As promised, the excell-file.
Now trying to identify the source of this file....
Anyone who knows, please chime in.
Thanks,
PvL
Hi PvL I found it some time ago, but I don't remember exactly if it was from Golf4.de or Ecuconnections forums  . But I remember that the person who posted it mention that was like a general descriptor file for M383 ECUs...... but I can't imagine that. |

Although AEB & AGU engines are mechanically similar it software code is a little different, but basically all uses the very similar ECU map, almost 99% equal between software versions or revisions.
The main problem with DBC (drive-by-cable) engine it is lack of live tunability and as that are old engines that was harder to tune, not many people still support it. If fact seems to me that a special or not so common software/OBD cable was needed to reflash these Bosch M3.8.x ECUs.
Many of the maps done for that ecus/engines need to be emulated and/or tested before use.

I think that KW1281 support flash & eeprom management (read & write) but is really slow compared with newer KWP2000 ME7xxx, ME9xxxx, ....... Also are old ECUs with poor live tunability like you say. |

@ 99pwr :
Thanks for your input.
Sadly this is also not a M3.83 damos descriptionfile..... the saga continues...
Cheers,
PvL

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.
From what I gather, these ECUs use an Intel processor and a 28F200 flash chip unlike the ME7.x stuff that I'm finding more information for. I'm going to take some pictures and try to hot-air the flash chip off one of the ECMs this weekend to read it. I have a pretty decent set of gear (SMD rework station, scope, logic analyzer, EPROM prorammers, generic FTDI USB cable, 16bit EPROM emulator) and a decent amount of reverse engineering experience (Honda/8051, Honda/66K, Honda/SH4, Ford/8061, Ford/MPPC) but not a ton of time right now (3wk old baby) so progress will probably be a little slow.
Anyone else working / interested in working on this platform? I imagine there is going to be a pretty decent amount of code analysis that is going to have to be done with IDA, etc. before it's going to be very usable. I'd love to try to find some more documentation on tables and workflow on ME3.8.x if anyone knows where to find such things so I have a better roadmap of what to look for.
Thanks!

I had been interested in this topic. I've done some mapping from M3.82 to M3.83 tables. Many tables are similar but are located at different offsets. Using knowledge how curve shape should look like for particular table it wasn't difficult to match and identify it. Some tables are equal and it helped to locate other tables in the dump. Many tables were "hidden" becasue WinOLS couldn't recognize them as maps due to unknown dimensions.
Actually I took .OLSs file from M3.82 ECU (D014B0907557B 1.8L R4/5VT MOTR D020261204806103735812755/1/M3.82/05/400700/DAMOS30N/30N03-S/30N0302-S/170997/)
and compared tables with M3.83 ECU from AGU engine (06A906018CG 1.8L R4/5VT MOTR HS D020261206518103735212757/1/M3.83/03/400303/DAMOS3P1/3P10103-S/3P10103-S/160499/). Then added these maps in WinOLS Demo. Result is attached. I see this as a good start for discussion/tuning.

@ automan001 :
Good job you've did on it. I'm doing the same right now for the V03 version
of the R-computer from the golf. But manually. like you said, a lot can be found.
With the aid of winols, and it's detection-function, it's quite clear where the maps
are, for the ones described in the 3.8.2 compared to the 3.8.3. Sadly, no one has
taken it on, to produce a full descriptor file for it. So we have to spend lots of hours
doing it ourselves (when time permits). The little maps, and constants are most time-consuming, but the effort will return itselfe soon.
Within time i will put my version also online, so people can have a look at it.
Cheers,
Pvl

Good work friends. I have been playing without luck to make a definition in TunerPro for M383 1.8T AGU 06A906018CG ecu but it needs a lot of work and time to define maps and constants one by one. Then thanks a lot for the info about this topic.

i came across one of those ecus and starting slowly constructing the damos the main difference i noticed is that the ignition maps are 16x16 instead of 12x16 for older ecus. The ecu has code xxxxAR D05 i can share if anyone interesting. I also have problem flashing this ecu with mppsv12 i get security access error code don't know why. Regards.

Dono if you know it but you have to give 12v to pin43 of the ecu.

Yes thank you for the reply i know it. If i don't give 12V i get an error saying no programming voltage. I tried in car and on bench still get security access error. Any other ideas?
