i have a 9070 Di2 rear derailleur

it is setted to do 10 jumps every 1.85 mm as road cassette spacing

can i modify the spacing amount ?

SRAM XX1 mtb cassette is 11 speeds but with a 2.3mm spacing ( as 10 speeds road , not sure about measure, but like road and mtb cassette )

No because the 9070 cage is way to short to clear the 42t cog.

I have not seen an option to change shifter spacing using the software.

mine never worked. so don't know about pce-1. pce-1 is a diagnostic tool, so don't think there is an option to change shifter spacing there.

The PCE-1 and E-tube software does not allow for changing the shifting from 10 speed to 11 speed or the throw for each shift step. This would require someone to decompile the actual firmware and then figure out a way to recompile it then have the E-Tube software reflash it. None of this is trivial. Have fun with your PCE-1 but all you will be able to do is flash Shimano's existing firmware, tweak button assignments, change multi-shift settings and do some system diagnostics.

Shimano is one of the worst at documenting what they changed in their firmware, they might as well not release change logs since they are essentially useless as they are currently written.

Haven't played around with it for a long time so things may have changed, but I remember our rep telling us 9070 could be used for both 10/11s.
