You can tune an ecm just fine using a DVM, as your only source of info.
Granted it takes alot longer.
Logging is just icing on the cake.
A DVM, Scanner, Dataloging are just the levels of ecm monitoring.
  All reguire some sort of performance measuring, when tuning for max HP.
Matter of fact, I'd almost recommend to start tuning, using only a DVM.
Once you have the basics down, then you can really "see" what your doing.
