# How to Edit Saves for Multiplayer in ETS2

> Edit truck specs beyond in-game shop limits in Euro Truck Simulator 2. Learn safe save editing techniques for visual and mechanical convoy customizations.

## Technical Truck Customization

"Save Editing" (frequently referred to as Local Modding) is a sophisticated technique utilized by simulation enthusiasts to customize vehicles beyond the standard constraints of the in-game upgrade shops. This method enables you to architect "hybrid" trucks - such as a Scania chassis using a high-torque Volvo engine - or modify trailer weights and axle configurations. In the dedicated convoy environment, these modifications are generally stable and visible to all participants, provided they use assets that already exist within the shared data manifests.

## Technical Tool Preparation

The primary game database files (`.sii`) use a binary encryption that prevents direct text editing. You must first decrypt these files using community-validated technical utilities.

<Steps>
  <Step title="Acquire Decryption Utilities">
    Download a reputable decryption tool such as **SII\_Decrypt**.
  </Step>

  <Step title="Locate Your Profile Data">
    Navigate to your local game directory: `Documents/Euro Truck Simulator 2/profiles/[ProfileID]/save/quicksave/`.
  </Step>

  <Step title="Initialize Decryption">
    Drag your `game.sii` file onto the decrypter executable. The file will transition to a plain-text format that can be parsed by any technical editor (e.g., Notepad++).
  </Step>
</Steps>

## Executing Strategic Edits

Once the file is human-readable, you can search for and modify specific mechanical parameters.

<Tabs>
  <Tab title="Mechanical Swapping">
    Locate the `engine` or `gearbox` data paths. You can replace the technical string of your current part with the path of a part from a different manufacturer (e.g., swapping a Renault engine for a Scania DC16 engine) to improve performance or alter the audio profile of your truck.
  </Tab>

  <Tab title="Weight & Cargo Logic">
    Search for `cargo_mass` within your active job entry. By reducing this value, you can transport "Heavy Cargo" loads with increased acceleration, or increase it to create extreme pulling challenges for community events.
  </Tab>
</Tabs>

<Important>
  ### Convoy Visibility Logic

  If you use an edited truck that refers to assets from a modification that the server does not have registered (or that your fellow drivers lack), other participants will observe your vehicle as a generic fallback "Placeholder" truck. To ensure your custom rig is visible to your entire convoy, always use **Base Game** or **Official DLC** technical paths for your save edits.
