JB4 Question 2022 M40i
Hello forum,
Have a question about a JB4 since these motors can't be tuned "yet". Is it really as simple as a plug and play or does it need to be professionally tuned and installed? Currently have a catted DP and MST Intake and the car moves, but always welcome faster. Thanks. |

No first hand experience with JB4, so can't comment. but from what I know, it's a plug and play device, as long as you're comfortable around cars.
On another note, would you have any videos of how the intake and the DP sound on the car? |

For 93 oct it's pretty much established you can run the preset map 2 without issue. If you want to play with ethanol you will have to look at logs etc to optimize it…. |

Just installed a JB4 a couple weeks ago on my 2021. Get the Bluetooth add-on, trust me. The JB4 app does cost around $27 if I remember correctly. Install it yourself, run a couple different maps (I've been running Map 3 with the EWG connection), and see how you like it. Considering we have no true tuning options yet, I've been quite pleased thus far.
Installation is stupid simple, just watch their videos first. You will probably want to remove the MST shields to reach the EWG connection, it's the trickiest connection to make, but not hard. Also, don't even mess with dropping the panel under your steering wheel when running the OBDII cable. The hole through the firewall is easily accessible without doing that. If you put it in the recommended area, don't put it up next to the firewall, as it can impede your windshield wipers. Also, how do you like the MST intake? I have one, too, just not for the X3 lolol. They sent me a B58 intake, with some other model's covers... waiting on them to send me the correct ones. I do really like the additional woosh/whistle. |

If you can find a place that has done them before, I'd say $75 is probably reasonable. |

You used to be able to send your log files into BMS & they would tell you what if any settings needed to be changed & give you the corrected settings. FWIW to anyone: If you can read, look at pictures & follow instructions it should not take over an hour to install the system.
