Poor maintenance by past owners, running low on oil, revving while cold... all eventually can lead to this.

Had mine die on the track a few months ago, may have been a bit worn over the years from a combination of the above and finished off with hard cornering on the track.
I had been running it tuned for about 4-5 years prior, with the last 2 or so on S2+.

Awesome street cars but IMO you need an oiling upgrade for the track, or to buy a more suitable car like an M car or a Porsche...

Still in the process of getting a new engine installed...
From your perspective, how do the rod bearings or whatever seems to be ruining these engines from time to time fair during daily street use with occasional pulls?

I know that the 2011 E90 335xi has different rod bearings than the F30 335's. Also, are you aware of issues arising more w/ stage 2 as opposed to stage 1 tunes?

I don't think you have much to worry about if that's all you're doing. Remember most of us aren't the first owner of these cars by now, we don't know what happened under the previous owner(s) . Bearings might be worn and closer to failure, and the current owner is just unlucky.

Don't think there is any data out there to associate failure with tunes. How old are these cars by the time they're tuned? We're not all checking our rod bearings before we tune them.
And I think people who run tunes are more likely to drive the car hard and put extra wear on it, hence more likely to be the ones to finish off an old worn engine.

Just did a 3rd gear pull on a custom tune V0.01. Seems like the actual boost is a lot lower than target boost but WGDC% is very low? Do I have hardware problems with my car or is the initial tune just ultra safe? While i am waiting for my tuner to respond, please take a look at my log:

https://datazap.me/u/x135i2014henry/...-6-16-18-19-24

Was gonna take my car for a dyno run but after see the log, i think i will wait a bit first lol.

Any chance of anti lag (2step) and no lift shift coming to the mhd platform? I know the n2mb does this but not looking to add any extra modules to the car.

Hey all, after updating to 1.60 I have noticed quieter burbles on the OEM setting. I'll give the next step up a try. I recall someone mentioning this earlier for a different version.

First Flash!

Flashed my car for the first time tonight and I am thoroughly impressed.... I want to go to stage 2 eventually but I think I'll wait for my intercooler/learn more beforehand. Does anyone have a good source for learning how to interpret logs?

Here are some logs from tonight.. I wasn't going crazy hard since I was on city streets but what do you guys think? Any red flags?? Only mod right now is a catless DP. Installing my chargepipe tomorrow before I blow it up lol

One huge discrepancy I noticed is that these same logs show what seems to be timing corrections in the graph but when I upload it to this site they all look flat.

Any help is much appreciated!

There are no timing corrections. Timing drops as load increases. Timing advances as RPM increases.

The exception to this would be the overrun tuning (the noise generator between shifts) where ignition drops negative. You're not making power off throttle and the negative timing is there to make pops/crackles.

Understood. I misinterpreted the graph the first time round. " Timing Cyl 1 CRK" is what I perceived to be timing corrections wrongfully so 😢

Hi, just sharing my experience, successfully flashed my 2012 N55 e92 today for the first time!
version 1.60 stage 1+ with 98 Ron.

Using the MHD wifi orange e-series odb adapter... 7mins Total time! But for 90 it is a bit plasticky, just for comparison the Carly bluetooth adapter feels more solid. Also can confirm that the Bimmercode app does Not work with this MHD wifi adapter (yet?)

Have to admit I was sh1tting my pants with all error messages on the iDrive & dash during flashing but it got to 100% & no error codes, went for quick 10min drive & car feels transformed! Yet to give it a good drive.
Got a air intake, charge pipe, intercooler & oil catch-can to go on soon.

Hope everyone is keeping well.

WOT run question:

I live just outside of NYC and there's not anyplace nearby I can run WOT in 3rd gear until 6500rpm safely. Possibly could do it a 5am on Sunday morning but even then there's traffic - and cops.

Is there any issues with the data you record doing the log in 2nd gear instead of 3rd?

I have a 2011 335i xdrive 6 sp running MHD stage 2 with various mods.

This.

I'd like to additionally call people to be more cautious in these times, regardless.

If, god forbid, an accident were to occur on the roads, you are diverting health and emergency services that could be otherwise utilized for the ongoing issues.

Others are depending on your health and safety.

With the new update, what is the best burble setting for sport mode? it seems to have quiet down with the update but I'm looking for something with a nice pop and being noticeable without being obnoxious to my neighbours.

thanks!

Mine seems a bit quieter as well and appears to have overridden the PPK sounds which were on the car prior to the mhd flash

It's not "ppk sounds" but instead the ignition timing and delay/duration for overrun and burble

Yeah is there anyway to get back those
PPK settings while keeping MHD stage 1+?

No

You'd need a custom tune to modify the exhaust characteristics.

You talking about the usual ppk burbles? I asked the same when I went mhd from ppk. If you had ppk previously when you flash leave the burbles box unticked and it uses the same values as your previous stock flash for burbles so if you had ppk it would revert to ppk burbles! That's what it did on mine and was confirmed by a few people at the time.

If I'm not mistaken he is saying the new update is what caused his change / PPK to get overridden.

I never had PPK and I recently flashed 2+ after having 1+ for a bout a year so I didn't recall my exact settings on the previous flash but while keeping it in the same ball park and flashing a few times with different settings the car overall does seem quieter than before.

Not a big deal though

Strange - mines still same after the update as it was prior so maybe just needs to try reflashing or double checking no settings have changed.

My Report on latest 1.60 map.
I flashed S1+ 95oct (fuel is 98ron)
To start with positives,.
- The car feels more tourqy through the whole rpm range, -bit more wheel spins..
it's a good improvement.

As few others have already mentioned, right after flash the car is more quieter whether idling or driving, I feel though it got louder after a day, and louder pops came back,



Below links with comparison famous 1.51 map, test map Justin sent last year based on 1.53 (my favourite) and current 1.60map

https://datazap.me/u/keyless69/mhd-m...-27&mark=30-29

https://datazap.me/u/keyless69/justi...-32&mark=28-27

https://datazap.me/u/keyless69/mhd-m...-19-27&mark=26


To compare I look at around 4500 rpm data point, as this seems to be the sweet spot.

I mostly do my runs at same place, of course ambient temps will differ.


The figures: at 4500 ca.
Map boost. Torque. Wgdc%. Load actual rail pressure
1.51. 13.2 580* 49.4 166.6* 2228
1.53sp. 13.1 560 60.2 154.2 2153
1.60. 11.5 522 47.9 149.9 2451*


Though the 1.51 had tendencies of over boosting , from the above clearly. 1.51 feels better and figures represent that I think.

On the latest map - was same in 1.54 the rail presure has increased and car is experiencing rail presure crashes at the beginning of the pull.

https://datazap.me/u/keyless69/mhd-m...og=2&data=3-13


Not sure if it's only my car , this doesn't happen with older S1 maps.


Would be nice, if rail pressure would be fixed in current map, if it's a general issue,. Else the experience is positive.

Feel free to comment anything else you see on 1.60 map
