Hi Jaseem,

I only know what I have read regarding WinEQMOD which I have been using for over 10 years. The Custom Mount option provides a means of supplying parameters to replace the values the software uses based on the mount ID returned by the Skywatcher controller board. INDI/Eqmod must be using the same parameters in it's calculations for GoTos, slewing and tracking rates. The override values entered should be persistent between sessions and probably some indication on the main INDI/Eqmod dialog.

This is Win/EQMODs parameter entry dialog. You can select a mount/ratio from a list provided in a text .ini file or type in your own (if your brave!).
