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.

You just have to figure out your com ports so your laptop connects. The first time can be really annoying. Yes I would imagine it would affect performance but an F series JB4 coming an option to select n54 doesn't make sense. I'm sure he just didn't setup the app right

Where can I find the best settings and learn more about playing with the settings on the JB4? I have the user guide but it's doesn't say much about user amendments.
Cheers in advance
You really don't have to mess with user adjustments if you don't want to. Map 1, log and your good to go! You won't need to mess with much until you start pushing the limits, on the M2 the first weak link is the high pressure fuel pump. So e85 mixes and map 2 exploration will usually call for changes to your FOL setting

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

M2 definitely need different User Adjustments than regular N55
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.

That sounds more like an installation quark. Something to do with the battery. You can reset your battery and DME by unhooking it for an hour or so.

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.

Yeah I'm really excited for bootmod3! How's it going so far?

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

Look into the F series Mafless trick. You unplug the maf on the air box and the car runs off the wideband o2 readings. Much smoother!

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!

The Support; the Team involved; Development and Features coming into Bootmod3 is just AMAZING!
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).

SOrry to be a pain, could you explain what you mean?
Literally unlug the MAF, the whole thing or what? Just leave it tied to the side?
I can run map 2 with my set up right from my understanding? Where's the m2 JB4 thread?
No problem. With JB4 only you can simply unplug the MAF. It's an early F series trick that smooths everything out. Only with JB4 though.

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

Good afternoon guys, does the M2 have a wide-band sensor that can be logged to tuning?
I taking delivery of my car this week and just doing some research before hand.

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.

OH wow !! that is great new. (not it wasn't running off the wideband alone).
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)

The MAF part? Or do you think there isn't an oxygen sensor relaying information in the same fashion? It is wideband. Or just are you referring to Terry's suggestion When he doesn't want to fix something lol

It's wideband and you are right. Not really sure what he's referring to. Multiple companies offer speed density flash tunes now.

Yes the MAF part. With the stock N55 ROM logic the MAF plays a role in changes in fueling along with some other air calculation checks. It's mostly used as sanity checking in those moments but can definitely influence smoothness of the car.

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)

It drove me nuts that I never got a reasonable response from terry regarding details like this. He explains the MAF being used during low throttle/cruising/for emissions which are all important. I believe it's being used as a band aide for his intake vs a good solution.

The fail safe question is one I've had for a long time. Glad to see it here.
