Now at last I can control my EQ6 mount with custom gear ratio from EQMOD Indi version which I use with my Raspberry computer. Lot of work and lot of help to modify the Indi driver to accept custom gear ratio.
Here is some instruction how I made it:

Note: The gear raitio must be setup for one fixed custom gear ratio. It's done in the source code as it's now.
The driver can distinguish between an EQ6 mount with custom gear ratio and a HEQ5 with standard gear ratio. I use the same control computer for both mounts.
