Hello !
Does anyone know of a tune company that works with 95 Octane? I'm moving to a country where that is available at the gas pump. will JB4 autotune option really work?
I'm currently running 93 AKI in the US.
found out the country where I'm moving to use 95 RON which actually is equal to 91 AKI which is even more annoying.
My car is 2014 535i xDrive.
Thank you

Your built-in octane map already includes 91 AKI, as CA, and probably others, doesn't use 93. If you check your owner's manual, you can probably use 89.
