Are there any disadvantages using 98 Ron petrol {or the 100 Ron one} with the original ecu map/bin {which is design for use with 95 Ron petrol}?

Well, I have a 4-maps eprom switch in my car and two of the maps are for 95 Ron, and the other two probably for 98 Ron.

My concern is for the engine heat {if increases} using 100 Ron {or 98 Ron} fuel with the first two maps, for 95 Ron.

no worries as ! you have a knock sensor and if you put bad fuel in it it will take the spark advance back and will not allow high boost

that's in case of 'bad' fuel, presuming my knock sensor does its 'job'.
I concern about 'better' fuel {100 Ron} with the oem eprom.
