PVL,

"I'm already happy that i don't have to solder and socket stuff with these."

Care to elaborate a little more? I saw your post about +12V on pin 43. How do you read/program from there? If you could explain the algorithm or point me in the right direction on that I would greatly appreciate it. I still have three or four ECUs with chips desoldered off them in the basement - I'd love to not have to break out the hot air station so much.

I've already started trying to take apart the code with IDA. The 80C196 onboard in the ECU has 48k of onboard memory which I have not managed to read, yet. I can't figure out which address in the memory space the Flash chip occupies. I haven't been able to disassemble much of anything that makes sense from the flash chip, which is leading me to wonder if it is used exclusively for calibration data with the "operating system" if you will living inside the main processor. There are tons of tables obvious in the data structure of the 29F200, that's for sure...

The processor is a intel processor, so no ME7.x kinda
siemens comparable thing.

Try to download some original files, and winols will tell
you the processor, if it's known @ evc-germany and
they programmed the recognition in win-ols.

Processor: Intel 80196

Hi Dave,

After hot-air-reworking these, i get fed-up if wanted to tune them frequently.
Therefore, a nice interface like MPPS is the solution. Like i earlier described. No fuss,
and quick reprogramming of all flashrom-equipped ME3.8.3 and M5.92 ecu's.

Most of the files of these boxes are findable on the net, or on the very common ebay-dvd's
as these ecu's are a bit older than the newest ones in the current .a.g. cars.

That disassembling thing with IDA is very nice. If i had the time, i would also help with that.
I'm a bit of a lazy person, and i know for 101% that there is more info about (like a full
damos-file that explains all stuff. Then the disassembly with ida makes even more sense, and is speeded-up like LIGHTYEARS).
I would be happy to donate some cash on it, but no person yet has contacted me, that he has a full damos or a2L descriptionfile of a 3.8.3/M5.92 ecu..... sadly...

perhaps the one from kompresd can give us already some insight info as of map-positions/specific maps. As the 3.8.2 -> 3.8.3 is normally a slight update or enhancement.

A 1:1 comparisment would reveal more.... i think. Now i only have to find the time for this... As this is already complex stuff...

If you have a logging-device for obd2-ports, as of hardware ready to pass on, i can put it between the obd-plug and the benchflashcable what kinda handshaking and protocol is used to program them ecu's... any suggestions or tips ? wuold like to log K+CAN lines for studying the way they interact with the ecu.

Cheers,

PvL

You can construct a "vampire" device by using something like a MC33199 tied to a FTDI232. cheap, simple.

From ecuconnections:

Quote

... All 5.92 ecus have 29f200 inside and are flashable. MPPS and SPI. However, you need to give 12V to pin 43 in order for these interfaces to be able to write.
Or, unsolder and solder.

ME 5.9.2 is closely related to ME3.8.3.
They are saying it's writable with 12v on pin 43 via MPPS or SPI. However, you CANNOT read the flash in any case and Galletto doesn't work at all.

I have been able to read the eeprom and flash memory inside an M383 and M592 ECUs using Monoscan. Of course I can not write it.

I have a 98 A4 1.8tqm and I've been toying with the idea of messing with the ECU in it. I bought 2 or 3 557 and 558 ECUs to have as spares.

Dave can you post some front pics of the ECUs you have? I mean, the main circuit side of the ECUs. I will appreciate it. I have been playing around with M383 and M592 ecus and I want to check something about Audi M592 ECUs.
Thanks in advance for your help.

hi to all
this is my contribution to this post.

this a damos file for a little old me3,8,3 ecu (0261204806)

btw... i use original MPPS interface, and its posible flash these type of ecus sending 12v thru OBD port with a little modification, 12v need to be sent in all write operation, and in a specific pin of obd port. in some cases will be necesary remove Fuse11

hope will be usefull

@ jpi512 :

Sorry to spoil your party, my friend. But i gotta correct your post a bit.

The damosfile you've posted, is a M3.82 NON-flash version, sadly. The
thread is about the 3.8.3 (flashable version) Have a look to my screen-
print i've made, rooting trough your damosfile that you've posted.

If you have more of these files, please look into them and see if one of
them does state M3.83, as we then have a winner !

Cheers,

PvL

Friends I think I found something related to descriptors of M383. Please can you check it out.

@ eliotroyano : Great !

Thank you very much. Now doing a Excell-port from this file and some
minor corrections on it.

I hope that this corresponds with one of the 3.83 files.
You don't happen to know the vag - or boschnumber of this dump ?

Will post the Excell-file of this asap

Greetings,

PvL

As promised, the excell-file.

Now trying to identify the source of this file....

Anyone who knows, please chime in.

Thanks,

PvL
