Okay, so I bought a used ECU and I need the get the SKC out of it. I'm intending to replace my old ecu with that one, but immo3 is the problem. Is it possible to get the SKC out of the ecu at all, or is it only possible to get it out of the instrument cluster? Since I don't ofc have the instrument cluster for the other ecu. I'm all confused  ??? 

I have a genuine ross-tech cable, is this process doable with it?

You can get the login code from the eeprom in the ecu. If it's dead, you need to use an external device. Google the GQ4X with SOIC-8 testclip.

What ECU is it? If it is ME7.1/7.5 you can read it out with argdub's tool over the diagnostic port.

Its theoretically possible with a ross-tech lead, but I have never managed it, I use a dumb kkl lead.

I'm really as out as you can be..  ;D Which one is easier: pull out SKC from both ECUs, or delete immobilizer from the "new" ECU? I just want to get that new ECU I got working in my car. Btw car is Audi A4 B5 -00 if it matters. I have no clue if its ME7.1 or 7.5.

what country are you in?

Finland. How is that relevant  :D

Okay I dont get it anymore.. I managed to read 95040.bin from both ecus, but both show FF FF in place the skc should be in. Whats going wrong? Also I think something might have gone broken since I don't get any readings from 25-immobilizer meas blocks.

I attached both of my 95040.bins, the original and the new one. If someone could make any conclusion out of them.

Also if someone is willing to do so, I'd appreciate if someone took the immo off from that 95040.bin file. I'd just try that out before sorting all this immo shit and see if the original ecu actually went broken.

Looks like an Immo 2 eeprom, which doesnt store the SKC in the ecu.

Getting weirder, because thats exactly what I have come to too.. Is it possible that I have immo 2 ECU, but immo 3 car? How the hell do I do the adaptation?

Is it possible to immo off that 95040.bin? I would like to just try running immo off. Is there an easy way, like a software to do the immo off? I think I can manage to write the .bin on ecu using me7_95040. Or if someone here more experienced could do the immo off for me, I'd really appreciate it.

Immo off really as simple as that? Changing 2 numbers?

yes its simple. 2 bytes and 2 others bytes for checksums

How do I know checksums? I'm not that familiar with these kinds of things.. Is there a calculator that lets me know, or do I just have to figure it out myself? Some tips?

I think I've managed to do it. Someone mind checking if this is done correctly? Attached immo off of that 95040.bin attached earlier.

That is correct.

Nice, I'm making progress  :D I'm planning to write it to my ecu through obd port, by grounding pin 24. I will ground pin 24 to battery minus, right? When I'm looking at instructions on how to get into bootmode, I see powering off and on ecu, and in my case that means turning ignition on and off? How do I know when I'm in bootmode? What to do after the procedure? How to get to "normal mode"?

Cycle the power off, then back on to exit bootmode.

I got message saying: "Unable to open file '95040.bin'. <error=0x04>"

Means I'm not in bootmode, or what? I have me7_95040 on desktop and my 95040.bin also.

That means it can't find the file, you get a different error if it's not in bootmode (I think). Type dir and make sure the .bin is listed.

Now I got: "Starting Boot_mode ... FAIL ... No response from ECU."

That means I'm not in bootmode? Or is there something else failing? What am I doing wrong going to the bootmode?

E: Now "Starting Boot_mode ... FAIL ... No echo from cable"

E2: Feeling little dumb at this point. Thought the pin 24 was the pin 24 from connector, which it seems to not be... :D Well, I'll try tomorrow with the real pin 24 and we'll see what happens.

E3: Meh, still getting No response from ECU.. Something happens tho when grounding pin 24. EPC and Immobilizer dashlights go away. Still not in bootmode I guess, since it doesn't work.. Any ideas?
I think I start setting up a bench to do this shit, if it solves the problem..

Could changing baud rate help?

have you read this post ? http://nefariousmotorsports.com/forum/index.php?topic=5068.0

you have to open the ecu, the pin 24 is not on the connector, its pin 24 at eeprom

"E2: Feeling little dumb at this point. Thought the pin 24 was the pin 24 from connector, which it seems to not be... Cheesy Well, I'll try tomorrow with the real pin 24 and we'll see what happens."

