Shimano E-Tube Professional and E-Tube Project Cyclist are two Shimano apps that confuse a lot of riders. If you run Shimano Di2 electronic shifting or an e-bike system (Shimano STEPS), you have almost certainly come across E-TUBE PROJECT Professional and E-TUBE PROJECT Cyclist. Both configure and check Shimano electronic systems, but the difference between them is huge, especially for service and diagnostics.
As a mechanic who does Di2 and STEPS diagnostics every day, I'll explain the difference below and when each version makes sense.
In short:
- Shimano E-Tube Professional is workshop software for Windows. Together with the SM-PCE02 interface, it runs deep diagnostics and firmware resets.
- E-Tube Project Cyclist is an Android and iOS app for personalizing your shifters and doing basic checks.
- Cyclist does not catch every fault: when the system misbehaves, you need Professional diagnostics.
- We do Professional diagnostics for Di2 and STEPS systems in our workshop in Vojkovići.

Which Version Is Right for You?
If you are a rider who just wants to tune your Di2 → Cyclist is perfectly enough.
If you want a reliable service, fault clearing and a complete system check → go with Shimano E-Tube Professional.
When an electronic system starts acting up, Cyclist often can't find the cause. That is why a professional inspection is recommended.
