Unrestricted ECU Tuning for Professional Calibrators
The Autotuner Master Tool is characterized by its unparalleled ease of use, high efficiency, and ultra-fast processing speeds. Thanks to its advanced internal Cortex m4 processor and ECU communication optimization, reading memory contents—including Dflash, Eflash, and EEprom—is incredibly fast. It is a universal tool capable of reading information from most modern ECUs and microcontrollers on the market via standard OBD or in Boot Tricore mode.
The Master Advantage: Total Independence
Unlike Slave versions, the Autotuner Master Tool gives you raw access to 100% unencrypted data files. This provides the ultimate freedom to develop your own custom calibrations, edit binary files in software like WinOLS or ECM Titanium, and eliminate your reliance on third-party file providers. Additionally, owning a Master tool allows you to encrypt files and supply them to your own dedicated network of Autotuner Slave dealers.

Intelligent Software & Built-In Support
Autotuner removes the guesswork from complex ECU tuning. The software displays all compatible vehicles in a simple, easy-to-navigate list. Once a vehicle is selected, the tool helps you quickly locate the OBD diagnostic socket or the ECU itself.
For bench and boot connections, a specific help section is available directly within the software. It guides you step-by-step through the process, illustrating exact pinouts with high-definition photos. All of this support information is continuously updated and provided completely free of charge.
Advanced Safety Features
Safety is critical when modifying engine electronics. The Autotuner systematically performs a backup of the TriCore password online, ensuring you have the necessary security data safely saved during the read/write process.
