Flashing ZGW with esys

Edit:

At this point in time I suggest to not experiment flashing the entire car with this procedure until we have thoroughly done our post-flash analysis.

For now success is confirmed only for targeted flashing purposes within the same I-level as seen in the DME/EGS flash thread, but not for the entire car.

There are still unresolved issues with faults in the ACSM module.

It is the airbag/passenger restraint ECU and fiddling with resetting or initializing it without proper knowledge can cause trigger of the airbags.

Be patient.

------------

What would be the way to successfully flash the ZGW gateway module? It does not pass. Does it require a different process, it being the Gateway?

Do I need to use a 'Direct' connection? Maybe a different way to calculate the TAL for additional steps?

In normal TAL processing for flashing a module, the log begins like this (CAS example):

TAL execution started. [C205]
ExecutionID=2013/05/23-21:04:13.477
[] prepareTALExecution started
[] prepareTALExecution finished
[] prepareVehicleForFlash started
[] prepareVehicleForFlash finished
[CAS - 40] prepareECUforFlash started
[CAS - 40] prepareECUforFlash finished
[CAS - 40] authenticateECUforFlash started
[CAS - 40] authenticateECUforFlash finished
[CAS - 40 - swfl_0000074d-007_002_032] Transaction type: swDeploy; Message: TA started
[CAS - 40 - swfl_0000074d-007_002_032] Transaction type: swDeploy; Message: 0% progress on ECUId:CAS_0x40 [0% of swfl_0000074d-007_002_032]
[CAS - 40 - swfl_0000074d-007_002_032] Transaction type: swDeploy; Message: 0% progress on ECUId:CAS_0x40 [0% of swfl_0000074d-007_002_032]
[CAS - 40 - swfl_0000074d-007_002_032] Transaction type: swDeploy; Message: 0% progress on ECUId:CAS_0x40 [10% of swfl_0000074d-007_002_032]
[CAS - 40 - swfl_0000074d-007_002_032] Transaction type: swDeploy; Message: 0% progress on ECUId:CAS_0x40 [25% of swfl_0000074d-007_002_032]

etc. etc ......and finalizes fine.

But in the case of ZGW, there is a connection timeout to the ZGW module (0x10) immediately after vehicle preparation and consequently the rest of the car.

This leaves the car in a dreaded Transport Mode but is recoverable with esys by running another random TAL.

This is how a start of the log looks like for the failed ZGW TAL processing:

TAL execution started. [C205]
ExecutionID=2013/05/23-21:19:14.567
[] prepareTALExecution started
[] prepareTALExecution finished
[] prepareVehicleForFlash started
[] prepareVehicleForFlash finished

[] finalizeVehicleFlash started
MCDDiagService id=230900, job=com.bmw.psdz.jobs.common.MCD3_FinalizeVehicleF lash, service=DSC - DiagnosticSessionControl, description=error: timeout, link=Physical request to ECU with address 0xdf

MCDDiagService id=230900, job=com.bmw.psdz.jobs.common.MCD3_FinalizeVehicleF lash, service=DSC - DiagnosticSessionControl, description=error: timeout, link=Physical request to ECU with address 0x6

etc. etc. .....

Any ideas?

Well maybe try with the engine running? I heard the dealer programming session require the engine running.

That doesn't work with esys. Part of the TAL processing initiation step shoots out an error that the engine & transmission speeds are not zero, and actually kills the engine by itself before it continues..

I have solved my problem flashing the ZGW.

In the Connection window, I selected the 'Connection via gateway URL' instead of via VIN, and use the car's IP address with the default port number 6801.

Passed with flying colors

miotoo,

Very impressive!

Please write a DYI for the rest of us. That would be very useful.

Have you tried to flash DME?
Which e-sys / pszdata version are you using?

I know someone who flashed his entire car, but he used E-Sys with ICOM.

What I am wondering is will flashing with ENET work with DME and CAS.

Thanks JEG

I'm still in the testing phase, reviewing the process results and trying to identify potential problems for different scenarios.

The upgrade from 11-03-502 to 11-09-507 was the 1st round of testing I did.

That included 2xSWFL & 2xCAFD updates to the DME.

I have used esys 3.22 and psdzdata depending on the version going to.

I used ENET only.

The sequence & prerequisites are crucial for this process to work hence my baby-step research.

ZGW must be done 1st as it is a prerequisite for almost all modules, and flashing it worked for me using the gateway URL connection rather then VIN.

I had no problem flashing the DME as long as DSC, EKPM were upgraded before.

