DFOX is a tool designed to replace guesswork with data, limitations with freedom, and dependence on a software provider – with independence.

Whether it’s about remapping, software disabling of DPF or AdBlue – DFOX gives the workshop and/or technician what deserves respect: accuracy, correctness, and professionalism.


Inside DFOX: What Can This Tool Really Do?

DFOX is not just a tuning device – it is a high-tech system created to work with almost any type of vehicle: cars, trucks, tractors, jet skis, industrial machines.

The device supports all reading and writing modes, such as:

  • OBD

  • Bench Mode (via pinout)

  • Boot Mode/BAM

  • JTAG, when low-level access is required

In addition, DFOX works with a wide range of control units – from Bosch (EDC7, EDC16, EDC17) and Delphi, to Siemens/Continental, Denso, Marelli, Mikuni, and others. The software performs automatic calculation of Checksum, RSA, and CVN, while access to Flash, EEPROM, and microprocessor modules (MPC, Renesas, NEC) is fully integrated and stable.

Whether working with an Engine Control Unit (ECU) or a Transmission Control Unit (TCU), DFOX ensures a stable connection, reliability, and control.


Master or Slave Version: What You Need to Know

DFOX comes in two clearly defined models, tailored to the needs and experience of the user. Depending on whether you want full control over modifications or prefer to rely on a trusted partner for tuning files, you can choose between DFOX Master and DFOX Slave. These two modes offer different levels of autonomy, cost, and responsibility.

DFOX Master is the tool for those who not only perform tasks but create solutions. Chosen by technicians experienced in writing and adapting ECU and TCU files, it provides full control over the process – from reading to writing. It allows implementation of custom settings such as DPF/EGR/AdBlue OFF, Start-Stop deactivation, TVA limits, and off-road configurations.

Compatible with all major operation modes, the Master version is the ideal choice for those who want to be fully independent in diagnostics and tuning.

On the other hand, the DFOX Slave version is perfect for mechanics and small workshops that want to start offering tuning services without the need to write files themselves. Here, the read ECU data is encrypted and sent to a trusted Master account, which edits and sends it back. This way, anyone can load the ready version into the ECU without risk or technical challenges.


Why Professionals Choose DFOX Over Other Tools

  • Versatility and flexibility – DFOX supports a wide range of vehicles and control units, including specialized ECUs for agricultural and construction machinery.

  • Master/Slave model – allows a smooth transition from starter to professional tuning without new investment.

  • Cost-effectiveness – lower licensing fees in Slave mode without loss of functions.

  • Reliability – Professionals describe DFOX as a reliable and powerful solution, preferred even over tools like KESS or Autotuner for certain tasks.
