when read or writing these via obd the tuning tool knows which is master/slave but to do it via boot mode how to tell your reading the master so you know when writing back your writing master or slave

many thanks.

surely someone must know or when doing via boot mode do i just read either of them and write modded flash to both presuming the car defines which is master ecu and therefore both ecu are identical.

i did try reading obd but car ignition times out before end of read and many people talk about high risk of bricking when done via obd
