Ensure you are logged in as an Administrator.

Enter your customer ID and password provided by EVC. The software will "phone home" to register your hardware ID.

Run the WinOLS_4.7_Setup.exe . If you are a licensed user, download this directly from the EVC website to ensure you have the latest build.

Choose your installation path. It is usually best to stick with the default C:\Program Files (x86)\EVC\WinOLS .

Ensure "Plugins" and "Checksums" are checked if prompted. These are vital for correcting file errors after you modify maps.

WinOLS remains the industry standard for professional engine remapping and ECU file editing. With the release of version 4.7, EVC has introduced several stability improvements and feature updates that make it essential for modern tuners.
