How do you flash this on the n54?

Just wondering, has anyone compared the US vs EU flash? Is there any difference.

I am actually working on your second question right now. I have a friend who is a BMW tech that actually installed a PPK on a X1 before. He is working to get me the part number from his parts department.
Any updates on this for the X1 flash part number?

Also curious if the X1's PPK flash was located in the v55 Datens for you, or if you had another version loaded up?

just found out the zusb numbers have changed with latest daten-files (v57.1)

for example : 8639162 is superseded by 8666694

anyone knows if they fixed the "dont need a FSC for ppk" situation with this ?

My car: 2010 BMW 335i with DCT.
Japan spec imported into New Zealand, equivalent of 2011 US model. It's LCI with the N55.

I had a local BMW specialist try this after I forwarded him the info. He does the Alpina flash so figured he'd be able to work this out.

He said my car had been updated in 2013 by a dealer based on the software versions. He flashed the PPK onto the car and it asked for an activation code.

However, it allowed the car to drive. No error codes thrown, no limp mode.
He reckons the activation code is needed to switch to the PPK map and it'll just be on stock behavior without it. He tested the car and didn't feel the difference.
He left the software on so I could try it.

Short drive home. Not enough to reach operating temp, traffic and low seed limits. Felt a bit more responsive but not sure. Had window down, sound seemed about the same.
Tried sport mode, maybe louder, turbo more audible under moderate acceleration

Parked it at home and revved it... there's the burbling sound! It's not subtle at all, it's loud and clear, combination of crackling and burbling. It's awesome. That definitely wasn't there before, I've revved the car while parked before. It's just like the sound in the videos some people have posted here.

I used Torque + Trackrecorder last weekend and took the car on a good run to see how high the turbo boost went before the flash.
I'll do the same after the flash and see if there's a measurable difference, this will be the real proof if it worked or not.

Ohh boy...

These are full throttle runs before the flash, middle display shows boost:

Views: 1158
Size:  38.7 KB
Name:  Stock3.JPG
Views: 1176
Size:  50.9 KB

As you can see it peaked at about 10 psi under full throttle.

I took it for a run today to see if the flash did anything:
Name:  PPK1.JPG

Name:  PPK3.JPG
Views: 1169
Size:  54.8 KB
Name:  PPK4.JPG
Views: 1167
Size:  49.9 KB

Now thats a pretty clear difference, Im seeing 12 - 13psi consistently! Probably hits 13 each time but my cheap Bluetooth OBD adapter is a bit slow so it misses the peak values.

The DCT transmission kicks down much faster, its near instant now. This might be more due to new software than it being more aggressive, this just makes it more drivable.
Throttle is more responsive, standard mode now matches sport mode in responsiveness but without the hyper sensitivity that makes it hard to modulate.
The extra responsiveness and faster kickdown makes zipping through traffic so much easier.

The kickdown shifting improvement is probably more a DCT thing, I believe the regular auto is fine in stock form but then I haven't tried one

Anyone know if this PPK is overwritten by a backend flash or if the PPK modifies different areas of the ROM? Additionally has anyone tried putting a BMS backend flash over it, or does the newer ROM version after PPK prevent that?

Using v57 datens looks like it has updated PPK zusb for my 2011 135i DCT USA. It went from 8647156 (98G0B) to 8664448 and ROM version is 98G1B. Date is 7/31/2015. Looks like latest Cobb supported rom is 98G0B so by sticking with 8647156 (which I found in v54 datens) it should still be backend flashable. Although still not sure if it will overwrite the PPK sound when you do that. I may try it.

Good find - if anyone's looking at this from a MEVD172 N55 COBB BEF perspective then the two stock BMW ROMS you'll have problems with are 96A0B and 9780B. These are really early ROM versions.

COBB Basically won't flash these due to a bug in the original BMW software so the only option is to either, via WinKFP, upgrade yourself or pay for someone to do it. The process to upgrade yourself, providing you know what you're doing with WinKFP, is identical to the PPK flash posted by Hanswurst.

It's interesting to see the 98G1B BMW upgrade given the age of the cars it applies to - wonder what the changes are? Assuming there's nothing in there from a security / blocking perspective then my guess would be COBB can flash however, I'm assuming at best it will need a dump of the ROM followed by a firmware upgrade from COBB.

