kiwiN54 0 Report post Posted February 5, 2021 (edited) 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!

SmackJackTheCrackerMan 54 Report post Posted February 5, 2021 Yeah, this caught me out too so I spoke to the guys at MHD who advised that the fuel we get here or what I use is BP98. They said I would have to run the 93 Oct map. Quote Share this post Link to post Share on other sites
Herbmiester 922 Report post Posted February 5, 2021 MHD uses the US reference for Octane Mon vs Ron so 93 Octane is 98 Octane for us here. Quote Share this post Link to post Share on other sites

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 Quote Share this post Link to post Share on other sites
