Hello everyone. I have a doubt

Model: Porsche Boxster 986
Motor capacity: 2.5
Production year: 1999

ECU type and number: 5.2.2
Memories of ECU: 24c04, cc460

I would like to know if I can copy my current memory 24c04 to a new dme and use the two or if each time the car starts a part of the eprom 24c04 is written varying the information. I would also like to know if the cc460 bosch that is where the engine map is located has the VIN of the previous car staked or if it can start without problems.

Thanks. all
