NefMoto

Hello everyone,

I have a Seat Ibiza 1.8T with AQX engine. My ECU is ME7.5, and I will upload a photo of ECU.

I have been trying to use the NefMoto software to download the map. But when it gets to 6% it blocks. I chose the 29F800BB, because when I try 29F400BB says that it appears to be a wrong Layout.

Can someone help please?

I will upload the log as well as an ECU photo.

Cheers

Can someone please help?

I have tried different Baud Rates as well as Layouts and nothing. Download crashes bellow 10%... plus the program keeps on disconnecting.

Any ideas on how to solve this?

Thanks

Your ecu memory layout is 29F400BB. Probably can see it also by choosing Read ECU info with 52800 baud rate.
Set baud rate after connection to 52800 and then try to Full read flash with the above layout selected.

After those wrong tries you have made, perhaps you wont be able to read it this way so you have to try bootmode.
If you are not sure on what you are doing read as many threads you can before bricking your ecu.

Dammit ignorance is a bitch... May this error serve for future searches. (btw: the car is runing OK, guess I'm just lucky)

I did read a few threads, and the "conclusion" I got to was that my ECU would be read with 29F400BB layout, if not, 29F800BB. But when selected 29F400BB in the program and ok, it showed a warning saying that the layout appeared to be wrong, and asked if I wanned to continue. I said no and tried with 29F800BB without warning.... or sucess.

I will be trying with the 52800 baud rate soon and will tell here what happened. Thanks a lot for the response professor (and sorry for the mess I guess :S)

Yes it shows that error but in my case i press ok and it read it ok.

But i had the backup if something goes wrong to go with bootmode.

Yeah, today I tried again with 52800 baud rate, and the 29F400BB memory layout and couldn't download. Happened the same thing: when arrived to 6% the download crashed.

Guess only with the boot mode now :s

Try running a direct K-Line and bypassing the cluster.

And can you explain how to do that, or point me in the direction where I can find out? Thanks

Remove cluster's fuse.

That's not even nearly the same as what I said...

sorry for digging this here out but i have the same Problem with the same engine

im using a VAG KKL 409.1 Cable.
I'm no Native Speaker so i dont understand what you mean with bypassing the cluster by removing the cluster's fuse.
Where can I find that "Cluster's Fuse"

Step 1: copy your mailadress
Step 2: pasting your mailadress to facebook
Step 3: your from germany so you speak german
Step 4: translate.google.com or dict.leo.org
Step 5: "Sicherung des Tachos ziehen"

Thats what they suppose to say by "pull the dash fuse" or pull the cluster fuse"  ::)

oh, im so sorry  ::)
Thanks :)

ok, now i've tested but it just won't work.
Is there a other option than doing it with boot mode?

aftermarket head unit?

which is "radio" in german

Uhm I have the original Radio but ive puttet a second Radio in it so i can use USB and so on. Both of them have full functionallity. May this cause the Problem that i cannot read out my ECU?

And thank you for helping me out of this misery and trying to answer in german words :)

I have a second head unit which is fully original but hasnt climatronic. Should i try to use this one?

Try to remove the headunit fuse or remove the whole headunit.

I know this could be a problem with mpps flasher. Maybe its the same problem with nefmoto software.

The other way would be to bypass all other k-lines in the car.

I'll try this when I come home later, thanks.
A friend of mine has the original ross tech cable, maybe with this it works. I'll Post if it works.

The solution is to run direct K-line to ECU! If you can not do this, bench flash.

Ok, but how Do i connect k-line direct?

There is a single wire a lot of the modules in the car use to communicate. It's referred to as the K-line. This wire goes from the ecu to the instrument cluster, then out on another wire to the OBD port. In some cases when you have communication issues, running a line directly from the ecu to the OBD port allows clean communication. Some have built relays to switch between the factory wiring, and their direct k-line with a remote switch. You basically want a single uninterrupted, (not tapped into line) going from your cable (OBD port) to the ecu. You can find the k-line and cut it between the ecu and the instrument cluster, and tap into only the ecu side. After you're done reading/writing, you want to reconnect it the way it was originally. Hope this helps!

UPDATE:
Now i have successfully read out my ECU but as i was reading out in the log it says "this is the RAM Program"
I compared my File with ME7CHECK.exe to a other aex from this forum and they are the Same
Same.

Now i added anti lag and need to know how i can fix the checksum cuz there are 2 Problems with it.

Thank you all a Lot!!

If you can't get it working send me your bin, or post it here, and I'll do it for ya.

Ive correct it by myself.
If you had time, would you tu ne my . Bin to the Same like the cupra r? I dont know how to Set that ive got 283cc injectors instead of 317cc and I wanted a boost about 1.3bars, my wastegate etc brings it but my ECU cuts it off :/
Would be great if somebody who is good in tuning could send me a pm

Sry for my Bad english im a german ::)

how did you read it in the end?

i have same problem trying to read Seat Ibiza Cupra AYP 2002

Fails to read on both 400 & 800 Memory layout

Program and Cable ok as it reads my S3 2002 BAM

I'm guessing he did what prj said, bypass the k-line or bootmode the ECU.

My MY2002 Jetta had nothing but issues reading and writing until I bypassed the k-line. I installed a double pole, double throw switch above the fuse box. When I want to read or flash I flip the switch to bypass the cluster, radio, etc. Its never failed to work since then. I really believe that it was my cluster interrupting communication as I would get random 'security access not granted' (and associated failed reads/writes).

Here is a link to how I did it if you are interested: http://nefariousmotorsports.com/forum/index.php?topic=6679.msg70602#msg70602

I'm not saying this is the correct thing to do. Just what I did after reading advice here to try a k-line bypass...

Have you done this process with the doors closed?

It will always cut connection when reading a file if vehicles doors are open. Doors closed and at around 10% after reading it will lock the doors. I have done a succesful read from the same engine.
