Divide & Conquer
Find the change that caused the problem. · Binary Change Analyzer
Compare a known-good file with a modified file that causes a problem. EasyTunePro progressively divides the differences into smaller test groups, generating test files that help isolate the change responsible for the issue.
Why do I need to log in?
- A diagnosis can take hours or days between tests. Your progress is saved to your account so you can close the page and continue later.
- You can resume from any device, for example from your phone while you are at the vehicle.
- Your original file, modified file and every test file are stored privately. Only your account can open or download them.
- Each test file, result and note stays linked to the exact step that produced it, so the history is never lost.

Instead of manually testing hundreds or thousands of differences, Divide & Conquer reduces the search space after each real-world test.
How it works
- Upload the known-good file.
- Upload the modified file that causes the problem.
- EasyTunePro identifies all differences.
- We generate a test file containing a controlled subset of those changes.
- Test the file on the vehicle/device.
- Tell us whether the problem is present.
- EasyTunePro automatically determines the next test.
- Repeat until the problematic change or minimal suspect set is isolated.
You can close EasyTunePro between tests. Your diagnosis progress is saved automatically and can be resumed later.
The problem is not always a single byte. If changes only fail together, the tool detects the interaction and keeps narrowing down the minimal set of changes involved.
