WinOLS 4.7!

WinOLS is a popular software tool used for modifying and optimizing engine control unit (ECU) files, particularly for diesel engines. Here are some interesting features of WinOLS 4.7:

Feature: Automatic Table Detection (ATD)

One of the standout features of WinOLS 4.7 is its Automatic Table Detection (ATD) capability. This feature allows users to quickly identify and decode complex ECU tables, making it easier to modify and optimize engine parameters.

What does ATD do?

With ATD, WinOLS 4.7 can automatically:

1. Detect table structures: Identify the layout and organization of data tables within the ECU file.
2. Recognize data types: Determine the data type (e.g., integer, float, etc.) and scaling of each table column.
3. Decode table contents: Translate the raw data into human-readable values, making it easier to understand and modify.

Benefits of ATD

The Automatic Table Detection feature offers several benefits:

• Time-saving: Reduces the time spent on manual analysis and decoding of ECU tables.
• Increased accuracy: Minimizes the risk of errors and misinterpretation of data.
• Improved productivity: Enables users to focus on optimizing engine performance and calibration.

Other notable features of WinOLS 4.7

In addition to ATD, WinOLS 4.7 offers a range of other features, including:

• Support for various ECU types: Compatibility with a wide range of ECU manufacturers and file formats.
• Flexible data editing: Allows users to modify ECU data, including tables, curves, and text.
• Data comparison and analysis: Enables users to compare and analyze different ECU files and versions.

Overall, WinOLS 4.7 is a powerful tool for ECU calibration and optimization, and its Automatic Table Detection feature makes it an attractive choice for professionals working with diesel engine calibration.

Supported Operations

• Read / Write via BDM, JTAG, OBD, K‑Line, CAN, and boot mode
• File formats: .bin, .hex, .s19, .ori, .dam, .ols, and more
• Data logging and dyno integration (select plugins)

3. Checksum Correction (Checksum Plugin)

Modern ECUs run a security check called a checksum. If you edit a map but don't correct the checksum, the ECU will detect corruption and throw a "Checksum Error," bricking the car or putting it into limp mode. WinOLS 4.7 includes an automated checksum plugin that instantly recalculates and fixes all necessary checksums after every edit. Without this feature, tuning would be impossible.
