Uhh... this isn't really true. A standard TMCC locomotive only responds to 32 steps, there is no way it'll run 128 steps without some different upgrade boards or a firmware upgrade (which does not exist).

The ERR Cruise Commander M upgrade will update a TMCC locomotive with modular electronics to 100 steps, and a Legacy locomotive has 200 steps.

One thing for conventional operators is the TPU in conjunction with the Legacy controller offers finer control than the PowerMaster, or at least that's what has been said. Since I don't run conventional, I've never tested this capability.
