I obvously know what RON rating it says on the petrol station, for example here in Moscow for DD on all my turbo cars I use RON 98, however, unfortunately, not always this fuel is actually RON 98. I mean it could easily be bad quality 98 or even smaller RON rating fuel.
I will try to explain why I ask this question. When I do some upgrade to my Suabru I go to my tuner and we will map the car on a specific fuel that I will in most cases use. If later I use even another petrol company, fuel can be different and this could lead to richer/leaner fuel/air mixtures and potentialy cause problems. So when I purchase the ESS mapping kit and send you my original map, will you be able to see what fuel I use so the map is 'unique' to this fuel, or the map is universal for all X5/6Ms and the ECU itself alters engines work after the re-map? I hope I have explained my worry here
Also, do ESS take into consideration exactly what aftermarket parts are installed, for example SS de-cat with Akrapovic EVO exhaust, or SS x-pipe with Eisenmann muffler and K&N filters, or you just look at whether the car is de-cat or not?
thx beforehand for explanation
