Running 100 Octane
So on my 435 xdrive I currently have ER downpipe, AFE sealed intake, and jb4 (map5). I was looking to run 100 octane as there is a pump near my house. I know map 7 is meant for race gas features but then what is the difference if I run it on map 5 which is the autotune feature.
Anyone know the difference or any information they can pass to my direction. First hand experience maybe? Thanks again! |

On 100oct, map5 should autotune up to close to map7, but map5 on my M235i doesn't seem to do as well as it did on my old FBO N54.
I run 100oct full time, and I prefer map7. |

Map 5 will auto tune to a happy medium for your modifications and octane. It will take some time to adapt.
Map 7 is a straight shot to 18.5 PSI. It could be theoretically too aggressive as it's not a one map fits all. You should datalog. Map 5: Autotuning map, absolute target of 11-17psi based on octane and conditions. Map 6: User definable absolute target map. Suggested for troubleshooting by professionals only. Map 7: Race gas map. Absolute target of 18.5psi. Requires straight unleaded race gas. |

Map 7 has preset target that the Jb4 will target no matter what mods you have. If you are going to use map 7 it is strongly recommended that you datalog and post it on forums or Burger Tuning technical support
