Scania Sops File Parameter List
The Scania On-board Product Specification (SOPS) file contains vital vehicle configuration data, enabling adjustments to parameters such as NOx control, AdBlue, and maximum speed limits. Modifying these files requires extracting them via Scania SDP3, followed by decryption into XML format for editing. View the full, detailed parameter list in this PDF from BalticDiag.

A Scania SOPS (Scania On-board Product Specification) file is essentially the "digital DNA" of a Scania vehicle. It contains every configuration detail, from the number of axles to the specific software version of the engine. This file is stored in two key control units: the Coordinator (COO) and the Instrument Cluster (ICL). Common SOPS Parameters
The SOPS file contains hundreds of parameters (often identified by FPC IDs) that define how the truck operates. Technicians frequently modify these to customize performance or enable/disable specific features.
Understanding the Scania SOPS File Parameter List A Scania SOPS (Scania On-board Product Specification) file is essentially the "digital DNA" of a Scania vehicle. It contains the complete configuration of every system, from the engine's torque limits to the behavior of the exterior lighting. Technicians use the Scania SOPS File Parameter List to identify which vehicle features can be modified, added, or deactivated to suit specific operational needs. What is a SOPS File?
The SOPS file is a stored configuration typically located in two control units: the Coordinator (COO) and the Instrument Cluster (ICL). It acts as a master blueprint that tells the vehicle's electronic control units (ECUs) which hardware is present and how it should behave.
Technicians often need to edit these files for "conversions," such as changing speed limits, adjusting fuel tank capacities in the display, or disabling specific sensors for diagnostic purposes. Detailed Scania SOPS Parameter List
The list of parameters is extensive, often exceeding 300 individual entries. These are categorized by the vehicle system they influence. Below are some of the most commonly modified parameters found in Scania SOPS files: 1. Engine and Performance
Engine Type & Revs: Defines the core engine configuration and operating RPM ranges.
Speed Limits: Includes SpeedLimit EOL and Speed limit second, which govern the maximum legal and operational speeds of the truck.
Idle Speeds: Low idle speed and High idle speed offset settings for engine warmup or PTO operation. Scania Sops File Parameter List
Acceleration Limiters: Max acceleration at 0 km/h and 90 km/h to improve fuel efficiency or safety. 2. Emissions and Exhaust CONV:01 - Scania Technical Information Library
The Scania SOPS (On-board Product Specification) file is a vital configuration file used to define the specific features and hardware setup of a Scania vehicle. It is stored in both the Coordinator (COO) and the Instrument Cluster (ICL).
Editing these files allows you to "write" or modify hundreds of vehicle parameters—such as AdBlue settings, EGR, and speed limits—without needing to request a conversion from Scania headquarters. 🛠️ The "Write" Process: How it Works
To modify or "write" new parameters to a vehicle, you typically follow a specific technical workflow using an Encryptor/Decryptor tool alongside Scania SDP3 (Diagnos & Programmer) software:
Export: Use SDP3 to download the current SOPS file from the truck.
Decrypt: Use a SOPS Encryptor/Decryptor to convert the binary SOPS file into an editable XML format.
Edit: Open the XML file in a text or dedicated XML editor to change parameter values.
Encrypt: Convert the modified XML file back into the encrypted SOPS format.
Import: Use SDP3 to upload ("write") the new SOPS file back to the vehicle's control units. 📋 Common Parameters You Can "Write" change_log
You can modify over 300 parameters. Common examples found in the SOPS Parameter List include:
Engine & Emissions: AdBlue/SCR system, EGR control, NOx control, and white smoke limiter.
Performance: Speed limits (SpeedLimit EOL), gear ratio, and torque reduction.
Comfort & Safety: AC settings, fog lamps, seat belt reminders, and central locking.
Transmission: Gearbox type, PTO (Power Take-Off) control, and retarder settings. ⚠️ Important Considerations
Redundancy: Because the file is stored in two locations (COO and ICL), both must match for the vehicle to function correctly.
Risk: Writing incorrect parameters can cause system failures or fault codes in SDP3.
Tools: Professional kits often include the XML Editor and Decryptor software needed for this specific "write" feature.
The Scania SOPS (Scania On-board Product Specification) file is a vehicle configuration format used to store parameters across control units like the Coordinator (COO) and Instrument Cluster (ICL). Technicians use these files to modify vehicle behaviors, such as speed limits, emission controls, or fuel tank configurations. Core Parameter Groups this file is useless.

Validation checklist before flashing to vehicle
- [ ] Original SOPS backup saved and hashed
- [ ] ECU SW and HW versions recorded
- [ ] Checksum validated
- [ ] CAN IDs validated (no conflicts)

Method 1: Using SDP3 (Official)
- Connect to the vehicle.
- Navigate to Vehicle – SOPs – Take SOPs.
- Save the file to your hard drive.
- Use the SOPs Viewer tool inside SDP3 (under Extras) to print or export the list to PDF/CSV.
1. Introduction to SOPS Files
SOPS stands for "Seat of Pants". In the context of Scania ECU programming, a SOPS file is a calibration file used by the Engine Control Unit (ECU) to determine fuel quantity, injection timing, and pressure based on driver demand and engine load.
Unlike standard OBD tuning, Scania uses a complex architecture where the ECU calculates fuel delivery based on a "Desired Torque" value. The SOPS file contains the maps that translate this torque demand into physical injection parameters (mg/stroke).
5. Value for Money
Rating: ★★★★☆ (4/5)
- For Professionals: It is excellent value. It saves dozens of hours of reverse engineering. For a tuning shop, paying for a verified Sops list allows them to offer services (like removing speed limiters or custom gearbox tuning) that generic tools cannot touch.
- For DIY/Amateurs: It has zero value and poses high risk. Without the hardware (e.g., KessV2, K-TAG) and the knowledge to use it, this file is useless.