Mentioned already that I just realized that and I tested with the pin inside the ecu with no success.

Is it possible to get a working "rig" with the genuine rosstech cable or will I be needing a blue kkl cable? I did the connections exactly like here: http://nefariousmotorsports.com/forum/index.php?topic=5068.0title=

,but all I'm getting is "No echo from cable".

I have never been able to make the rosstech lead work.

No wonder it didnt work at all since it just burns the fuse.(250mA) Just wondering whats going wrong.

Secondly, is it supposed to ground the pin 24 of the chip, OR ground the SPOT of 24 pin on the whole board? Since I got a board in which the chip is kinda lifted up, therefore mixing the connections a little.

you burn the the 250mA fuse in bench ? try 500mA not more

if I remember an ecu need between 200 and 300mA in a bench set up

I also tried one 300mA I had, and it burned slowly. I mean it didn't just burn like snap, it took more like 10s. Now I'm out of fuses, those 2 were the only ones of the right caliber I found in the garage. Gotta get some more, to see if something is fucked.. So 500mA is still pretty safe to try?

But if someone mind answer my second question that'd be great. I could provide a picture of that ecu if someone needs. Don't know if you already ran into ecu like this before, with the "lifted" chip. I think it has something to do with the fact that the ecu I'm working on now is indeed chipped. But I need answers on wether it's the pin 24 on that chip I need to ground, or if its the spot that it is on on the board, if you get what I mean. Since that spot and the pin 24 in my case are not connected. And if I remember right, I measured that the spot and flash eprom (on this pic: http://wiki.obdtuning.com/images/thumb/9/97/VAG_ME_7_Platine1.jpg/800px-VAG_ME_7_Platine1.jpg) are connected. So I'm not sure which one I need to ground for the boot mode.

humm, you burn a 300mA fuse ? ok don't try the 500mA. something is wrong in your benchsetup or ecu. the ecu is out the car right ?

post a pic of your bench if you can.

for the boot pin, the pin 24 on the picture with arrow is the same as the spot with the red circle. Its just more safer to apply a ground to the spot. and you don't need to lift any pin. you can use one multimeter probe to touch the spot with red circle. you need to plug the other side of the probe to your negative source of power supply

By lifted do you mean there is a riser board where your eeprom should be? Sounds like you chipped ecu which you won't be able to read just by grounding pin 24. Post a picture of your ecu.

Nothing wrong with the setup, don't know about the ecu. Ecu is out of the car yes.

Ok, so I have grounded the wrong spot. Pretty stupid to talk about pin 24 when infact thats not what you are intending to ground. I'll post a picture of my ecu soon.

So here's pictures of the ecu.

ok !

I now understand what you know by lifted  :P

I have already done a immo off on these type of physical lifted chipped ecu, in my case its was APR chip.

the big black wire is your ground to the pin 24 ?

I will write you the exact procedure to bootmode the ecu

1-Ecu need to be power OFF
2-carefully apply ground at pin 24 ( the spot with the red circle is more safer, you don't want to short pin 24 to the pin aside) http://wiki.obdtuning.com/images/thumb/9/97/VAG_ME_7_Platine1.jpg/800px-VAG_ME_7_Platine1.jpg
3-hold the ground at pin24 in the same time you power on the ecu
4-leave the ground 5sec
5-remove the ground
6- done you normaly are in boot mode

Okay, thanks. So I ground that spot on red circle. I'll maybe try tomorrow.

Well this is just interesting. Now I get this: "Starting Boot_mode ... FAIL. <error=0x09>"

And when I get it, my cmd just freezes. I cant close it, not even through processes. I can minimize it and everything, but I just cant close it. Have to restart whole pc. Any ideas? :D

Yap, the ecu is broken. Dunno at what point it went broken, but now it is broken. Any common faults on these that could be fixable? Could I salvage the "power"chip and plant it on another ecu?
