about us

Who is SXTHNK

  • SXTHNK tuning is the tuning division of SXTH Element Engineering, a company that has been in the automotive industry for over 10 years.

    We provide high quality, professional vehicle ECU software and devices for flashing ECUs, which are the electronic control units that manage various aspects of your vehicle's performance.

    SXTHNK tuning specializes in Korean vehicles, such as Hyundai, Kia and Genesis, and has a focus on user experience.
    We design our products and services to be easy to use, safe and reliable.
    We also offer technical support and customer service to help you with any questions or issues you may have.
    We are proud to be the first in the world to offer at home OBD flash tuning on many popular Korean cars, such as the Hyundai Veloster N, the Kia Stinger GT and the Genesis G70.
    OBD flash tuning allows you to modify your vehicle's ECU software through the OBD port, which is the diagnostic port under your dashboard.
    This means you don't have to send your ECU to us; you can do it yourself with our devices and software in minutes.

    Our goal is to help our customers unleash the full potential of their vehicles with our innovative and reliable products and services.
    Whether you want more power, smoother driving or custom features, we have the solution for you.

    SXTHNK tuning is more than just a name and high quality professional ECU software. It's a way of thinking that drives us to create the best possible products and services for our customers.
