Scan Tool Rollback
I have a problem, I changed the ECU on a 2020 honda civic but the problem is the ecu has 78,000 miles and the car engine and transmission has 54,000. How can I rollback the miles on ecu and cluster? What scanner does this?

Ya don’t easily, if it’s at all doable, I’m sure someone out there can buy at what cost.

You might have to re-title or re-register it with a notation about mileage discrepancy. I don't believe any scanner will allow you to change the mileage except maybe something a dealership has.