CAS should be done last.

May you write the procedure and the sequence?
I never update the firmware for any ECU.
My interest is to try to flash my DME to fill in the 528i 6 cyl. Petrol into my 523i (that has the same engine, with sw downgrade).
In my hopynion changing in the FA the engine type (from mine Mt11 to those for 528i, MY51), after calculated FP without errors (maybe esys check the vin with engine type... i hope not) i would try to flash DME.
If i understand well your post, i need to flash other ECU to make that work !!

The procedure you are looking into needs further analysis in order to understand what are the risks and whether failures are recoverable.

Even that esys calculations show no errors, I would 1st confirm that ALL the modules in your car vs the same one from same production date but only different engine designation (528i vs 523i) would have the same hardware revisions. This can be done using realoem/ETK.

I can try to help you out but I rather do this via PM as to not confuse readers of the forum into doing something that is not well tested yet.

thank you very much in advance.
Yes, your help will be appreciate. I will write in PM.
However i'm studying this matter for a year, at least. fxx 523i and 528i have same engine, same dme, same exhaust system. Nothing change (i studied ETK until the last screw, until the last bolt).
Nothing except intake manifold with DISA valves.
On 523i there is one stage intake manifold, instead on 528i there is a three stages intake manifold.
About on 2800 rpm starts the second stage to give more air to cylinders and after 4000 rpm starts the third stage to give the best volume of air.
Only changing intake 523i may take about 10/12 hp. Filling 528i sw into DME engine may take other 40/42 hp.
This isn't extra power but 523i its own power that bmw erased downgrading DME sw (i think that sw in 528i increases cylinders lift valves).
I will write you in PM.

To flash a factory installed ECU using PSdZData is not a challenge, rather it is quite simple.

Where it becomes complicated is when the ECU is not factory installed, and that ECU's I-Step Shipment from Donor Car is unknown and differs from current car, as E-Sys may be expecting a different ECU part number than what it detects, and it won't be able to flash it.

The other complication is what you want to do, which is flash firmware intended for another Model, even if the DME ECU is the same part number. This will certainly involve a) manual manipulation of the VO to have E-Sys create the Flash TAL automatically, b) manual creation of Flash TAL, or c) creation of a custom DME PDX package in place of the PSdZData.

i think i will make changes step by step..
1st of all, because Shawn helped me to find differences in DME .ncd file (between 528i and 523i), I will Fdl code dme changing the parameter Varianten-config by initwert to wert_02.
The assumption is that maybe that the firmware is the same and DME works different with this parameter.... too simple but i believe in miracles

2nd, if step 1st doesn't works, i will leave varianten config with werte_02 value and i will change VO, writing the different production code (523i is MT11, 528i is MY51). So i will try to flash the DME hoping that the ploy will works....

However, i'm lucky because Shawn is a good mentor and now miotoo, too, would to help me. I think i'm in good hands.

Flashing ECU's, here in context of the entire car network, and doing so with a tool we obtained as hobbyists involves even more risks, might require additional tools to recover if failed which are not easily obtainable, and may prevent future flashing compatibility on the dealer network.

I would like readers to be aware of this and the possible cost implications if or when things don't go as expected.

I wouldn't dissociate the risk from the process therefore would not say it is a simple challenge.

With Flashing, bricking the ECU is always a risk. Period. My comment though is only regarding the technical aspects of flashing and the varying degrees of difficulty associated with different scenarios, two of which I provided.

step 1 went bad
I changed VO with engine type MY51, calculated FP, there weren't error.
I fdl coded DME putting werte_02 into varianten-config but esys gave me etherneth DME error.
I tried with its original engine type into VO, but fdl coding gave me the same error.
Last, i changed VO another time with 528i engine type (MY51) and i VO coded directly DME. Esys gave me another kind of error (simply code error).
I think that was the antituning system.
So i have only the FLASH way....

1st of all, because Shawn helped me to find differences in DME .ncd file (between 528i and 523i), I will Fdl code dme changing the parameter Varianten-config by initwert to wert_02.
The assumption is that maybe that the firmware is the same and DME works different with this parameter.... too simple but i believe in miracles

2nd, if step 1st doesn't works, i will leave varianten config with werte_02 value and i will change VO, writing the different production code (523i is MT11, 528i is MY51). So i will try to flash the DME hoping that the ploy will works....

However, i'm lucky because Shawn is a good mentor and now miotoo, too, would to help me. I think i'm in good hands.

And how will you attempt the flash?
