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.Show lessPh0re
WARNING! USE AND RISK BRICKING YOUR BIKE
Tried to update my DI2 using this mobile app and it bricked my system. It would not shift, nothing, absolutely unresponsive. A quick search online and I found out that this is a common occurrence. In most cases, unless you have a special PC interface you’ll have to take your bike to the shop to have them update the software. Someone said should sue Shimano for this piece of crap. I wish I could give it a negative 5 stars for the time and money it cost me. Next time I’ll buy Sram.Show lessrixsurfer
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?Show lessT Van 1975
Not Worth The Frustration - Do Not Download
I never write reviews but want to forewarn anyone who attempts to use Shimano’s e-project software. Don’t!!! It doesn’t deserve 1 star but it’s the default. I just spent 3 hours trying to download the software without success. Bluetooth repeatedly dropped the connection and then when it did connect the software reconfigured all gearing which left my bike caught between gears and not rideable. Save yourself the frustration and pass on this software. It’s not worth it!!!Show lessWaste of time 2019
Issues submitting changed password
The app does not give you the ability to change the password to connect to your DI2 after setting a new password up on your PC, there is no obvious way to forget the device to try an attempt to connect from scratch.
Pretty obvious oversight.Jordan72727394
Really hard to use
I have been trying to figure this out for an hour. I changed the password because it made me but now it says the pass key is incorrect because there’s no opportunity to type it in! This is so frustrating.C Hofbeezy
Be warned
This has crashed my Di2 setup too many times, I’ll go you solution to fix. Problem is it updates firmware once it connects and if any hiccup in connection it locks the Di2 and makes shifting unusable. Fix is to disconnect every component from the battery count to 30 and reconnect. If you still insist on using, avoid the auto update of firmware by making sure phone is not connected to net via WiFi or cell. Best way is to avoid all together and use a PC version of E-TUBE to make adjustments.Show lessLost 22 still going
Bricked My Bike
I read other negative reviews and hoped Shimano would have fixed the bugs - nope! My Bluetooth connected and it offered to upgrade my new Ultegra R8000 components' firmware, then promptly encountered an error rendering my bike without the ability to shift. After a couple hours of fiddling with their not-much-better PC software (not available for Mac, mind you), I got the firmware reinstalled from scratch and it works again. But what a frustrating hassle this all turned out to be. Spend a little money to hire some software engineers who can match your mechanicals.Show lessAdam Boltz
Can't connect to EW-WU111 after upgrade to iOS 11
The app used to work fine until the release of iOS 11 recently. Now I can't connect via Bluetooth to EW-WU111 to update firmware of Di2 components, I get the error "BLE connection was interrupted, try again". I have the latest version of the app as of this moment (v3.3.0) and am on iOS 11.0 on iPhone 6. Lucky me I had another phone still on iOS 10 which I was able to use successfully to connect and update all Di2 components, including EW-WU111. Even after the update, I wasn't able to connect from the iOS 11 phone.Show lessCactusChip
Agree with auskropp, EW-WU111 doesn't work
Given the new EW-WU111 was to enable BLE for iOS app, looks like things are out of sync. In my case, I've verified all components are on the E-TUBE compatibility chart and everything works through via the wired charger connection and the PC version 3.2.
Hope the gets changed soon as the error on the 3.1 iOS app here is to upgrade the app to the latest version and try again. Hope the app is upgraded soon - very soon.Show lessJohn-4374
