I am now making a conversion of E93 325i N53 engine to 330i. I have successfully made all those steps: 
-changed the intake manifold for 3 stage
-made a full backup from E60 530i N53 car engine ECU
-loaded this full backup to actual E93 325i with modified ISN to match ISN record in CAS unit
-with ista/p I choose DME unit replace, it counted all necesary steps as SW update, coding of the unit, delete adaptations and equipment variants and even offered me writting new injector correction values. All those steps ended successfully

Only problem I have is this error message and engine is after start in limp mode:
2FA4 incorrect data record 

I read few threads about this error on this forum and on the internet and the problem should be in CLASS_PWR value in CAS unit coding. This value I found there actual is keine - 00 but if I change it to wert2 - 02 (same as in DME unit now) it throws error while coding CAS unit.




So I am asking anybody who is able to help me to edit CAS EEPROM to change CLASS_PWR value from 00 to 02. CAS is CAS3 version. I am attaching all files I have. DME full backup and CAS unit readed EEPROM.

Thanks is advance!
