Do the donwgrade with Android, since it is much easier than with iPhone and once completed you can use eTuning with your iPhone forever. To downgrade either on iPhone or Android you do not need to have purchased an eTuning license.


Why doesn't eTuning detect my bike's screen?

All Shimano displays do not have bluetooth. The settings that eTuning modifies are saved in the motor, not on the screen. If you wish you can temporarily borrow a screen or interface with bluetooth to modify the settings of your motor

My screen has bluetooth and eTuning does not detect it

Completely close all the apps on your mobile. If you don’t know how to do it, you can restart your phone. Connect with E-tube (Shimano app). Once connected, close the E-tube app completely. Now you can connect with eTuning.

eTuning asks me for a password to connect.

This is your screen password. If you have not changed it (in E-tube) the default password is 000000. It is the same password that E-tube asks you to connect to your motor.

App features


It is possible to change the region to the US to have a speed limit of 32 km / h. It is the configuration that the bikes sold in the US have by default. Changing this parameter is the best way to delimit the 25 km/h speed limit.

Wheel circumference

By modifying the wheel circumference to 1300 mm, speeds of up to 60 km / h can be reached. But in addition to the fact that it can be dangerous for the cyclist, the speedometer and the odometer stop working properly.


In this screen you can freely modify the cutting speed of each mode. Only works on e8000 motor and 4.3.2 firmware


In the assistance, the values ​​of each mode can be modified with much more freedom than eTube. Both the assistance (%), torque (NM), and the maximum power peak (W) can be adjusted in detail.

Assistance: How much pedaling force of the user multiplies the motor.

Torquee: Maximum torque that the motor can supply in maximum assistance.

Power: Peak of maximum power that the motor can supply for a few moments.

This setting is not available for EP8 motors, for EP8 motors you must use E-Tube to set these parameters. In the EP8 and E-tube, these parameters can be freely modified.


In these settings you can switch between manual and electronic gearbox. The number of teeth on the chainring and transmission can also be adjusted. Setting the wrong settings can cause the assistance to not work and the error 010 appears. To fix this, you have to reset the initial settings.


In the light section you can turn on and off the bike light or the USB port. You can also modify the reserve time, this parameter affects the battery. The reserve time is the minutes that remain of the light reserve when the battery for assistance is exhausted.

Set zero to maximize the battery charge available for assistance.

Motor angle

It is the angle that the motor is mounted with respect to the ground. On some bikes, modifying this angle can increase walk mode. Generally modifying this parameter does not affect anything.


In the information section you can find in addition to other data the status of the battery. In this way you can check when the battery has lost its effectiveness and it is necessary to replace it.
