While some flash hardware (like Autotuner) can correct checksums during the writing process, having dedicated WinOLS plugins offers several advantages:
You do not download WinOLS checksum plugins as standalone .exe or .dll files from a standard website. Instead, you purchase the rights to a specific plugin module (e.g., OLS226 for Bosch EDC16) directly through EVC or an authorized distributor. Once purchased, the plugin license is tied to your specific WinOLS hardware dongle or customer ID. 2. Updating via the Software Interface

If you don't own the matching module, select . WinOLS will upload a compressed version of your project to the EVC server to identify exactly which plugin you need. While some flash hardware (like Autotuner) can correct
