Ultegra Di2 - where's the "brain"?
I have an older Ultegra 6800 series Di2 groupset which is mated to an 8000 series long cage rear derailer (replaced the 6800 series short cage so I can run a 34-11 cassette) and a 6800 series front deraileur.
I think there's some shifting features that I could customize in the 8000 series groupset that I can't in the older 6800 series groupset...
...is the "brain" for shifting in the levers? or the junction box? Kinda curious about swapping the correct part out so I can better customize the syncro shifting...
...or is this just not worth the effort/cost?
Thanks!

download the app https://e-tubeproject.shimano.com/guide/ to your computer, and you should be able to customize your 6800 groupset while charging system. The "brain" is in the battery.

OP: FYI, E-Tube is not available on MacOS. Don't ask me why. I had to borrow a friend's laptop last summer to update mine.

The external batteries MUST have the proper external battery mount. This suggests that external battery brains are in the mount and not the battery. It took me three tries to get the proper external battery mount. Finally broke down and actually asked a mechanic familiar with the stuff. He print me out the Shimano interchangeability chart. If you don't have the proper battery mount the system won't even turn on. Seems as dead as a doornail.

(as long as it's compatible with BM-DN100 it'll synchro shift)
I believe Synchro shift is only available with a BT-DN110 or BM-DN100 unit. At least it was the case when I tried it.
This is what they said:

3) SC-MT800 + BT-DN110 (smart battery); 4) SC-MT800 + BM-DN100 (smart mount) + SM-BTR1 (battery)
5) SC-M9050 + BT-DN110 (smart battery); 6) SC-M9050 + BM-DN100 (smart mount) + SM-BTR1 (battery)
7) SC-M9050 + SM-BTR2 (smart battery); 8) SC-M9050 + SM-BMR1/2 (smart mount) + SM-BTR1 (battery)
1)2)3)4) - enables mtb synchroshift, enables bluetooth setup
5)6) enables mtb synchroshift, disables bluetooth setup
7)8) enables mtb synchroshift, no bluetooth radio
1) SC-M9051 + BT-DN110 (smart battery); 2) SC-M9051 + BM-DN100 (smart mount) + SM-BTR1 (battery)