I've been through this process (with an older ROM, not 98G1B) with the COBB guys and it's not a big deal (took them less than 1 hour to email me back and provide the firmware) so hopefully should be OK.

The v57 daten files says the latest integration with the 97G1B ROM is dated 3/2015. I wish we knew what the changes are as well. I didn't flash it with that version of the PPK since even if COBB supports it quickly, Terry/BMS would still need to make the backend flash for that ROM version as well.

So yesterday I flashed my 2011 135i DCT with the 97G0B PPK (the ZB mentioned for my car in the first post). After flashing, I revved my engine in neutral and didn't really get any burbles, just like pre-PPK. However once warmed up and I rev my car in neutral I get the burbles/cracks when I let off gas. I wish I checked this before I did the PPK install, as I didn't realize the car needed to be warmed up to get this sound. I only had the car a month so never checked when it was warmed up.

After a bit of driving, I got the check engine light with encoding error code as mentioned on the first post and I used NCS Expert to clear it.

I've been driving with the JB4 so couldn't really tell if the PPK did anything other than the sound (which I hear some people get without PPK / so not 100% sure this is new). Throttle response seems the same as before. I know the flash went through as the ZB # read back correctly after the flash.

Lastly, I flashed the BMS Backend flash, tested revving and still get the burbles/cracks like I hoped. My theory is Cobb flashes only parts of the mapped ROM and it shouldn't overwrite areas of the PPK ROM that Cobb doesn't touch. I could be wrong on this.

Huge thanks to Hans for putting the info out there. I just wish I knew to test revving my car warm before I did the PPK flash so I can have 100% evidence the new sound is from PPK and remains even when flashed with backend flash. Either way, I'm glad to know I get the PPK ROM if I decide to flash my car back to stock.

Hans, can you answer this for me? The 8651804 zusb has been absent from every E89 daten pack I've tried. Not sure where to get it.

EDIT: v57 does not either. Hopefully 55 or 56 have the file I need. Hm....

Ah, thank you! Of course it's in the only versions I haven't checked. :-) I'll have to keep my eye out for these datens now.

In some cases you can view the Daten's HIS file with a text editor and locate the new ZSub.

Thinking about flashing the PPK on my 2011 N55 335 but worried about FSC issues.

My car's current I-Level is E89X-15-03-501

My ecu is MEVD176k with hardware part of 8618483 and current programming of 8639012 (98G0B)

From my understanding, the correct flash would be zusb 8639128

So far I've seen mixed info about FSC codes and also about the MEVD176K

Does anyone have any more information?

Thanks,
Nate

Why are you worried about FSC issues? You can flash back to stock if it doesn't work.

In my case it asked for an FSC code but worked without it. Others have had the car go in limp mode. My theory is there is that there is a 'bug' in the DME software that does not always put the car in limp mode when there is no FSC code, which allows some of us to flash this for free.

Just look for local BMW/Euro car specialists in your area. Thats the safest way to go. Anyone with the right equipment and skills can do this, places that can do retrofits ect.

Everything required to do this is included with the standard BMW diagnostic tools and software they will have.

So I ran into some issues trying to flash. It just wouldn't even start. I think this is because I have the MEVD176k ECU and was trying to flash 8639128 which is for the correct hardware part # but uses the MEVD17 flash method. Can anyone input on this or has anyone correctly flashed MEVD176K? (2011 e92)

Its Written in 1. Post in the Point Warning
- Dont flash if your car is after 2013 or got Update by Dealer after 07/2012!
Only a few MVED1726 will work.

to make it easier the general Rule:

if you have a Zusub xxxx8xx oder xxxx9xx so its MEVD1726
if you have a Zusub xxxx1xx so its MEVD17

another way:
Just Read the AIF/UIF with Inpa and check the ECU Zusub, check it in the E89/Data Folder XXXX.HIS (Open with Editor). if you finde Actual Zusub in the MEVD17.HIS so its your ECU, if you find it in MEVD1726.HIS so this will be your ECU

Dont Play with your Car if you never Flash or use this software before.
If You need Help or Remotly Flash just send PM

Mine had an ECU update in 2013 according to the mechanic who did mine (see my version in my above lost) and it worked. He said updates can easily be rolled back so that wouldn't be a problem anyway...
