How to Match Two Projects in WinOLS and Copy Data Manually

When working with ECU tuning in WinOLS, automotive enthusiasts and professionals often need to match two projects. Whether you're transferring map data, modifying control parameters, or tuning different versions of the same vehicle’s ECU, manually copying data can be essential. This guide will show you the most effective method for matching two projects in WinOLS and copying data between them.

WinOLS is a powerful tool for ECU remapping, but the process of matching two projects allows tuners to compare and adjust data between different ECUs. Whether you’re upgrading an older model to a newer calibration or copying custom settings to a different ECU, manually copying data ensures precision in your tuning process.

Step-by-Step Guide to Matching Two Projects and Copying Data Manually in WinOLS
Here’s a breakdown of how to achieve this manually:
1. Open Both Projects in WinOLS

• Open WinOLS and load both projects you need to work with. If you’re working with multiple versions of the same ECU or even different vehicles, you’ll need these files side-by-side.
• Click on the “Window” tab in the main menu and select "Tile Vertically" to see both projects next to each other. This will help you to compare maps and tables easily.

2. Identify and Compare Maps

• Start by locating the maps or tables you want to copy. Maps such as turbo boost, fuel injection, and torque limiter tables are common areas where data transfer might be needed.
• Click on the "Map List" on both projects to see which maps are available. Right-click on the maps you’re interested in to get more details.

3. Use Map Comparison to Align the Data

• Manually compare the maps between both projects. WinOLS offers a handy comparison tool that allows you to overlay the maps.
• Go to the Map Compare Mode by selecting "Tools > Compare Maps" from the menu.
• In the compare window, you’ll see how the data in both projects align. This helps in making precise decisions on which data points need to be copied.

4. Manually Copy Data from One Project to Another

• Once the maps are aligned, it’s time to copy the data manually. Highlight the values in the map of the first project, then right-click and choose “Copy.”
• Go to the corresponding map in the second project, right-click again, and choose “Paste.” Ensure you are pasting into the correct cells, so no calibration is affected improperly.

5. Ensure Consistency Across Limiters and Boost Maps

• Copying data from performance maps is only part of the process. To ensure consistency, also check and copy data from limiter maps, boost control maps, and any other essential control tables.
• This ensures that both projects are not only matched on the main performance parameters but also have consistent limiters and safety measures.

6. Verify and Save Changes

• Once you’ve copied all the necessary data, use the checksum function in WinOLS to verify that your changes won’t cause any errors.
• Finally, save the project and export the files if needed.

Pro Tips for Working with WinOLS Projects

• Backup Your Projects: Before making any changes, ensure you have a backup of both projects. This avoids any loss of critical data in case of errors.
• Use Color Coding: When comparing maps, WinOLS allows you to use color coding for easy visualization. This helps in quickly identifying discrepancies between the two projects.
• Checksum Correction: Always use the checksum correction tool to avoid issues when flashing the ECU.

Mastering the process of manually matching two projects in WinOLS can dramatically enhance your ECU tuning workflow. By following the steps outlined in this guide, you can ensure accurate and efficient data transfer between different projects, making your tuning efforts more streamlined and precise. This skill not only saves time but also minimizes errors, ensuring the best performance results for your tuning projects.

​Whether you’re a professional tuner or an automotive enthusiast, this guide provides the technical depth needed to perform this essential task while maintaining simplicity for those newer to the WinOLS software.
