Alientech Kess 3 Hardware

The Alientech KESS3 is the next generation of ECU tuning tools, replacing the hugely popular KESSv2 and K-Tag devices that have dominated the market for over a decade. With its advanced design and powerful processor, the KESS3 delivers lightning-fast performance and unmatched flexibility for tuners and remapping professionals.

Master or Slave Configuration

When you purchase your KESS3 hardware, you can choose to activate it as either a Master or Slave tool.

• KESS3 Master gives you complete control, with full access to reading, editing, and writing tuning files.

• KESS3 Slave is designed to work in partnership with your chosen Master, offering a cost-effective solution with professional support for tuning files.

At Ai Remap, we can provide both options and guide you through selecting the right setup for your needs.

OBD, Bench & Boot Tuning

One of the standout advantages of the KESS3 is its ability to handle multiple tuning methods from a single device:

• OBD Tuning – Fast, simple, plug-and-play connection directly through the vehicle’s diagnostic port.

• Bench / Boot Tuning – For deeper access and more complex remapping tasks, ensuring full flexibility.
  You can select either option or combine both for maximum coverage.

Wide Vehicle Coverage with Protocol Packages

Your chosen protocols determine which vehicles you can tune. Options include:

• Cars & Light Commercial Vehicles

• Bikes, ATVs & UTVs

• Agricultural Vehicles, Trucks & Buses

• Marine & PWC applications

Each category is available with OBD, Bench/Boot, or both – allowing you to build a tool that perfectly matches your business.
