Here's how it should work, does it make any sense at all?

Task Levels

1. Identifies the frequency of factory quartz was cicatrized in the ECU.
2. Generate the same frequency with ultimate stability at the end of the special coaxial cable.
3. After pushing a button it modifies this frequency value with extremely high resolution.
4. Backups this frequency to a flash memory and keeps it after release of button.
5. Ready to restore factory data when both buttons is pushed simultaneously
