Thanks - any suggestions are welcome, but I guess there are no shortcuts, I'm just going to persevere until I get the hang of it, even if it involves some rides around the block just to see if my changes have worked!
I don't really need the Dynamic Pro and certainly not the Enduro Pro mode, but the problem is that I do want some of the other new Pro features on the 1250, like the Hill Start Pro (the auto activation of Hill Start mode on 5 degree or more slopes) and the new braking assist where if it detects the throttle open more than a smidgin during heavy braking it will just close it electronically to make your emergency braking as effective as possible. There may be other things linked to this too, but I can't think of any more at the moment. It is possible that these are not necessarily enabled by the plug but are available all the time in which case having the plug installed would not be essential. However, on principle, if I've paid for something I want it available, even if I never use it, so I'm going to have to master the ABS/DTC setting process!
