OM 612 ECU reprograming - barrote - 01-17-2016
Hello fine people,
Would like to know if someone in this forum that have true knowledge about ECU tuning could give me a tip on wich software should i search for, and how do i plug it to my W203 with the 612 engine.
Intention is to acess the engine ECU program and rewrite it to my please.
Regards to all.

You make it so simple.
But yes, someone could shed some light on it. Once I tried old MSA11 ECU, but for that you need EPROM programmer and something in which you read maps and tune them-Winols for example. Then you need to do checksum on new ECU content and burn it on EPROM. I doubt that old CDIs are flashable.
RE: OM 612 ECU reprograming - barrote - 01-18-2016
Thanks , i see your point...
I dont have a clue about the thing , but since everybody talks about repro´s X and Y , i assume there must be a means of build the algorithm so that we can reflash the EPROM.
My question is very simple , wich software can we use to read the EPROM algoritm. and how can we plug the thing , if we can do it without removing it from the board.
Even if they are not flashable they can be replaced by something that it is. or i´m i wrong about this?
There must be someone who know about this subject in this fórum, and i hope they will be willing to share some info.
Regards to all.

edc15c6 with chip like 29f400 or 800 can be flashed (reprogramed) through obd (diagnostic socket)
BUT NOT ALWAYS POSS. TO READ OUT ORIG, SOFT !!
http://www.dx.com/s/chiptuning MPPS, Galleto, etc...
or on the bank.
with programer like this 866 (also need socket)
http://www.ebay.com/itm/USB-MiniPro-TL866CS-Universal-BIOS-Programmer-EEPROM-FLASH-8051-AVR-GAL-PIC-SPI-/221092473435
cheapest but work ok,
ecu that have two chips hhh &lll like this vw ecu can't be reprogramed through obd, put socket and new chips is best way.

It's a long way to know how
THERE is a free editing program edc15p suite (for vw/ audi) but can work with all edc 15
http://socalsaab.com/suites/suites.htm
or ask more on http://www.ecuedit.com/
or post question

RE: OM 612 ECU reprograming - barrote - 01-21-2016
god damm u man ,
thanks a lot its too many info to digest ....
i´ll take a read about all that.
i´m personaly interested in MB ECU´s , since they are my passion ....
anything u need about mech pumps just give me a shout
regards
RE: OM 612 ECU reprograming - turbojet - 01-22-2016
During programming through obd (k line) all on car, ecu go in some boot mode (not all ecu, not all car) and power up radiator / ac fun at full speed,
so people who don't know this can fail programming due to losing battery voltage !
chip desoldering is tricky and cleaning plc board, but have lot on youtube,
-needed is hot air station and small soldering tool, flux and quality soldering wire & Desoldering Wick
for programming on external programmer you need sop44 for plcc chip
http://www.weilei.pl/images/adaptery-uniwersalne-wellon/tsop/adapter-wl-sop44-zif-flash-29f400.jpg
all need to be cleaned 200% to ensure perfect pin contact, some better programmer show bad pin conection and wont start reed/program before all 44 chip pins are ok...
chip need to be placed in right direction (point in corner), etc
there is allot more info but for start enough.......
RE: OM 612 ECU reprograming - barrote - 01-22-2016
as i said , need time to digest .... thanks again.
but i´m very much interested in the ECU for MB CDI engines , specially from 2000 on. after 2004/6 there was changes in the OBD .
so basically is this MB ECU´s
RE: OM 612 ECU reprograming - starynovy - 01-22-2016
I am not new to electronics, so these soldering and programming things dont bother as much as working with program itself. I found maps etc. But what about those checksums?

I'm not expert, can post some example, or tell you that google make wonder
just search (read) this forum, mhh, ecuedit, digital-kaos.
So many craced soft., even vag-suite calculate checksum at end, or some others soft from previous post about obd flash...
very long way
after 2004 almost all producer (who use bosch) start with edc 16 (read -much different-not in easy way)
at the time all producer in the world use common rail:
invented by fiat / magneti marelli 1990+
-bosch who first buy licence, so all fiat/alfa car have bosch (have some deal-licence)
-delphi
-denso
-siemens
RE: OM 612 ECU reprograming - deviance - 01-27-2016
Almost every ECU is check the checksum in the EEPROM/FLASH.
There is an algorithm for check the checksum and create/correct the checksum.
'A checksum or hash sum is a small-size datum from a block of digital data for the purpose of detecting errors which may have been introduced during its transmission or storage. '
So if you change the data in the eeprom the checksum is not good for that. The ecu see 'something is damaged or modified' and the ecu will not 'boot'. Example at early EDC15 1.9 TDI 90/110HP you have no glow blink at ignition and the car will not start. This is why you need correct the checksum.
As turbojet wrote: "vag-suite calculate checksum at end". Vag Suite will never calculate checksum and in the software the checksum correct/checking is not working.
Turbojet you wrote many things but they are not correct
They call itt PLCC32 to DIP32 adapter. DIP32 old one PLCC32 is newer.
In this time you can only buy that programmer what showing what PINS are not correct, need to clean- fix it.
You will erase -> write -> read -> check.
Any question in the future... just write it.
