Thats just been my experience.

I flashed my car to stock and flashed again my MHD OTS stage 2+ tune and the error went away since. It's been two days without any issue. It seem to be related to MHD tune.

Yeah MHD pushed the n55 PWG tune out there then went onto other platforms.. They didn't spend much time on it like they did the n54 or the n55 EWG and they pretty much don't support the PWG anymore.. They haven't responded to many many issues with the tune including the overboost issue.

They haven't put an update for the n55e since March.. Had 6 updates to the to the f/g series since.. And they don't mention any n55e for as far as I can see.. So it seems they will sale the product but good luck on them fixing any issues for this particular engine..

I agree... MHD just addresses app updates on features, but Twisted Tuning in NY manages the OTS tunes. I don't even know they care much anymore. All OTS tune is based on the 135i N55 DCT. I guess PWG is somewhat PITA to tune in order to satisfy every E-series customer. I even doubt they look at Anjuna's thread on N55 tuning in general in order to improve PWG drivability. I'm not talking crap, just tell it like it is.

This is a copy-paste from another thread. My post.


I replaced my valvetronic actuator this past August and everything was fine until 3-4 weeks ago when the thing started coding again. I saw the above post yesterday and reloaded the stock bin file using MHD. Wouldn’t you know it, no more 2e0f. However, I now have code 375c: the DME has been tampered with. Great.

I guess I’ll try to load the BEF tomorrow to see if all codes disappear but I’d like to know for sure (if there are no codes) if the valvetronic is actually working. I’ve got a cable on order so I can run ISTA so I can get the thing to cycle.


Follow up: I loaded the BEF after running the stock bin for a day and there are no codes. None. However, I still think the VVT is not working so I’ll wait for ISTA to settle this.

2nd Follow up: It took 5hrs to get my laptop setup with ISTA -not complaining, there are some huge database files and it's not an easy self-install kinda thing. Hooked up the car this morning, ran the VANOS (cause I was in there) and VVT tests. No problems found. I even ran the wiring harness and relay tests. No problems. Why have I not had ISTA in my toolbox before? It's a must-have.

So, everything appears to be functioning normally. In all my research, I did find a YouTube video on recalibrating VVT that mentioned that any time you reset adaptations you should also recalibrate VVT. Maybe that explains the MHD-2E0F connection?

To me this is just another sign of how underdeveloped these tunes are for the E N55, regardless of source, with the only exception probably being Dinan (thanks to their relationship with BMW during those years).

sheeet my nga I even have difficulties tuning mine with fine detail.

I'm on my 308th revision.

But, getting damn close and hitting my target of 19psi

Much respect on that. I don't understand crap on tuning but i do pay attention to people's comments and my experience with MHD stage 1+ tune... I had valvetronic issue early this year and fried the DME. All is fixed now but i'm iffy about flashing stage 1+ again lol

And apparently there was a faulty wire which was fixed and car was fine
Now problem has returned with a whole lot of errors. Where do i begin to sort
This out

Active codes with MHD
2DCE - Valvetronic System no adjustment poss
2EOF - Valvetronic System deactivated adj fault to frequent

Shadow codes with MHD
2DDO - Valvetronic System control deviation warning threshold exceeded
2E11 - Valvetronic System bottom limit position learned

Got the exact codes today. I'm MHD stage 2+. Also Happened to me 6 months ago when I first restarted the car after installing new battery. Did the same thing today that I did before, and that was reflash the tune. Had to do it a few times this time as the codes were coming back. Shadow code is still there but Valvetronic is working.

Could be a coincident but also noticed the PCV valve whine yesterday night for the first time. Did the oil cap test and sure enough it's the PCV valve whine.

Gotta love these cars....

[Street of Rage]

I found this.....

If you have the shadow code 2DD0 only, try let the fuel pump prime for few seconds after pressing start only (accessories on), then start the car (when it's cold)

Just a thought...

Also if you have a catch can, make sure the silicone hose isn't the squishy kind. That would probably affect the pressure, causing pcv blown out and lead to valvetronic issue.

I'll check that, thanks.

Forgot to note also that yesterday the codes are accompanied with the engine stalling almost immediately after startup.

Engine stalled this morning on first startup too but then started up fine afterwards. Haven't scanned it yet but it felt like Valvetronic was active based on throttle response and startup roar. Normally the MHD "startup roar" doesn't happen when the Valvetronic is disabled...at least from my experience.

All, I just went through all this with MHD and valvetronic.

Look at post #48 above. I just added a second follow-up.

MHD tune may well have been underdeveloped as Twisted Tuning in NY is the tuner. I had my valvetronic issue that led to bad DME (unable to erase the fault code). I'm hesitate to flash MHD for now. Maybe MHD should hire different tuner who will put out revisions and communicate with E-series users more often...

[Tunafish]

That would require the platform to be supported.. Only way that will happened if you can get a list of people that DME failured using product (your not the only one) and get a lawsuit involved. Then they might fixed the DME bricking issue but still probably won't fix their maps..

Yep.

The MHD maps are trash.

They have tweaked a few values that influences a few parameters (boost, timing, vanos, etc.) but they did not realize that there are a LOT of tables to change.

Changing a few things fucked up a LOT of things.

I am at the point where throttle body is open all the time and valvetronic is directly responsible for throttle. Also, for my F25, there are NOT simply like 6 VANOS tables, there are

exactly
54 VANOS tables
14 Ignition tables
12 pedal throttle tables
11 Valvetronic tables
and so so so many tables relating to boost, fueling, transmission control, etc. etc.

[drwillb]

So, I just threw the 2DCE code again.

I’ll hook up ISTA again tomorrow and see what it says.

I was feeling like this was all good and stable and talked myself off the ledge without jumping into a Dinan flash but now I think I’m just done with the MHD/BEF crap.

That and the constant overboost. Map1 target is 13 psi but now and then I’ll hit 20.

Do a custom tune and get ride of the bef. I am starting a diy tread for it and its not hard https://www.e90post.com/forums/showthread.php?t=1787691
I havent finished until my weekend but i will also be shareing tunes. I have PPK that you can flash for 98G0B https://mega.nz/file/9KpDSAqA#Gsn3na...vrQ1J11XiWEZzU or my stage one that i got rid of the overboost/throttle closures https://mega.nz/file/JDI3jKDS#SdKld-...VNbpZFVcP12h9U

Thanks for the post.

Is your PPK bin good for any of our engines? Mine is a 2012 N55 that had the locked DME, 9E60B.

[TunafishE93]

Its for a 98G0B so I think not. I have not researched compatibility but do know its for 98G0B. I have a 2012 N55 that I used the PPK bin for but I also have 98G0B.

Is the only way to flash these maps with MHD? I have JB4 currently, but no MHD is there any other ways to flash BEF? Kinda sucks that N55 doesn't have the BEF flasher only license like the N54 MHD offers

[TunafishE93]

The maps i posted are for MHD. Not sure how that translate into other tuning software.

I'm just a newb in general. I subbed to your thread I will definitely look into the tunerpro software and learn.

Is the unlocked DME from factory (late 2010 - early 2012) 98G0B? Mine's a 2011 e92 N55.

[TunafishE93]

From what I see the 98G0B is 2011 to 4/2012 and 96E0B is 4/2012 up.
