Upgrade your tuning workflow with a toolset designed to boost capability and reliability.
This master kit is built to support modern tuning professionals who need dependable read/write options for a wide range of vehicles. It includes updated software versions for both KESS and KTAG, ensuring improved compatibility, smoother operation, and better overall handling of protocols used by newer ECUs.
Both interfaces integrate easily with popular Windows systems, giving you a familiar environment for editing and managing ECU files.
Updated software—KESS 2.80 and KTAG 2.25—offers enhanced functionality and better support for varied vehicle types.
You can download additional ECU software tools as optional add-ons when needed, expanding the tuning capabilities even further. The newest KESS version provides improvements over earlier revisions, making tasks smoother and more intuitive.
The red PCB version of the kit is engineered with carefully selected components to ensure long-term stability, clean signal transmission, and reliable ECU communication.
Differences between KESS 5.017 and KTAG 7.020 mainly involve connection methods and coverage. KESS typically handles OBD-based tasks, while KTAG excels in tricore, BDM, and boot operations, making it ideal for deeper ECU work and diesel platforms.
KESS offers broad brand coverage and includes many open protocols. It supports multiple languages and operating systems, expanding accessibility for technicians around the world.
KTAG supports even more protocols—especially useful for heavy-duty, agricultural, and diesel tuning—making it a strong companion to KESS for complete workshop capability.
A GPT cable is also included, enabling work with newer tricore microcontrollers where password unlocking is required for deeper ECU access.
The kit includes multiple built-in protective features such as real-time voltage checks, automatic checksum correction, recovery functions, and integration with ECU editing software.
Below is a rephrased and clarified Q&A section to help you troubleshoot common issues:
Why does a 4GB SD card show only around 120MB available?
This SD card uses encryption, and the hidden data does not appear in normal file views. The visible capacity is expected and not a defect.
What should I check if the software reports “connection not established”?
Verify that the device drivers are correctly installed in your system’s device manager.
How do I fix a checksum error message?
Installing Microsoft Visual C++ packages (2005, 2008, 2010) often resolves it, or you can request updated DLL files if needed.
What causes a wake-up error?
This may happen when the wrong fuel type is selected or if there is an issue with power or ECU connection. Reinstalling the software or testing a different SD card may also help.
Why does an external exception error appear?
This sometimes occurs when mixing hardware or software not designed to work together. Use the correct software, delete the previous installation, and reinstall it to the primary system drive.
