Performance power kit 2.0 diesel n47

I know a lot have been written about this theme. I have read it is not possible with serial ECU = to inject into serial ECU Alpina soft. There is no need of FSC code for it, so when I flashed entire car to latest F025-14-07-505, I have just tried to add HOWORT into FA, calculated FP (went well) and I tried in TAL calculation to compare SVT_IST to SVT_SOLL what will happend, if it will show update of DME - but not, it is not showing any update.
Its a bit strange ... I do not have PPK DME in my car so it should show update of files or not ?

Or another variant is, those files are not available in psdzdata .... so Esys show no update...

Did somebody already some power increase at N47 2.0 diesel engine ? Powerbox ? DME cannot be programmed at this time (at reasonable human costs). There is one german tuner which knows how to ... So any other tips ?

Just for try FDL coding also doesnt work - coding went well, with green result but DME is always back at "initwert".
"Leistungsklasse = Powerclass".

Will be following this topic as I have the same engine. The kit comes with a new dme, did you check if it's different hardware of just same but with diff sw?

Hi,

I have a F31 2.0D with a BMW fitted M performance pack that raises the output to 200 HK/420 NM.
Would you be interested in my DME CAFD file to compare?

The DME ECU can in fact be 'broken' to do a custom remap. I know one pro tuner who can and I have in fact a mate who have already had this done on an N47 with the MPPK. I am planning to have the same done myself. (still missing the torque from my previous E91 330D )

I have on another forum asked if it is possible to copy/download the DME ECU firmware (customized after remap) from the ECU to a .BIN file to keep as a backup to allow me to change from custom to stock firmware with E-sys flash
- so If you have any idea on how to do this, I'm very interested to hear about this

I know from other forum members that PPK for 3.0d do have different hardware. Because I have not physically any PPK DME in my hands I cannot say that it is same for 2.0d.

But first step I did - after complete flash I added PPK into FP - works, you can see at the picture above, but strange is, that TAL calculation doesnt show any update for PPK DME, as it should do if the hardware is different. This starts me thinking, if in this I-level it is not just matter of software ... but too easy to believe ... but you never know what BMW do in order to decrease the costs ... (lovely downsizeing)

Other strange thing in this latest I-level is, that when calculating TAL for complete flash, going from 14-03-502 to 14-07-505, it was no difference if I have calculated TAL with my original factory FA or with retrofitted FA. (I retrofitted 609, 6WA, 4U2, IHKA HIGH, used ACSM)
Before that I have flashed going from 11-03-512 to 14-03-502 and it was not possible to calculate TAL with retro FA, have been necessary to use original FA for original ECUs to get upgrade and for retrofitted ECU retro FA.
But for last flash it was no necessary - using both FA for calculations always same result.

If the hardware is different, why Esys do not calculate different SW + HWEL ?????

YES, please post your DME(DDE) software configuration - swfl, cafd, hwel, etc..) so we can compare.

Then we will se what we can do.

If you can also show which VO's are added in your FA that would be perfect

I am on the road today, so I will update you tomorrow with the details from E-sys about my DDE config.

In the mean time, do you know if a tool exist that will allow me to extract/download the customized ECU firmware from the ECU to a .BIN file to be used later by E-sys to upload/flash the ECU with?

I am not aware of such a tool but if you look with e-Sys what swfl is in your DME you should be able to grab it from psdzdata\swe\swfl I guess

Yes, the psdzdata\swe\swfl might have the stock DME ECU firmware. However I want to download the customized firmware from the ECU. So I later can change between stock and customized firmware.

E-Sys should have the firmware for the performance DME as well since it's an original BMW part.

OK, let me try to explain in more detail

I will take my car to a pro tuner that will build a custom DME/DDE ECU remap. He will first do a dyno and collect performance data of my car to build the customized remap from. He will then inject this remap into the ECU. He is using some special tools and software to do this and I am not sure he will produce a ECU firmware dump that is compatible with the .BIN format for E-sys to use to flash the ECU.
I will then go home with the remapped DME/DDE in the car.
That's when I then want to extract/download/dump a firmware in .BIN format from the ECU. I will then both have a stock firmware (from the full daten set) and customized version with the remap, so I could change from custom to stock firmware and vice versa.

