Your XDF file size matches what I have here. What size of engine are you needing? Is it really an 8.1 liter engine that is what you are installing in a vehicle? I'm thinking there may be something already wrong with the BIN you posted above. Not that it was your fault but that somebody had bodged up by using the wrong XDF with it before you got it.

If it is a different engine size that you need, this BIN will require a segment swap.
