Visualizer live connector - OLS1018

The OLS1018 is a software plugin designed to integrate with WinOLS, a powerful application for editing engine control unit (ECU) data. Its primary function is to act as a "live connector" for the WinOLS Visualizer tool. This allows the Visualizer to connect to and display real-time data from third-party programs.

The cost of this plugin is valued at 3 checksum points. In the EVC ecosystem (the company that developed WinOLS), checksum points are a type of credit that users can purchase and redeem for various plugins and software features.

The "Visualizer Live Connector" Option

This is the key feature of the OLS1018 plugin. It is a dynamic link library (DLL) that establishes a communication bridge between the WinOLS Visualizer and other external applications.

Main Features:

Connection to Third-Party Programs: Allows external diagnostic or data-logging tools to send real-time information directly to the WinOLS Visualizer. This is essential for chiptuning professionals, as they can observe the engine's behavior in real time on an ECU map while the data is being recorded.

CSV File Import: In addition to the live connection, this plugin enables drag-and-drop functionality for comma-separated values ​​(CSV) files directly into the Visualizer window. This makes it easy to analyze previously recorded data without the need for a live connection.

API for Developers:

EVC, the company behind WinOLS, provides a free Application Programming Interface (API) so that other software developers can make their programs compatible with the WinOLS Visualizer. The API is available in the following programming languages:

• C#
• C++

This fosters an ecosystem of compatible tools, allowing greater flexibility for users.

Integration with Third-Party Programs

The purpose of OLS1018 is to enable collaboration between WinOLS and other tools. Currently, the following programs are supported:

• VehiCAL: Vehicle data logging and analysis software. With the OLS1018, data recorded by VehiCAL can be displayed in real time on the ECU maps in WinOLS.
• ismFlash: A tool for reading and writing vehicle control unit data. As with VehiCAL, the OLS1018 allows ismFlash log data to be displayed in the Visualizer.

Important: For this integration to work, not only is the OLS1018 plugin required, but third-party programs (such as VehiCAL or ismFlash) must also be prepared and configured to establish this connection.

Version Details and System Requirements

Software Compatibility:

• WinOLS5: All functionality and future updates of the OLS1018 plugin are designed exclusively for WinOLS5.
• WinOLS4: Support and updates for WinOLS4 versions ceased on December 31, 2022. Therefore, WinOLS5 is required to use this plugin.

Version History:

Date	Version	Guy	Change
01.02.2023	1.007	New	The plugin has been renamed. Users are instructed to contact EVC if they encounter any issues.
01/31/2023	1,000	New	First functional version released to the public.
01/30/2023	0	New	Preliminary version, not yet ready for use.

This history shows the recent development of the plugin, indicating that it is a relatively new product and under active development.

The Concept of "Checksum" in WinOLS

The term checksum is crucial in the context of ECU modification.

• What is a Checksum? A checksum is a value calculated from a block of digital data. The ECU uses this value to verify the integrity of its map data. If even a single bit of the map data is modified, the calculated checksum will not match the stored checksum, typically resulting in the vehicle not starting as a safety measure.
• Checksum Correction: When a chiptuning professional modifies a map in WinOLS, it is absolutely necessary to recalculate the checksum to match the new data. WinOLS can perform this correction automatically if the appropriate checksum plugin is available for the ECU in question.
• Checksum Points: These are EVC's virtual currency for purchasing these checksum correction plugins or, as in the case of the OLS1018, other types of functional add-ons. The fact that the OLS1018 is worth 3 points indicates its level of complexity and value within EVC's product offering.

In short, the OLS1018 is a specialized tool for chiptuning professionals using WinOLS5. Its main value lies in the ability to display real-time data from external tools directly over the ECU maps, allowing for much more precise and dynamic analysis and calibration.
