ECU/TCU calculations for every vehicle - We reinvent Chiptuning for workshops, for the present and

The KESS3 hardware is engineered to deliver professional-grade performance for users at every level — from emerging tuning enthusiasts to advanced mechatronic specialists.
Its cutting-edge architecture combines powerful processing capability, rugged automotive-grade construction, and intelligent interface design to communicate with virtually any engine or transmission control unit on the market.

Designed for maximum flexibility, KESS3 enables seamless interaction with ECUs and TCUs via OBD, Bench, and Boot modes — all within a single, compact device.

Exceptional speed, high data integrity, and intuitive connectivity ensure fast and secure operations whether you’re tuning, calibrating, or performing advanced ECU/TCU service functions.

The KESS3 Protocols/software are the core communication pathways that allow seamless interaction between the KESS3 tool and a vehicle’s Engine Control Unit (ECU) or Transmission Control Unit (TCU).
Each protocol defines the specific method of reading, writing, and managing data inside the control modules, enabling precision tuning, calibration, or repair functions across thousands of makes and models.

Built for everyone — from performance tuners and automotive engineers to advanced mechatronic technicians — KESS3 delivers a fast, intuitive interface that simplifies complex electronic communication.
Its software-driven protocol structure ensures reliable access to ECUs and automatic gearboxes via OBD, Bench, or Boot connection modes, making the process efficient, secure, and accessible to all levels of users.
