Always use 95RON as recommended but forgot and put Optimax 98RON in recently. After that the idle wouldn't settle down and stayed at 1500+ (pain to drive). This lasted a few days then I topped up with 95 and went for a blast and seems OK now. I thought the ECU takes care of this and specialists I spoke with said nothing to do with fuel (as the ECU takes care of things!)but I can't think of anything else that's changed and the 98 if nothing else should just give it a clean (apart from the suggested power increase)

Out of interest, any thoughts or comments? scratchchin

Only that I only use 98 or 100RON in my F512M and she runs perfectly. No idea if the ecu is particularly different to a TR's or what the reason for your high idle may be. There are some more technically capable chaps in the TR section on Ferrari Chat who will probably be able to help.
