Tunercats OBD2 is much like the OBD1 version. I have never used it with a roadrunner so I don't really know what functionality that adds. I don't think it logs does it?
In playing with EFILive demos it sure does have some pretty cool features. Their V2 interface is very nice. Personally if I were going to buy something to use in a professional environment where it was going to generate cash I think I might lean towards EFILive like Dave W did.
