Upgrade AutoTuner Slave → MasterAutoTuner Slave is a great start: you read and write ECUs and TCUs, while the Master prepares the modifications. But there comes a time when you want to decide about your files yourself – edit them in your own software, send them to a provider of your choice, or build your own network of Slaves. The upgrade to Master is a license change on the same device: you don't buy a new programmer, you don't lose protocols or warranty, and you gain full independence. You only pay the difference between the versions. Important: before purchasing, your Slave must be released by its current Master – without this, the manufacturer will not carry out the upgrade.
We order the upgrade from the manufacturer and oversee the process from the tool's release through to licence activation. Remember: the release must take place before purchase. If your Slave operates in the szarbi.net network, write to us and we'll release it right away.
Bought your Slave elsewhere? We'll tell you what to ask your current Master for and how to check whether the tool has been released.
After the licence change, we'll help you set up your Master workflow: file editing, checksums, working with your own Slaves and preparing files for clients.
The device stays the same – what changes is what you can do with the read file.
Frequently asked questions about the AutoTuner upgrade. Not sure if your tool qualifies? Send us the serial number and we'll check before you buy.
No. The upgrade is a licence change on the manufacturer's side – the tool stays with you and you don't send anything. After activation, simply connect the AutoTuner to the software for it to work as a Master.
The manufacturer requires the Slave to first be released by the Master it is assigned to – this is done in the autotuner.cloud panel. Without the release, the upgrade cannot be carried out, which is why the device must be released before purchase. If your Slave operates in the szarbi.net network, write to us before ordering – we'll release it right away.
Yes, provided your current Master releases the tool before purchase. We'll tell you what to ask for and check by serial number whether the release has been completed.
According to the manufacturer, reads and backups made before the upgrade will not be compatible with the tool after the licence change. If you work on cars you may want to come back to, make sure you secure their original files from your current Master before upgrading.
No. AutoTuner Master, just like Slave, has no subscription – updates and new protocols are free of charge.
Once the Master has released the tool, we order the upgrade from the manufacturer. We'll let you know the expected activation date after you place your order.
The upgrade does not change the device's warranty status – it continues to run from the tool's purchase date.
