Here we have 2 ecus, A 7D and a Z4,which is which ?







Also, as they look bloody identical, how do you tell which from which ?

what part contains the mapping for the fuel they use ?

i dont intend to map these etc etc but am just curious to know which part in their standard from contains the mapping.

cheers.....

 

I dont know much but my Z4 has the extra socket for another chip like the top pic so Id guess at the z4 being the top one....could be wrong though.

 

Hmm, the one i have with the extra socket, top pic, was the 7D uk ecu

This is what i mean, how do we tell them difference by looking ???

 

Just found this bit of info


Just keep an eye out for an ECU with a socket already in it, my Z5 had a socket and I'm told the following model numbers also have sockets pre built so you literally just have to drop the chip in (no soldering):
V7, 6D, 7D or 7K

 

Normally the UK ECU's already have the 28pin socket fitted whereas the JDM variant requires one fitting (some JDM ecu's have had sockets fitted which can be identified by the soldering) - the easiest way to tell is to 'dump' the map via the select port and compare the map to a true Z4 map - but this requires software etc
