KESS3 Slave — Pure Tuning

This is the Kess V3 with the Cars OBD protocol only if you need more protocols checkout this link

Are you currently outsourcing AdBlue, EGR, DPF, and other jobs to an external specialist?
Then this tuning tool is the perfect solution for your business!

Outsourcing costs unnecessary time: the specialist isn’t immediately available, which means the car stays longer or the customer has to come back later.

With this tuning tool, you can handle these jobs yourself in just 20 minutes!

Here’s how:
✅ Read the ECU (similar to a diagnostic device)
✅ Upload the file to our portal
✅ Receive the modified file within 20 minutes
✅ Write it back to the car
✅ Complete the job and verify the result.
⚠️ Note: These free credits are only valid for the slave tools connected to our master tool.

Keep in mind: The Kess V3 is one of the cheapest tools to purchase on the market, but it costs €590 per year to receive updates.
This makes it more expensive in the long run than other tools. We personally recommend the Autotuner, which has a higher purchase price but includes lifetime free updates.

The Kess V3 is user-friendly, but to ensure you can confidently use it, we offer a free introductory session where we walk you through the tool and tune a car together.

FAQ

Is tuning safe?
All our files are carefully tested on our 4x4 dyno test bench. Additionally, we offer a 100% software guarantee on the files, meaning you always receive a working file—otherwise, you get your money back.
For companies with certain certifications, additional options may be available. Ask us for more information.

How long does it take to recoup the cost of the tool?
Your payback period depends on your purchase price, activated protocols, file-service costs and the margin you retain per completed job. Calculate it from your own figures before ordering; no fixed profit or payback period is guaranteed.

Which car models can I tune with the Kess V3?
Check your vehicle and ECU/TCU in the official Alientech vehicle list before ordering. Confirm the required connection method and activated protocols for the work you plan to do. Compare KESS3 Slave software protocols.
