Also is europe early s4 ecu had a 512kb memory capacity on the eeprom that runs the program for the ecu. and iirc all s4 in us use a 1024kb eeprom to run the ecu.

I can't for the life of me remember what the hell IIRC is.. I know there's a dummy list for this stuff somewhere but haven't looked yet. hah
