC-C08 boards NOT the special ERR R4LC-C08 boards. But I'm going by what I ordered from Lionel. If they secretly replaced them with R4LC versions then I don't think there is a way to discern the difference.
