Cheers for the replies guys , I emailed MHD a few days back and they just replied saying the same thing. I think I’ll probably run the 91 oct map and use bp98 whenever I can, that way for road trips I can drop to 95ron and not worry

Hi guys, first time poster My 335i (N54) is FBO and I’m going to be flashing MHD stage 2 in the next few weeks. Despite looking at videos and trawling forums I’m still confused as to what fuel map I should choose. My understanding is that if I run 95 or 98 pump gas, I should select the 93RON map. Could anyone with some experience please help? Attached a picture of the car cause I’m new lol. Currently running a custom tune from Peter at Superchips/Alientech Cheers!
