Jeg ser på tuning til min 540e, har fått dette svaret med Mosselman tuning ang deres iTronic boks
«
The calibration is made on RON98 fuel, but you can run on RON95 fuel, it will adjust. It's the same running on stock, the performance BMW delivers is measured on RON98, if you fill it up with RON95 it will run just fine, but you will have (a bit) less power.
On RON98 all 30e cars we have done run between 315 and 325hp with the iTronic, so on RON 95 it will be around 300hp.»
