that exhaust smell you talk, that happens to me too...
I think that smell is the result of the hot exhaust gases burning the stuff that comes down from the egr pipe which is connected just below the catalytic converter...
with eco driving it doesn't get hot enough, but when pulling the revs to the top give that extra temperature...
Because this smell only happens when we make some miles without high revs...
If we rev it hard 2 or 3 pulls the smell stops, so no more stuff to burn...
But this is me guessing... Many R18 owners feel the same smell, only drivers that don't, are the ones with more sporty driving..
