No idea, ask Jano. I know nothing about the ECU electrickery.
My old TS was mapped to run on 98. It certainly gave more BHP on the rolling road than standard 95.
which is why its not worth spending money on increased RON fuel, unless you have shares in BP/Shell etc
no matter what anyone tells you - you are wasting your time on an Alfa.
I will argue that shell V-power is great just for it's cleaning additive anyway.
