You may need to temporarily disable Windows Defender or other antivirus programs during installation, as ECU tuning files are often flagged as "false positives" due to their deep system access.
Best used with KESS V2 Firmware v5.017 (Red PCB versions are generally considered higher quality).
Includes real-time battery voltage monitoring and a full recovery function in case of communication interruptions.
Windows XP or Windows 7 (32-bit is highly recommended for driver stability), though Windows 10 is supported by some distributions.
