Visual & Technical Tuning

“Save Editing” (often called Local Modding) is a popular way to customize trucks beyond the in-game shop limits. This method allows you to swap engines, gearboxes, or trailer types across different brands. In Convoy mode, most of these changes are compatible as long as they refer to assets already present in the base game.

1. Tool Preparation

Save files in ETS2 are encrypted by default. To edit them:
  1. Download a community decryption tool like SII_Decrypt.
  2. Locate your save file: Documents/Euro Truck Simulator 2/profiles/ID/save/quicksave/game.sii.
  3. Drag game.sii onto the decrypter.

​
2. Performing Edits

Once decrypted, you can open the file with any text editor and search for key components:
  • Engine Power: Search for engine_torque and modify the value (be realistic to avoid connection kickers).
  • Parts Swapping: You can replace a Scania engine path with a Volvo engine path to create a “hybrid” truck.
