AutoTuner Master
AutoTuner Master is an advanced device designed for professional tuners, workshops, and dealers involved in modifying the software of engine control units (ECUs) and transmission control units (TCUs). Thanks to its versatility, speed, and lack of subscription fees, it is a comprehensive solution in the field of tuning.
The Master version gives us full access to .bin files (ECU/TCU binary files). This allows you, with the appropriate software such as Winols or StageX , to edit the files yourself, start working with us at ECUFILE, or outsource the work to any external company.
This programmer will allow you to, among other things:
- Read original maps from the control unit
- Make backup copies of the original software before making any modifications. Update or restore the controller to factory default software (if a VR or Update File is available)
- Recalculate the checksum and save the modified bin files. This allows for any modifications to the ECU/TCU controllers in terms of increasing Adblue/EGR/DPF power or optimizing gearbox operation.
- Perform diagnostics under load (so-called dynamic log), e.g., to verify key engine operating parameters before/after modification.
Key features of the programmer:
Versatile communication: Supports three main methods of communication with the ECU and has a built-in Datalogger:
Dataloger: This is a software module that allows you to collect and analyze data in real time from your car, while driving or on a dynamometer.
- It allows you to view real-time parameters such as:
- boost pressure,
- fuel pressure and dosage,
- ignition advance angle,
- AFR values (air/fuel ratio),
- exhaust gas temperature, intake air temperature, coolant temperature,
- engine speed, torque, vehicle speed, sensor statuses (lambda, MAP, MAF, EGR, etc.).
- Log recording: data can be saved and analyzed later in dedicated tuning programs.
- Diagnostics and testing: problem detection (e.g., turbine overload, lean mixture, fuel pressure drop).
- Tuning verification: after changing the ECU map, the tuner can check whether everything is working correctly and whether the engine is operating within safe parameters.
- No subscription fees: after a one-time purchase, users receive lifetime access to software updates and new protocols, eliminating additional operating costs.
- Support and warranty: – the standard warranty is 5 years from the manufacturer, and we also offer our technical support and remote assistance. We provide individual training at the customer’s request.
- Wide compatibility: Supports over 4,000 control units in passenger cars, trucks, motorcycles, water scooters, ATVs, boats, and tractors. Thanks to regular updates, the list of supported units is constantly expanding.
- Speed of operation: Thanks to the Cortex-M4 processor, the device provides instant data reading and writing, which significantly increases work efficiency.
- Data security: Automatic backup of ECU data to the cloud provides an additional layer of protection against data loss.
- Intuitive software: The computer application guides the user step by step through the tuning process, offering visual support and detailed instructions.
