Hey guys quick question. I had jb4 installed by a local shop. As someone pointed out the logs show N54 instead of n55 f series. Would that effect the performance of the car when it was flashed/installed? Those logs I posted were after he installed it and he also logged for me.
I'm trying to log for myself but my laptop is giving me shit using jb4 interface. |

This is a great start, when you understand what everything does, the whole JB4 becomes much more valuable- http://f30.bimmerpost.com/forums/att...8&d=1433827618 |

Even Terry has said it over countless of emails I've exchanged with him since beginning of May. Until Terry himself grabs an M2 and dedicates more time on it, I would not recommend JB4 to anyone on that car. Paying $530 for JB4 + $140 bluetooth just to run map1 is not worth it. This is why I've joined something that will truly tune and be healthier, better, with great features proTUNING Freaks Bootmod3 Posted 2 screenshots of some of the features thus far but although N55 is still in Heavy Beta testing.

Sometimes the windows need to be reset to find their end points for the one click to work. Try rolling all the way down and holding for 3-5 seconds, then all the way up and holding for 3-5 seconds. Regardless I would detached the cable in the trunk for a couple hours for everything to reset. |

I agree that Terry needs to dedicate more time to the M2 before he sells it, it will just end up biting him long term. What user adjustment settings did he have you using and why? Didn't you have a boost problem? I really don't like how the car runs with the maf plugged in. It's great without it though |

Anyone have any experience with the bootmod 3 and should you buy both the device and the bootmod together or don't bother with buying the actual device? Thanks!

I did some datalogging last week on my V1 Beta Map and just got my V2 Beta map today. They got a M235 Track Edition in house this weekend so HUGE development going on and it will help speed up things for N55. Furthermore, it will speed up things that differ the M2, X4 M40i to the M235 to other N55's. I have, I bought both because the bm3 device will be left in the car (replaces the need of a laptop or tablet).

Unplug it and tuck under the engine cover or where ever you like. No need to change any settings. Map 2 on pump gas is a little aggressive. You'll be more prone to knock. A small mix of e85 will help bring your timing back up and your avg ign value down, but only if your HPFP can keep up. Map 2 on the M2 is equal to or greater than map 7 on a regular m235i. The factory boost targets are much higher. If you have the app let me know what your AVG ign is |

I believe so. When I used to run JB4(switched to MHD) I unplugged the MAF and ran off Wideband, at least that's how Terry explained it.

But what this means, is that the N55 in the F87 is running based on Speed density !!! with the MaF as a back check. Can someone please confirm this? Also read the engine in Direct injected, is this also true? however, is it an "open deck" block as opposed to a block with minimal coolant cavities (closed deck) |

MAF is necessary when valvetronic goes into failsafe mode. Overall these cars use a hybrid speed density setup but it's much more sophisticated than simply "unplugging the MAF"

Thanks guys I appreciate confirming my suspicion based on the original comment.
I am happy to learn this car does have a WB (which I am guessing can be logged for tuning) and that it runs SD !!! (unlike many other cars I have owned) |
