Hi, When I had my car remapped at AMD last year (custom RR job), I'm pretty sure I had 95RON petrol in the car. But now I use BP Ultimate 97RON all the time as it is noticeably better. My question is: has my car been mapped for 95RON or doesn't it make any difference to the remapping process? Would the custom map have been the same regardless of fuel in the tank at the time? By the way, AMD never mentioned fuel type to me before or after the remap. I hope this makes sense. Cheers.
