SCHNELL Flash - Your OBD Flasher

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

You can manage all the vehicles you use with your QUICK Flashers through the garage. Each device is linked to a VIN, but multiple vehicles can be registered and managed within the app.

As soon as you read out your vehicle with SCHNELL Flash, the original ECU file will automatically be sent to us. We will individually optimize your file for your vehicle and send it back to you directly via the app – ready for flashing.

FAQ
You have questions, we have answers.
Do I need Wi-Fi / internet?
Yes, a 4G / 5G or Wi-Fi connection is required to send the read-out file from the control unit to the cloud interface.
Can I flash multiple vehicles with one SCHNELL Flash?
No, the RAPID Flasher is linked to the selected vehicle by its VIN. However, you can manage multiple vehicles with one app.
Do I need a charger?
We recommend performing all read/write operations with a battery charger connected to ensure stable voltage and prevent the vehicle from shutting down.
Does my ECU require an OBD unlock to be flashed via OBD?
Some ECUs need to be unlocked before the OBD flash. In this rare case, the ECU must be removed and sent to our partner workshop in Thuringia. The master car repair shop is centrally located in Germany to keep shipping and processing times short. The OBD unlock procedure costs €149— of this amount, we will cover €50 as a gesture of goodwill, so you will only pay €99.
Is removing the control unit difficult?
Removing the control unit is quick and straightforward. Many customers remove it themselves — alternatively, any independent workshop can help.
If you are unsure, we are happy to assist you:
- We will give you step-by-step instructions
- Upon request, we can explain the process to you by phone or chat
- You can also send us photos, and we will help you live
Where should I send my control unit and how should I package it properly?
Please send the removed control unit to our partner workshop in Thuringia:
Dorfstraße 41, 99438 Vollersroda
Please pack the control unit well-padded and send it insured with tracking.
