Among the most trusted and widely used ECU programming tools on the market today is the Autotuner. Designed for professionals, Autotuner combines speed, reliability, and user-friendly features to deliver high-end results on a wide range of vehicles.

Whether you're an experienced tuning specialist or a growing garage looking to expand your services, Autotuner provides everything needed to safely read, write, and modify vehicle ECUs with confidence.


What is Autotuner?

Autotuner is a next-generation ECU remapping tool designed to communicate with a vehicle’s Engine Control Unit (ECU) through OBD, Bench, or Boot mode. It allows tuning professionals to read and write ECU data, which can then be modified to enhance engine performance, improve fuel efficiency, or disable specific system components (e.g., DPF, EGR, AdBlue).

Autotuner is compatible with a wide range of vehicles, including cars, vans, motorcycles, trucks, and agricultural machines.


Key Features of Autotuner

1. Multi-Protocol Access (OBD / Bench / Boot)

Autotuner provides full access to the ECU via:

  • OBD Mode – Fast and non-invasive connection through the vehicle’s diagnostic port.
  • Bench Mode – Access ECU internals without opening the unit.
  • Boot Mode – Deep-level access to ECUs for advanced functions and secure operations.

2. Extensive Vehicle Coverage

Supports thousands of vehicles from manufacturers such as BMW, Mercedes-Benz, Audi, Volkswagen, Ford, Peugeot, Citroën, Toyota, and more. New models are added regularly through free software updates.
