I am trying to understand more about ECUs.

If I flash a ECU that is same model / stage number such as Bosch MED17.5.5 03C906027BA 0261S05812 but with a different software version such as 515355 to 528374... What is the expected effect?

The file being flashed is from the same year / model / engine car.

Thanks... Next question if you have time please...

If my car has no OBD read option available... Only virtual read... How can I know what is the software version in the ECU? Only bench read? Or other way possible to know software version?

Try id function with kess

ID shows this

506733

9660 I believe is software version? But it does not show what software it is?

Ecu Prod: 03C906027BA (visible on ECU cover)
Ecu Stage Number: 0261S05812 (visible on ECU cover)
Software: ???
Software Version: 9660 (from ID)
