Autotuner Slave to Master License Conversion
Unlock Full Independence, File Editing, and Dealer Network Creation.
Total Control of Your Business. This license conversion service transforms your existing Autotuner Slave tool into a fully independent **Master** device. Instead of reading encrypted files that must be processed by a specific Master tuner, your tool will read and write **unencrypted (open) binary files**.
This is a permanent, high-value upgrade that allows you to manage your own tuning files, edit maps using software like WinOLS, and even start your own file service by linking Slave tools to your new Master unit.
Master Advantages
- ✓ Open Files: Edit maps in WinOLS without reliance on a file provider.
- ✓ Dealer Network: Recruit and manage your own Slave users.
- ✓ Permanent: A one-time digital upgrade.
- ✓ Cost Savings: Significant ROI by eliminating file service fees.
Key Conversion Benefits
Unencrypted Binaries
Once activated, the tool will read and write files without encryption, giving you the raw data needed for professional map development and modification.
Full Autonomy
Eliminate dependence on the original Master tuner. You control the software, file sourcing, and modifications directly.
Immediate Access
The hardware (OBD, Bench, Boot modes) remains the same; the conversion is a digital license unlock, ensuring zero downtime for your tuning operations.
Lifetime Updates
Autotuner’s unique **No Subscription** policy applies to the Master license, guaranteeing free access to all future protocols and updates for the life of the tool.

Autotuner slave to master conversion Knowledgebase
What is the process for upgrading an Autotuner Slave to a Master?
The upgrade involves a digital transition where your tool is "unlinked" from your current Master and authorized as a standalone Master unit. At Mobile Eco Tuning (MET), we facilitate this by coordinating with Autotuner to ensure your hardware serial number is updated in their database, allowing you to create your own tuning files.
Do I need to buy new hardware for the Master upgrade?
No, the beauty of Autotuner is that the hardware remains exactly the same. The transition from Slave to Master is purely a software authorization change. This means your current investment is protected, and Mobile Eco Tuning (MET) can help you unlock the full power of the device you already own.
Will I still have no subscription fees after upgrading to Master?
Yes, Autotuner’s famous "no subscription" policy applies to Master tools as well. Once you pay the upgrade fee through Mobile Eco Tuning (MET), you continue to receive all future protocols and software updates for free, ensuring the highest possible ROI for your tuning business.
Can I read "Open" files immediately after the upgrade?
Absolutely. Once the upgrade is processed, the files you read from an ECU will no longer be encrypted to a specific Master. You will have access to the raw .bin files. Our team at Mobile Eco Tuning uses Master tools to have total control over the calibration process, a step we highly recommend for growing businesses.
Does the upgrade require my Master's permission?
Yes, in the tuning industry, a Slave tool must be "released" by the current Master before it can be upgraded. Mobile Eco Tuning (MET) can advise you on the professional etiquette and technical steps required to ensure a smooth transition from your current file provider.
How long does it take for the Master activation to go live?
Typically, once the release is confirmed and payment is processed, Autotuner activates the Master status within 24–48 hours. Mobile Eco Tuning (MET) prioritizes these requests because we know that being able to write your own files is a major milestone for your workshop’s independence.
Can I start taking on my own Slaves after this upgrade?
Yes, as soon as your tool becomes a Master, you have the authority to link Slave tools to your account. This allows you to build your own network and sell your tuning files. Mobile Eco Tuning (MET) can provide the technical support needed to manage your new Slave network effectively.
Is there a risk of losing my previous Slave logs?
Your history remains associated with your account, but the primary change is your ability to handle unencrypted data. If you have questions about legacy files, the Mobile Eco Tuning (MET) technical support team is available to help you navigate your Autotuner dashboard during the transition.
Does this upgrade cover OBD, Bench, and Boot protocols?
Yes, the Master upgrade unlocks the full suite of protocols across all connection methods. Whether you are tuning via the OBD port or performing a complex Bench read, you will have Master-level access. Mobile Eco Tuning relies on this full access for specialized performance projects.
Why should I buy this upgrade through Mobile Eco Tuning (MET)?
We offer UK-based expertise and direct communication with the manufacturer. You benefit from real-world knowledge because our company, Mobile Eco Tuning, operates as a Master user every day. Plus, you get dedicated UK-based technical support to help you through the setup.
Can I use WinOLS with my new Master tool?
Yes, the unencrypted files produced by the Autotuner Master are perfectly suited for editing in professional software like WinOLS. Mobile Eco Tuning (MET) often helps tuners transition into this professional workflow to maximize their custom tuning capabilities.
Will I still receive free technical support from Autotuner?
Yes, Autotuner provides excellent support for both Slave and Master users. However, by purchasing through Mobile Eco Tuning (MET), you get an additional layer of UK-based support from people who actually use the tool in a professional workshop environment.
Is the upgrade fee a one-time payment?
Yes, the upgrade from Slave to Master is a one-time investment. There are no recurring annual fees to keep your Master status active. This makes it one of the most cost-effective ways to scale a tuning business, a fact we frequently highlight to Mobile Eco Tuning (MET) customers.
What if I want to switch back to being a Slave?
While technically possible, it is very rare. The Master status is the ultimate level of tool ownership. If your business model changes, Mobile Eco Tuning (MET) can consult with you on the best path forward for your hardware and licences.
Does this upgrade include the "Back to Stock" features?
Yes, you retain all the safety features of the Autotuner software, including the ability to restore original files. Having Master access gives you even more control over these backups. We use these features at Mobile Eco Tuning to ensure every vehicle can be safely reverted if needed.
