eTuning - for Shimano ebikes 4+

Invested a license and then found that the app will not fully function with the latest Shimano firm ware unless. You revert to an earlier version and that is at least two versions ago. I can not recommend this app.

I Downloaded this to change “derestrict” the speed limiter as well as tune the assist in different modes. Being that my bike was a 27.5” wheel, my bike was limited to about 16mph in the United States. I was looking for a limit of around 20-25mph based on the trails around me. This app is able to provide of speed much higher than that if you desire.

I had to download a file viewer for my iPhone 12 and modify the E-Tube Shimano app to install an older software version to my E8000, but following the instructions on the eTuning webpage was a breeze. After that I was able to modify anything I wanted to on my motor.

Another feature I liked was being able to adjust your assist level in 1% increments up to 300% as well as max torque output in all 3 modes of eco, trail, and boost.

Overall this app did everything I wanted at less than $29!

Way easier than all the stuff I read online, you connect with the push of a button and they have setting categories that make it so easy to customize and fine tune your motor to your preference. I mountain bike regularly and to be able to customize all functions with ease is critical. I highly recommend this app.
