Were you able to pull the ISN from the dump? You need(ed) ISN for emulator I presume?
Bosch 484 DME (m60b..) has a EWS2 Immobiliser system and the part of it uses 27C512 (not 100% sure) so in reality dump from another 484 DME will not help you.
Since I am currenlty working on getting a 484 DME to run I'll leave a brief description what I have done so far. Maybe it will help somebody with the same problem.
What I have learned:
* This DME has part of it's immobiliser system info written into the beginning of 27C512 and it offsets maps so regular performance chips will not work.
* Immo emulator seems to be the only reasonable way to bypass EWS2.
* Chinese emulators are cheap (7€ in Aliexpress) but seems that they are difficult to get working. I have ordered them too so I can't speak from experience right now.
* 484 DME uses K-line communication (pin 88; Pin 20 in "pacman" connector)
* Simple FT232BL breakout board can be used as K-line interface, INPA also works well with it. Chinese VAG-com cables are based on that chip too.
Reading ISN:
I used INPA and DME running on my workbench(+12 to pin 26; pin54 - ground to Pin55). For communication interface I used FT232BL breakout board and a simple K-line level converter/amplifier circuit connected to pin 88 on DME(Rx;Tx connected to FT232 Rx;Tx). Install INPA, preferably INPA Pack 2016 V1.2a (many thanks to 328 Power 04 !) Start up INPA and if you have connected all the wires correctly you should able to connect to DME - Shift+F7 (Engine) -> 8 Cylinder -> DME 3.3 for M60 (press enter) -> F3 -> ISN for EWS.
