XeRun programming box

[Hog]

I'm running a HW / XeRun ESC in my B44, and really would like to have a better understanding of the various adjustments that can be made to it.

I've got the small digital setup box, but can anyone give me (preferably in relatively simple terms) what each of the setup options on the programming box actually does? I'm clear on the simpler things like brake force but it's more to do with the timing and boost parameters I need help with.

Thanks in advance........
