Hi guys,

I'm new here, so sorry for the noob questions... :)
I've a 2.8 V6 30V ACK engine. It was Tiptronic, but the tranny was replaced to a 5spd, and the ecu was recoded to manual too. The car is DBW, and have the ME7.1 ECU. Has 4 cats and 4 O2 sensors, and SAI system, and got the cat and sai related DTC's of course.. :(
I've a Galletto cable, and downloaded the file, loaded it to WinOls but the prog. didnt found too much maps.
I would like to remove the emissions related dtc's first, so started to search for a damos or xdf file...no success :(
The only thing I found on Nyet's site, is a .csv file for a 8D0907551G ecu, but the car has the 3B0907551G. So here is the first question: could the 2 ecu's maps be the same? Because the only difference is the first 2 number.
I attach the original file of my ecu, if anybody can help me :)
Thank for any help in advance!

the values starting @ 18198 are what you want to edit. just 00 them. not all of them though, you want adaptation to work. ;)

Ok, I'll do that. So I should 00 them from 18198 but I'm not quite sure till which number? Till 181b1? What values should I leave 01?
So the 8D0 .cvs file is good for my 3B0 ECU?

what you need to do is experiment and it will make sense then.

no 2 ecus have maps in the same *exact* spots. not that ive seen anyways. might be close but you will spend a lot of time looking at hex trying to sort them out.

your looking at a euro s4 g-box file.  its not going to be the same as you arent an 2.7tt motor.

as kompresed said look through the damo's to get an idea, find related hex between your .ori and the damos, you should be able to find out what you need to change to get rid of your CEL's

every me7 ecu i looked at has the 02 sensor stuff in the same area.  so you should be fine.

if you have issues let us know id be happy to help.

Thanks for the inputs guys. I have a Galletto clone cable, so I downloaded the original file. No problems at all.
I used WinOls to get rid of the CEL, saved the modified file, and tried to download to the ECU, but it failed..:(
Now I dont have the EPC and CHECK lights, and the car doesnt start.
What can be wrong? Should I try to download the original file back to the ECU?
The Galletto downloads the file up to 50%, then says turn off the ignition for 10s and then turn back.
I'm trying to flash it over the OBD port.

galletto needs boot mode and a bench cable

Can you offer me a good webstore, where I can find a good bench cable?
Or is there any other way to re-load the original file to the ECU with that USB-OBD cable?
Now my car is dead, Vag-Com cant see the ECU, and Galletto always stops at 50%... :(

i use a galletto clone and it will flash over obd. but having said that, youre going to need boot mode to recover your ecu.

are you in the usa? i have a bench cable and can recover the ecu.

No sadly...I'm in Europe (Hungary), thats why my english is poor, sorry guys  :D
But I've a US spec. Passat and nobody knows the US VW's-Audi's here.. :(
So I have to do it myself and it would be very nice if anybody can help me how to do a bench cable.
I have only USB ports.

heres some pictures of the harness i have. http://mycarbl0ws.com/harness.zip

your post won by a second. lol


You don't need to buy a bench cable, making one is very easy.

This is the cable pinout for a ME7.5 - 1.8T, you should check if your ecu pinout is the same.
ECU
GND - 1
+12V - 3
Kline - 43
Ignition - 62

OBD-II connector
GND - 5
+12V - 16
Kline - 7

I will try to upload pics later today.

Thanks guys!
At first I'll need an ECU harness and a female OBD port from a yunkjard, then I'll add +12V, GND and K-line to the ECU and that's it?
The clone USB Galletto cable will work fine?
I've the ME7.1 so I think the pinout from that website will work. (is says it is for ME7's)
Can I use a battery charger to add power because I do not have a DC supply?

Here are the pictures

If you gonna use a battery charger attach to it a 12v battery to smooth out voltage pulses from the charger or use the battery alone.

^thats a pretty creative cable set up.

btw, whats up with your original file? winols says 10 out of 73 chksums are incorrect?

It seems that the file he read with galletto is wrong from the begining, but I couldn't find a ori to check this. Try asking for a original dump at chiptuners forum.

also, size of file you posted is 1Mb, but this ecu hasn't a 29f800 flash, has it?

I tweaked the ECU with Lemmiwinks to run the car with E85. Couldn't it be that the wrong checksums are there because of this?

no. lemmiwinks edits settings in ram then they are written to the eeprom when the ecu powers done. has nothing to do with flash. you need a real ori file.

Thanks, here is the schematic diagram and pinout reference

That schematic helps a lot, thanks!
Btw I still need the original file of my car...

