The -E-ngine -C-ontrol -M-odule, or ECM recorded the vehicle mileage along with the odometer. The EMC mileage can be read by a scan tool at most dealerships or repair shops with the proper equipment. It is possible for the two mileages to differ slightly, but a large variance may indicate a faulty odometer, or possibly odometer tampering.

What is deffrent between mileage and ECM mileage in semi truck?
ECM mileage is based on the number of transmission output shaft rotations, and is calculated along with the programmed rear end gear ratio, transmission gear ratios, and revolutions per mile for the programmed tire size. Actual mileage will vary according to tire wear... as your tires wear down, the actual mileage you travel will decrease.
Will changing the ECM affect the mileage on a 2005 Chevy Silverado?
Unless it's an all-out racing chip, which I doubt, I would think your driving habits would affect gas mileage much more than just changing the ECM chip.

Does a knock sensor ECM error mean that sensor is bad or that the sensor is just reporting a knock in the engine?
The sensor is bad. A properly-functioning knock sensor allows the ECM to advance timing until it senses a knock. It then retards timing until the knock just barely goes away allowing for optimal gas mileage.
What does ecm mean on a car?

What does flashing the system mean in auto mechanics?
re-programming the ECM (Engine Control Module)
Will removing the ecm fuse cause problems?
Since the ecm (engine control module) is necessary to run a modern car, the simple answer is: Yes. Not having the year, make or model, exactly what the ecm controls in this instance is unknown. But regardless, the vehicle will not operate without it. Also, removing the fuse and therefore removing power from the ECM may cause all the learned engine parameters revert to their initial state and your engine may not run as well or get as good mileage until the ECM relearns new parameters.
