vdo use siemens vdo ecu (which the name vdo came from)
-different throttle body special to vdo model only
-use map sensor
-use crank sensor
-distributorless type ignition



mmc use mmc ecu
-similar to other 4g series throttle body type
-use maf sensor
-no crank sensor
-use distributor type ignition (or cam sensor)

which mean MMC more better then VDO, and much more space for upgrading as it similar wit 4G series...
