Yeah, if you have nothing, it's great.
I made a mistake here (I confused another scanner program error). Winaldl's retard does *no* conversion at all. It shows the raw data as degrees retard. Just divide the number shown by 5.6 and you'll have the correct degrees of retard.
IAT/MAT is still wrong, period.
Again, if you have nothing it's worth using. The adapter cable is very simple too.