Guys! I made the bench cable, downloaded the modded file (without rear cat monitoring and sai) to the ECU in boot mode and.....THE CAR IS RUNNING AGAIN!!!!  ;D ;D ;D  Thanks the lot info and help!
The next challenge is to find all the important maps in the ECU  :) :)

16375 and 16441 are ignition angle, i think. i could be wrong.

I'm running the car with E85. I would like to run the car a bit leaner @ part throttle, and a bit richer @ WOT.

I have the 8D0907551G.csv file from Nyet's home page, but its completely different from my 3B0907551G ECU.. :(
If I 00 the values at 0x181a2 what the 8D0 file tells me for disabling the CAT monitoring, nothing happens the dtc is coming back again after a 20-30 miles. If I 00 all the values, then I wont have lambda control..(because I turned off the adaptation too?)
I tried to find a d@mos or .csv or any helpful file for my ECU on many forums, but nobody answered, or nobody has the file for this ECU  :(
Can you give me tips where should I start search, or what adress I need to change to disable the cat and sai monitoring?
Btw how can you guys tell that what map doing what from the lot of 1x1 map?  ???
Thanks for any help in advance!

Diagnosis is starting at 18194 and fault code at 14A56, you want to disable both.

I know that diagnosis starts at 18194, but there is 31 1x1 map, and I cant figure out what adresses should I set to 00 to get rid of the emissions related DTC's.
So guys the questions is still the same, how could you tell what map means what code or diagnosis without a damos file?

If you dont have the D@mos file, then I guess that the MAX flash you need the do is 31 to find it. :P

In 8 bit and hex try set this to 00.
1819E
1819F
181A3
181AB

hahah yeah thats true ;D anyway thanks for the adresses I'll try it!
and I have another question too hope you can answer it..I'm running the car with E85, and tweaked the ECU with Lemmiwinks. Runs great LTFT's are about 4-6% so that okay. But the cold start is crappy so I would like to add more fuel on cold startups..Is this possible and if yes, where is the map for this?

Think 11ED8 16 bit is where it start. starts high and end low value.

Try to see if it works. I dont have the Dam file for this car so its the best I can do

I tried to set these to 00 but the DTC's came back  :-\
What you guys think, is this possible to find a d.mos for my car?

Post the DTC list. I think you also need to disable the DTC for the oxygen sensor heater amplifiers.

Ok seems like we missed something. Might be the heater. But difficult to find without the Dam. I could proberly get it but damn expencive.

These are the DTCs:

17931 - Crash Signal from Airbag Controller: Implausible Signal
        P1523 - 35-10 - - - Intermittent
16816 - Main Catalyst: Bank 2: Efficiency Below Threshold
        P0432 - 35-00 - -
16806 - Main Catalyst: Bank 1: Efficiency Below Threshold
        P0422 - 35-00 - -
17831 - Secondary Air Injection System: Bank 1: Insufficient Flow
        P1423 - 35-00 - -
17819 - Secondary Air Injection System: Bank 2: Insufficient Flow
        P1411 - 35-00 - -

Try 181B0 for secondary air system

So there are people who have d@m files for every cars, and they sell them for a lot of $$?
What about the TunerPro .xdf files? I found some S4 files on Nyet's homepage. From where could he got them?
I tried to search many chiptuning forums, started threads to ask for a little help but nothing. Nobody knows nothing about this ECU, or just wouldn't like to share the info..
You guys are so helpful here (thanks for that), but now I see that without a d@m or .xdf file its hard to find the right memory blocks..
Btw I'll try every tips, maybe some of them will work so please feel free and dont stop to give tips  :D :D :D

181B0 was already set to 00 in the ori file..
At 14A56 the value was 01, tried to set to 00 to see what happens. Btw what means that trouble codes start here? The other values here are FA, AA not 00 or 01. I dont understand why..So I need to 00 just the 14A56?

I think 14A56 is where fault code area starts, here you can set 0 to ignore cel but it's difficult to tell which byte is the correct one without the dam

Some tuners have access to alot of those Dam files, and some actually make them by them self. A few tuners have the *INCA* software that can generate  the dam "A2L" files to import in winols. So im sure that a dam file is also available for you software version.

I'm looking for the d@m file for this ECU, can anyone point me into the right direction?, it's an Euro 1.8T

  :) hello everyone. Good topic , I wonder what it was all over . I have a car Passat b5 2.8 V6 Motronic Benzin ME 7.1 001 AMX 142Kw 3B0907551CH 0261207469 with the same problem, remove the catalyst and the errors were the second lambda . Maybe someone has already worked with 3B0907551CH 0261207469
