Very noob question here.  I have two ECU's, one is a 8N0906018BB from a 2003 Audi TT 225HP M/T, the other is a 8N0906018CJ from a 2004 Audi TT 225HP M/T.
Both are the BEA engine code.
My question is can I read the file out of one ECU and flash it into the other?  I don't know what is the difference between them. Same engine code only a year apart.
My car is actually a 2001 TT and I bought these for wideband O2 conversion.

All the 8N 29F800 ecu's have the same hardware.
