Shimano DI2-9070 E-Tube Software

I haven’t seen a lot of information posted about how to do software updates with Shimano Dura Ace 9070 DI2. Here is a quick howto:

  1. Download the latest version of the E-tube Software
  2. Install the software on Windows (Mac users can use VMWare Fusion or Parallels.
  3. Launch the application.
  4. Connect the SM-BCR2 to the charging port on the junction box. The cover might be difficult to open, I had to use a screwdriver.
  5. Plugin the SM-BCR2 to your computer

From there is pretty straightforward. The software will update itself and then detect if there are updates for firmware on the various components. Below are a series of screenshots.

    Works great with Windows 7 on Parallels, but you may have to toggle the SM-BCR2 connection off, then on in Parallels’ ‘Devices’ menu to get it to recognize the device.
