What I have come across before is that it does communicate with other ECU's (as we all know) and takes what other units tell it into consideration... ie, for example I took a BCM from 2006 vectra which does support the 'sports cdc' function and fitted it to an older car, that option then became 'not available' so it has other units telling it what its allowed to enable... take that into consideration when attemption to fit newer modules to older cars..
