Dashboard

In the dashboard, you can chat directly with us, read your vehicle data, and send us the file for optimization. Once your custom-tuned file is ready, you can flash it back to your vehicle with just one click – quickly, safely, and entirely via OBD.

garage

The Garage allows you to manage all vehicles used with your SCHNELL Flashers. Each device is linked to a chassis number, but multiple vehicles can be registered and managed within the app.

Read and send file

Once you read your vehicle with SCHNELL Flash, the original ECU file is automatically sent to us. We optimize your file individually for your vehicle and send it back to you directly via the app – ready to flash.

FAQ

You have questions, we have answers.

Yes, a 4G / 5G or WLAN connection is required to send the read file from the control unit to the cloud interface.

No, the SCHNELL Flasher is linked to the selected vehicle via the chassis number. However, you can manage multiple vehicles with one app.

We strongly recommend performing all read/write operations with a connected battery charger to ensure a stable voltage and prevent the vehicle from shutting down.

Some control units need to be unlocked before the OBD flash. In this rare case, the control unit must be removed and sent to our partner workshop in Thuringia. The automotive repair shop is centrally located in Germany to ensure short shipping and processing times. The OBD unlock procedure costs €149 —we will cover €50 of this amount as a goodwill gesture, so you only pay €99 .

Removing the control unit is quick and easy. Many customers do it themselves — alternatively, any independent garage can help.

If you are unsure, we are happy to support you:

  • We'll give you step-by-step instructions.
  • We can explain the process to you by phone or chat upon request.
  • You can also send us photos, and we'll help you live.
