### 1/5 — Funktioniert leider nicht mit den neuen EP 8

*2026-03-28*

Funktioniert leider nicht, man muss wie schon beschrieben ein Downgrade machen. Schade Geld weg und kein Ergebnis vielleicht kommt ja mal ein Update

**Developer response:** Vielen Dank für Ihr Feedback. Mit Version 2.0 ist der für die Geschwindigkeits- und Regionskonfiguration erforderliche Firmware-Downgrade für EP8 / EP800 jetzt direkt in eTuning integriert und läuft automatisch innerhalb der App.

Falls Ihr Bike einen EP801-Motor verwendet, ist für die Geschwindigkeits- und Regionskonfiguration eTuning für Windows zusammen mit dem Shimano SM-PCE02 Interface erforderlich.

Für andere unterstützte Funktionen kann die iPhone-App je nach Motormodell und Firmware-Version weiterhin funktionieren.

### 1/5 — Unausgereift und unseriös

*2026-03-16*

Die kostenpflichtige Aktivierung der App auf eine Motorseriennummer hat beim ersten Versuch und auch nach langem Warten nicht funktioniert.
Zwei Tage später hat es dann bei einer nochmaligen Buchung und nochmaligen Zahlung (wieder auf die gleiche Motorseriennummer) funktioniert.
Der Anbieter verweigert die Rückzahlung der doppelt gezahlten Lizenzkosten. Die gesamte finanzielle Abwicklung erscheint unseriös.

Es soll vermutlich absichtlich unklar bleiben, wer der Anbieter dieser Software ist. Es wird gegen die EU-Impressumpflicht verstoßen.

### 1/5 — Ep6rs

*2026-02-20, version 1.0.7*

Payer et pas possible de programmer déçu totalement

### 1/5 — Purchased us region

*2025-12-07*

I have purchased us region but unable to download downgrade the etuning apps.. it’s so complicated for iphone users.. wasting my money to purchased ada cant do anything to it..

### 1/5 — Constantly crashing when trying to pair

*2025-08-30*

### 1/5 — Scam

*2025-07-18, version 1.0.7*

I paid 24€ for nothing, it didnt change speedlimiter of my bicycle. I’ve been waiting forever and nothing happend

### 1/5 — App ist unbrauchbar

*2025-06-27*

Man kauft eine teure Lizenz und trotzdem ändert die App NICHTS es wird nicht einmal der Radumfang geändert. Hoffe sie zahlen das Geld zurück

### 5/5 — DU-EP800 Works as described

*2025-06-01, version 1.0.7*

David was quick to reply to my questions. The app… providing you follow all the instructions does what it claims. You can definitely do this to the DU-EP800 motor. But just remember that at step 5, you need to unzip the down loaded zip file and copy them (.DAT) x 2 to the FW folder. Once I did this it went smoothly and I able to make the change I wanted. Thank you David 😊🙏

### 1/5 — Non va

*2025-05-09, version 1.0.7*

Appena comprata: 25 euro iva compresa non fa cambiare nessun parametro. Praticamente una fregatura. Motore Shimano EP600rs

### 2/5 — Bonne application mais ..

*2025-04-09, version 1.0.7*

Application pratique pour consulter le % de la batterie de mon ORBEA mais qui m’a causé des soucis. 
Je m’explique. L’application doit de déconnecter du moteur a l’issue de l’utilisation mais il m’est arrivé que l’application ayant planté et ne s’étant du coup pas déconnecté de mon bike ; je me suis retrouvé à ne plus pouvoir récupérer le contrôle de mon bike.
