E-TUBE PROJECT is an application that allows you update your bicycle's firmware and change Di2 settings by connecting wirelessly.

Customize functions and operations as you please. Discover the settings that match your personal riding style.

Update firmware
The application automatically checks for new firmware each time it is started. This allows you to keep all units up-to-date at all times.

Error check
If you notice an abnormality, immediately perform a diagnosis using the app. The unit at issue is identified, allowing you to quickly and easily seek repairs.

This function allows you to connect one or more units and read or write all the settings of those units at a time. The readout settings can be saved in a file. The settings can also be successively written to multiple bicycles.

As disappointing as the whole Di2 experience

I will be mature and resist the temptation to use this opportunity to vent my spleen about the whole Di2 experience (it’s crap).
I can’t help but think I’ve just spent over 1K on an arguably pointless upgrade only to discover that I am part of the products development.
This app is hit and miss to put it mildly. It simply does nothing, I cannot get a Bluetooth connection despite trying everything I can possibly think of. The manufacturers reference data has no troubleshooting information.
Clearly the worst thing about this app is that if you are downloading it and attempting to use it then you have already wasted your money on Di2.

You read all the horror stories of immediate firmware updates and then you bike becoming a one speed, and think it was just their bad luck... No!!! Rubbish, followed install and step by step instructions exactly of course crashed 50% into firmware update that can only be done over Bluetooth, and now my £100 wireless receiver is worthless have tried to reconnect to it 50 times, no luck, unplug battery and reconnect at least I have gears again. Terrible app

DO NOT BUY DI2, get Force eTap AXS instead

I’m regretting. The mech actually works fine, until you need E-Tube. And you’re doomed. I’ve grown in the 80s impressed with mighty Japan, but E-Tube is worse than those cheap Chinese copies from 20 years ago. Unbelievable but E-tube does not work with iOS 13.
