Kess 2.90 -

: Connect the KESS tool to the vehicle’s OBD-II port . Perform an ID check in the software to verify communication before attempting a full read. 3. The "Story" of the Procedure

: Send this "read" file to a master tuner or use your own software to create a modified version (e.g., for a stage 1 tune or DPF delete).

Typical advanced workflows

Setting up a Kess 2.90 clone is a process that requires patience and careful attention to the tool's specific requirements. Because it is not an official product, there is no official installation wizard.

However, because:

: Kess V2 is highly reliable for older systems like EDC15 and EDC16 , but use caution with newer EDC17 systems, as they may require K-TAG for safe bench-tuning.

: Allows users to read and write the ECU directly through the vehicle's diagnostic port without needing to remove or open the unit. Automatic Checksum Correction Kess 2.90

Although Kess 2.90 does checksum correction, always verify the checksums to ensure the file integrity before flashing.

Connect the hardware interface to the vehicle's OBD2 port and link the USB interface to the computer. Open the software, select the specific make, model, and engine variant, then execute the "ID" function to pull the hardware and software part numbers. Once verified, select "Read" to extract the original binary file. Step 3: File Modification : Connect the KESS tool to the vehicle’s OBD-II port

The Kess V2 2.90 represents the final "Golden Era" firmware for the Alientech Kess V2 hardware before the industry transitioned to the Kess 3 platform. It is widely considered one of the most stable and reliable releases for the V2 hardware. However, as of 2024, this tool is strictly considered . While highly capable for older vehicle protocols, it lacks the support infrastructure for modern ECU architectures (UDS, MDG1, MG1).
