Your problem is that you had a bad reading. You should clean chip. Good before reading and read few times and save few files.
Better read with xhorse vvdi prog.
You need to fix eeprom file and write back.
Im608 in general not good with bmw.
12v not enough 14.5v try
Desoldered EEprom, wrote back original file, and then i used VVDI2 to update FEM, then after just follow instructions, and FEM worked again.
If you desolder EPROM put file original and same problem, the eeprom is dead.
Change eeprom for new one, there program original file. Then read data and check is frequency is ok.
