Map 2 on 93 worked best for me.. 11.6@118 with very little timing being pulled. I would still data log it as every car and location is different. Elevation and weather changes everything
It picked up 3 tenths with E30,but I can’t get it to hook. On the top end it gained 5mph. Felt like a whole different car in 3rd and 4th gear Last edited by Value; 03-10-2023 at 07:14 AM.. |

I like a little safety blanket and tend to run a map one step lower than recommended for my fuel. With map 4 having an E30 recommendation it makes me believe it’s more aggressive than map 2. And with map 2 including 93 in its recommendation I would likely not run it if I only had 91, even though 91 is mentioned in map 2. Bottom line is there’s not a night and day difference between the maps that I’ve noticed, and if I had it to do over again I may have just stuck with the JB+ as it performed GREAT for the price. |

Would you say the above is safe enough? |

I never moved the JB+ from the default position. I would try that first and see if you're happy. If you have 93 (U.S.) then turning it up a little should be fine, but I've read where some people didn't think it ran as smooth...but I have no idea what other conditions may have been present.

I believe the stock position for the JB+ is 3pm which is circa 4psi.
I’m looking to reduce boost to the 1pm position 3ish PSI. So with 93 fuel it should be safe enough? |

I believe Burger Tuning declares the JB+ safe in default position with 91, so no doubt it should be safe turned down with higher octane.

On one hand it would seem to be map 4 as it limits the turbo to 20 psi, which is about the max you'll see from the factory. However, it may try to target 20 psi when the ECU is only requesting 12 psi, which is a significant jump. On the other hand, map 1 is a fairly modest 3 psi increase and is the suggested map for running 91. However, you can see max boost of 23 psi, which seems pretty high for 91. I'm currently running map 2 with E30 (E85 & 93) and it punches like a pissed-off Mike Tyson! However, I seldom go WOT, so hopefully my turbo and trans will last a long while. The only negatives I've found with my setup is the throttle will rapidly close if I forget to turn TC off (short press), even with a 265 square setup, and I think I'm getting a little too much torque reduction from the xHP Flashtool on upshifts when WOT in lower gears. But if this helps prolong the transmission, and I seldom go WOT, then I guess it's ok. I've noticed if actually doing a Launch Control that xHP knows what I'm doing and doesn't interfere with the Torque Reduction setting, so a 0-60...70...80 run is almost nauseating. |

late to the party here- Does below statement mean I can run just 93 with map4?
Map4: Absolute target map with peak target of 20psi (93+ and/or 30% E85, EWG connector suggested) |

My recommendation for 93 alone is Map 1. I like a little safety buffer. I’m running Map 2 with e30. When I can find only 91 or 93 I switch to Map 1 and sometimes Map 0. |

So I have a 2023 M240i Xdrive with AA Catted downpipe, MST Cold air & JB4 with EWG hooked up. I ve been running Map 3 with 93 Octane and my question is how accurate is the Boost Gauge from the JB4 app. There have been multiple times I hit 30+ lbs of Boost, is the accurate?
