Chip-tuning Software Tools

Most modern cars have preset engine operation modes that ensure high fuel efficiency and relatively low emissions levels. Unfortunately, this means that the full potential power of the engine is virtually never reached, as most power-efficient modes would require different ignition timings and fuel injection, which would lead to higher fuel consumption and, in some cases, higher emissions.

These presets are stored in the flash memory map area of the central microcontroller, known as the ECU (Electronic Control Unit) of the vehicle. This memory could not be accessed without the usage of special chip-tuning tools. Reliable, affordable and efficient chip tuning solutions are available at ECUTools internet store – just visit

ECU Map Area Editing Tools

Making alterations to ECU memory contents require a joint usage of different software and hardware tools. A standard chip-tuning toolkit consists of the following elements:

  • Adapter – hardware tool that provides direct interface between the PC with installed chip-tuning software and the ECU of the tuned car. Most adapters provide OBD II-to-USB interface, but some of them can be instead plugged to the BDM port on the chip of the ECU. Overriding most advanced ECU protection sometimes requires removing the ECU from the car and either using an electronic programming workbench instead of an adapter or using advanced adapters, which are essentially a set of wires to be connected to specific pins on the ECU.
  • Editor – this software is used to make changes to the files that were previously downloaded from the memory of the ECU. As there are more and more chip-tuning enthusiasts that do not have deep knowledge on the nuances of operation of an engine, most editors are provided with reference calibration files, which could be used as a base for making tweaks. Some editors support different ECU data formats by default, while others require buying and installing different modules to add the support for respective ECUs.
  • Flasher – this tool ensures the ability to identify, read and write the flash memory of the ECU. Some flashers utilize software-only design and rely on the usage of a compatible adapter, while others are complex software and hardware solutions that combine functions of a flasher and an adapter. Some software-only solutions are made by modular systems, while others support as many ECU models as possible. Many flashers additionally limit the number of ECUs that could be flashed without buying the subscription or special credits.
