Hi mentors,

I have a little question below:


I bought a used 2018 BMW G30 520i that had tuned ecu to get more power.
And I want to buy another 2018 BMW G30 520i now.
Could I use ecu tool(master version) to read 2018 BMW G30 520i ecu file that had tuned and write to another 2018 BMW G30 520i ?

Thanks

Its not that easy!

1. This car is VR read. So you can not read by OBD until you patch it by opening ECU.
2. Other car will most probably not have same SW version! So file is not compatible.

But if you get the file.... and its same HW SW and everything.... than it works (on this car)
