Well, some success has been had... With CV2=0, CV5=50 and CV6=20.... BUT.... I reprogram the CV's, then go back to previous settings, and my results change !?! Right now I am not sure whether something funky is going on with the algorithms in the decoder, or whether it is in RM... Top scale speed (58kph) has varied from circa 67kph down to 47kph - for no logical reason that I can discern... Does BackEMF mess with "stuff"? The speeds for Cruise and Top Speed are at around the right levels - Shunt speed has varied from a best of 27kph to worst of 37kph (all with the same CV settings - but after complete halt and reprogramming) Starting setting on RM is 5kph - I cannot seem to get it to start at the lowest 2kph setting. - and that measures at scale 16kph. All things considered, with RM set to scale speed, the Pocket rocket is relatively tame. Really need to understand how the decoder interprets the settings, and the interactions with RM better - might result in more consistency. But the settings I have used here might give someone else a head start (and save hours of measurement and experimentation).
