Scrambler
Protect a tuned file from being copied or resold.
Upload the original and the modified file. The engine obfuscates the calibration area so the file works on the car but cannot be read back into WinOLS as a clean project.
Accepts: .bin (original + modified, up to 16 MB each) · Free
Upload the flash read on the start page; the file page shows the button when the tool takes your ECU.
