Since you are an expert in ESU Decoders, I have another question concerning that same decoder. (Doesn't really match this topic, so I changed and expanded it a little): Lighting (bw/fw) of this loco equipped with this decoder does not correspond to the direction the loco is moving.It is just the other way round. Of course one could alter that by changing the motorleads. but I would prefer to do that by changing the CV 29 value. However, any change normal --> inverted in the "Motor Sheet" will have no effect and seems not to be accepted by the decoder. Same applies for direct manual change of the CV value. ( bit 0 = 1, bit 1 = 2, so the value should be 3).
You didn't say whether V4 or V5 and I'm nowhere near my JMRI code, DCC system or decoders so I can't answer the question about why the changed CV29 bit doesn't work.
But I will make the general observation that using the direction change bit in CV29 to fix motor and/or track wiring polarity issues rarely (if ever) fixes the problem, particularly with regards to lifting. I'm speculating (but have no evidence) that it's possible that ESU has decided to disable Bit 0 of CV29 for that reason.
If you don't want to fix the wiring issue you'll probably have to go and change Conditions in the Function Map (after having read the 1,000+ CVs in the V5 Function Map).
