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.

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.

Kind of pointless

Come on Shimano, you can and NEED to do better than this! While the app does work with the e8000 on my Scott Genius, I find the features laughable compared to the Specialized Mission Control.
The only thing useful, to a degree is the ability to change the power settings in Trail and Boost. This would actually make more sense to have access to from the display of the bike and how often will you do this anyway?
There is no other useful info, no total hours or charge cycles. No actual percentage of battery charge aside from the bars also shown on display and battery itself.
Specialized can even monitor and adjust power levels based on the amount of miles you plan on riding!
I expected way more from a company the size of Shimano who also sells more Ebike systems than any competitors.
The e8000 is great, how about spending more than 45 minutes developing an app that can really showcase it’s abilities?

Works well, good app

This app works well. Allows you to customize shifter parameters to accommodate different bike configs. Can also update firmware, see battery life, and adjust to multi shifting and shifting speed. Pretty neat addition to electronic shifting.

However, it hasn’t worked ever since I update the software on my iPhone. The gear just keeps spinning and nothing happens. Does anyone else have this issue? Is this app compatible with new iPhone software?

Heed the warnings you read here, fellow Di2ers.

First day with my bike, and I had the EW-WU111 ready to go. Everything was working fine until I opened this app, then my system was bricked. I managed to restore it all, tried again, and bricked.

Don’t bother with this horrible software. If you do end up shutting down your entire Di2 system, unplug each of the cables from the junction box, and disconnect the junction box from the battery. I also had to unplug the Di2 wires at the derailleurs. Plug everything back in and you should be good to go.
