At the risk of provoking prj and derailing this thread further, what do you expect to gain from running an RS4 file?
Have you upgraded to alot of RS4 parts? IMO, there are far too many hardware differences for a casual switch.
I think that it's best to adapt the S4 file.
I agree, if the car does not K04's and so on it is kinda pointless to run the RS4 software.
