Modern ECU/TCU units store software that can be modified to provide more power, lower fuel consumption, or eliminate issues such as DPF and AdBlue errors. But for the process to be successful, you need a combination of reliable hardware and a professionally prepared software file.

This is where files.carhack.net comes in – an online platform that simplifies the entire process and makes working with tuning files fast, secure, and accessible. Let’s go through the four main steps of the platform and how they work for you.


Step 1: Upload the Original File

Everything starts with the vehicle or machine you’re about to optimize. Using professional tools like DFOX, KESS3, FLEX, or Autotuner, the original software is read from the ECU or TCU. This is a critical step because the “original” serves as the base for any modification.

Uploading the file to the platform is intuitive and quick. Once extracted, you upload the file to your account on files.carhack.net. The system accepts multiple formats and automatically checks the file’s integrity to ensure that you’ll receive a correct and working result. This eliminates the risk of errors from the very beginning.

It’s important to note that working with the original file preserves all vehicle-specific information – VIN number, ECU identification, and all individual parameters. This guarantees that the modification will be tailored specifically to the vehicle, and not a “universal” file that might cause issues.


Step 2: Choose the Desired Services

After uploading the file, the platform allows you to select the exact modifications you want. The interface is clean and user-friendly – simply check the boxes for the services needed, without complex menus or extra details.

The most commonly requested services include:

The big advantage here is flexibility – you can combine services. For example, if you’re having issues with the DPF but also want a Stage 1 performance upgrade – both options can be selected at once. This saves time and allows full customization based on the client’s needs.


Step 3: Professional Modification by CarHack

Once your request is submitted, the file is processed by the CarHack team. There are no automatic generators or generic databases involved. Each file is reviewed individually and modified with attention to safety and optimal engine or transmission performance.

Our specialists analyze fuel, pressure, ignition maps, and manufacturer-imposed limitations. Depending on the selected services, systems such as DPF, EGR, and AdBlue are removed or adapted, or adjustments are made to increase performance. All of this is done within the technical limits of the specific engine and gearbox.

This is why it’s worth trusting a professional platform – a poorly made file can cause damage, trigger limp mode, or even lead to engine failure.


Step 4: Download and Write the Final File

Once the file has been processed, the modified version is available for download directly from your profile in the platform. This eliminates the need for emails, chats, or additional communication – everything happens online, fast and transparently.

The downloaded file is then written back into the ECU/TCU using the same tool you used to read the original. The process is standard and takes only a few minutes. The difference is that this time, you're uploading an optimized file tailored to your or your client's needs.

The advantage is not only in speed but also in traceability – the platform keeps a history of all uploaded and processed files, giving you full control over your modifications. This is especially useful for workshops working with many clients who want to maintain an archive.
