I've finally found time to place this little jevel on tracks
In short:
Little disppointed by hi-speed at 128 steps (PowerCab) : way too much
Starting speed at low step was around 10 or so.
So... Startup my JMRI and ... found just Vstart and few other CV are available.
Lowering Vstart to Zero.. give me a start point at step 5, no less.
Hi speed : I was able to set at a resonable value.
At the end, I want replace the decoder with one of the Zimo I already have and that usually give me so much good feelings.
Problem (not really, but...) : all wires from boiler to tender are Black!
IF one don't want to pull-up the boiler ... no way to know wich wires are Motor, tracks front light?
Have somebody do same job and know the assignment on the solder pads in the tender board?
Thanks for any help, friends.... before dismount the loco
Take care
Enzo Fortuna
