Hi I need to reset working hours to change powerclass, the ecu is from N54 and the car is N53. Can I just pair the DME with ISTA after working hours reset or does the ISN also need to be reset? Of course I could change the ISN in CAS to match but, would be easier just to do the changes in DME. Here is the dump from 95640.

Now I need to figure out the correct ZB number. It's a 12/07 E63 630i, so type code EA31 In asth file I found 7649264 and 7649270 for EA31. Accoring to sg file both should have hardware 7612455, but the ECU I have is hw 7616431, so can I use either one?

If I look with hw 7616431 in SG I find the following numbers 7636874, 7626374, 7621766, 7636872, 7626372, 7621760, 7621756, 7636870, 7626370. They all are under N54__6Z_MSD81_B30, so I assume I can't use those?
