[mafia666]

hi. I want to use second hand cem from donor car. inside cem there is 29f400 and inside engine ecu 95p08. if i replace flash only, will it work, or do i need to transfer syncro data and program keys again? can anybody give a advice? files from both cem units and engine ecu are attached.

swap intel flash chip

thanks mate. i tried it. owner of the car called this morning and was whining about it: only check engine comes on, no ignition, starter is cranking and bla bla bla. i will double check soldering today. are you 100 % sure it's enough to move only intel flash?

In flash are the keys stored and the immodata.

What is the problem on the car why you changed the cem?