I hope my intentions are clearer to you now

So my initial question still stands: Do a tool exist that will allow me to extract the customized ECU firmware to a .BIN file to be used later by E-sys to upload/flash the ECU with?

Thanks again for any feedback on this

For what i understood the PPK DDE has an hardware check inside to be recognized as a PPK part.

About the opportunity to read the PPK custom .bin, it will not be an issue. Once read its SWFL file into SVT (we wait for kkaae Svt), we can find it into PsDZdata. Each swfl has three files; one of them has the bin word inside its name. That file has the engine management values.
The matter is:
A) How decrypt that file. Someone was able;
B) once edited that file, the big problem is to sign it with a valid RSA signature and after encrypt just another time with the right checksum.
Why to edit the PPK swfl? Because to make it working in a normal DDE, we need to delete the hardware checking!
BTW for my swap by 523i to 530i i tried that way (edit 523i swfl with 530i read swfl values) unless any result. I'm not a tuner but i engagged many of them...

@kkaae, i just read your latest post.
So you didn't buy a PPK kit but you tuned your own DDE swfl.
If i understood correctly, esys will not have any Solution for your question!
But if your tuner is able to work on your swfl file ad i described, you could ask him to edit the original swfl outside the DDE, working directly on that bin file taken into PsDZdata folder.

I think @kkaae means he has M Performance Power kit now but still wants do to tuning . I would say it's a waste of the power pack, better have your original dme tuned?

BTW, esys will not give him the opportunity for reading the customized swfl, if his tuner will work directly over the DDE.
Instead i think that PPK will be a better point to start tuning, thank to the bigger intercooler.
But the best Solution could had been buy only the intercooler and tune the original DDE.

I'm not really sure that is possible to tune Fxx series dme/DDE, however... Are you sure?

There seems to be one german tuner who can brute force dme. They swsp dme to make orocess faster for customer.

This question can be answered : BMW ECU Explorer. But I do not have it.

Do not forget that you need to get CPS (Coding Prüfstempel) for DME. I am not sure that with dump from another ECU with different serial number you will be able to get it working in another one. But again, BMW Explorer is may be a solution. May be somebody who have seen this soft working can comment more ?

Yes, as I wrote above, in Germany is a tuner who opened DME for tuning. But I already mentioned this is not available at reasonable costs ...

Something like this also my intention. Using 4U2 I would like to let Comfort and Eco Pro at original BMW stock values and with activating Sport and Sport+ to activate customized firmware. But may be it is only dream. But using ICM and CAN signal which activate Sport mode it should be possible.

Thanks for all the great comments! This has become a great thread!

Just to clarify:
I already have the M Performance Power Kit (MPPK) installed in my F31 320D, so that it now has 200 HK and 400 NM. However comming from a E91 330D, this is not enough for me

I have a friend who have a F11 520D also with MPPK and he has had a further DME ECU remap that raised performance to 220HK and 420 NM. The tuner opened up the DME ECU and did a custom remap with dyno before (before showed only 192HK) and after. Cost was €600. The tuner is highly respected and I have had my previous 2 BMWs remapped by him - E91 330D was raised to 290HK and 580 NM.

My hope was to have a copy of remapped DME ECU firmware along with the stock MPPK DME firmware and change by reflashing with E-sys.
@standa: I dont't think it is possible to change on the fly, that would probably need an enhanced ECU.

I will connect my later today to find the software config in E-sys of my MPPK ECU.

kkaae,

driving experience switch (4U2) changes "on the fly" as you said. From live data of the engine I know that it is not only gas pedal characteristic, there is also "injection time or injection volume a little bit changed... such change during engine running is possible in DME - if you can open it for import of remap software, adjusting of just existing values will allow this.

But to open DME - the pro tuner you are talking is in Norway oder Denmark ?

The pro tuner is in Denmark, near the city of Aarhus.
I will try to get some details from him about how he does the unlocking af the DME ECU - if he want's to share
