The KESS V2 is a powerful OBD2 tuning tool developed by Alientech, designed for ease of use and security. This guide provides a comprehensive walkthrough on how to use the KESS V2 for ECU programming.
Understanding the KESS V2 System
The KESS V2 utilizes advanced built-in functions to recognize ECU firmware protections, evaluate engine and battery conditions, and ensure writing completion even in case of PC malfunctions. It operates in conjunction with the K-Suite software, which provides a user-friendly interface for managing the tuning process.
The KESS V2 hardware and K-Suite software work together to provide a comprehensive tuning solution.
Getting Started with KESS V2
Before diving into the tuning process, ensure you have the necessary components: the KESS V2 tool, a set of cables (OBDII Standard, Universal, K4, and USB), and a PC with the K-Suite software installed. A 12-month subscription is often included, providing technical support, software updates, and new vehicle protocols.
The KESS V2 comes with a variety of cables to connect to different vehicle OBD ports.
Step-by-Step Guide: Using KESS V2
Here’s a detailed guide on how to use the KESS V2:
- Software Installation: Install the K-Suite software on your PC.
- Hardware Connection: Connect the KESS V2 tool to your PC via the USB cable and install the necessary drivers.
- Software Launch and Vehicle Selection: Open the K-Suite software and select the vehicle family (e.g., Cars). Choose the specific make and model.
The K-Suite software allows users to easily select the vehicle they are working on.
- OBD Connection: Connect the KESS V2 tool to the vehicle’s OBD port using the appropriate cable.
- ECU Reading: Read the encoded file from the ECU. If reading is not directly supported, perform the ID procedure.
- File Transfer: Send the read file to your tuner or “Master” for modification.
- Modified File Download: Download the encoded modified file received from your tuner.
- ECU Writing: Write the modified file to the ECU using the KESS V2. The software will guide you through this process.
Advanced Features of KESS V2
Beyond the basic functionality, KESS V2 offers several advanced features:
- Checksum Correction and Error Handling: KESS V2 automatically corrects checksums, checks for errors in the ECU, tests battery voltage, and saves injector codes before writing, ensuring a safe and reliable process.
- Recovery Function: If an error occurs during writing, the Recovery function allows you to reset the ECU to its original state.
- Tricore and Bootmode Support: For newer ECUs with advanced security, the Tricore plugin allows direct connection to programming pins for writing.
Working with KESS V2 Slave and K-TAG Integration
- KESS V2 Slave: This version allows connection to a Master tool for secure file sharing and collaboration within a tuning network.
The KESS V2 Slave allows for secure collaboration with a Master tuner.
- K-TAG Integration: KESS V2 integrates seamlessly with the K-TAG tool, allowing for benchtop ECU programming using BOOT Mode and BDM methods. Both tools can be managed within the K-Suite software.
Conclusion
The KESS V2, combined with the K-Suite software, offers a powerful and user-friendly solution for OBD2 tuning. This guide provides a foundational understanding of how to utilize the KESS V2 for various vehicles and leverage its advanced features. Remember to always follow the manufacturer’s instructions and consult with a qualified tuning professional for optimal results.
