Hi guys ,

I tried to search here , and on the web a full Read for B5 S4 ECU

8D0907551M
0261207143
1037360857

I only found Flash 29F800 reads

I want to clone an ECU and for that i need full read , so in my case CPU/MPC read is missing !

Thanks at anyone who will try to help me !

 ;D

If you got the ecu send it to me, i can make a full read of your ecu

X-Boost Performance

Are you referring to the EEPROM or OTP?

You don't need the OTP for anything, and eeprom tools are available in the eeprom section

Finally, that ECU doesn't have immo so no, you don't need a full read to clone an ECU.

Thanks try to help me .

I am able to make a full read of it , i have KTAG official tool , i'm just looking full read of 551M 1037360857 or CPU

There is no such thing. It's a simple ECU.

Oh okay sorry :) i wasnt know that :)

X-Boost Performance

 first of all , Thanks for you response

I Know how to disable immo on ME7  , i don't need eeprom read i can keep mine .

I cant Clone ecu with just flashing AM29F800 : If i flash SW1037360857 in my SW1037354837 ECU , car don't start , because MPC and flash are not "compatible"

hope you will understand me ^^ sorry for my english

this makes zero sense. Just use the NefFlasher.

Why other information is MPC looking for? What pile of shit program can't just take a flash binary?

please understand that i know what i am talking about .

I Tried to write SW:360857 FLASH in SW354837 ECU , Car doesn't start , its not IMMO , or Checksum problem ( both original or tuned maps , with many tool Chk calculation )

0001 and 0002 should be binary compatible, there is something else wrong.

I believe the ROMs are identical.

I promess you that its a CPU compatibility issue !

If not i won't be asking annoying things like this ^^

What exactly is in a full read that MPC can use when writing, and what does it do with it?

i think a sort of "verification" between them

Its not the only old ecu that you cant flash different SW within breaking it !

Old EDC15 , EDC16 etc are the same , if you want to clone , you need to read/write MPC+FLASH+eeprom

This doesn't pass the smell test. If i had time i'd flash 0001 on my 0002 ecu and prove it :/

In any case, why not just use the correct binary? The map locations are identical between 0001 and 0002

If i had to guess, you're trying copy a file that isn't yours, and it is doing some sort of check in the eeprom.

Ditch that shit and write your own tune.

im not lying , try to test it , you will see ;)

Make a look on google of people who broke ecu with different SW flashing :)

My point is, you can't flash the OTP (by definition).

You can copy EEPROM, but there is nothing in 001 or 002 that care about eeprom contents.

So that leaves your assertion that you can't flash one or the other on ECUs, without a full read.

which also makes no sense. What could a "full read" possibly help with if you can't overwrite the OTP?

AFAIK all ME7.1 ecus are literally identical hw wise.

What do you mean about " OTP " ?

One time programmable ROM.

On M7.1???  I crossflashed many times, never had any issue.

512 kb can't be croshflashed without boot mode
1.8T late B6 and B7 ECU need to move EEPROM also from other ECU
But on 2.7 biT M7.1 croshflashing is going without any peoblems

Ok , so i really don't see how car doesn't start now .

I only make my tune as usual , and try to add LC with Cadensdad14 Xdf method .

Everything looks fine , because my tool accepts Checksum before flashing it

Start by ditching that bullshit. Unless you *personally* wrote the ASM for it (every single byte code), you have no business adding LC.

In any case, this is trivial to test. Flash 001 and flash 002 using the nef flasher or galletto in boot mode. They (or any other hitachi 2.7t 1M manual file) should work, period.

If that doesn't work, something else is amiss.

Thats not for Buisness ! Its for my own car !
I dont know any people here who run in 2.7T , there plenty of 2.0 TFSI here ^^

I will try flashing oem maps with different SW , and report it to you in few hours

He didnt mean it literally, it  means you should not use asm code unless you know what it all does or you wrote it etc. Also I am fairly sure this forum was started with S4/me7.1 :)

Ok , you were  right guys .

Sorry to be so sure of me

I tried to write ORI with different SW  like in description with success

My ori and my old mod file is ok to write , even is SW different .

since i putted my file mod with LCNLS xdf modified , car doesnt start .

I think my ktag make maybe bad writing , even if checksum is ok

First file , car doesnt start , the other one are ok ...

One more time, ditch NLS.

You don't need it. It's a waste of time. Don't use ASM modifications you didn't write yourself.

For christ sakes, either remove the 2 step patch or figure out how to do it proper. End of story, i wish i could have 5 min of my life back inwasted reading this thread. >:(

I really don't get the reasoning here.

IMO if your car doesn't start after a reflash, i'd worry less about the flash tool and more about the ASM modifications you made *by copy/pasting somebody else's ASM*

Modifications that
1) you have no idea what they do
2) you don't have the ability to figure out what they do
let alone
3) you couldn't write entirely on your own if you wanted to.

LC/NLS is fucking cancer for noobs.

Thanks for your response .

I know how to read / write ECUs , from 1992 to 2020 , i know how to remap some of it , i know how to work on Standalone like megasquirt/Ecumaster
BUT
I don't know how to make Xdf modification , including LC NLS .
But i tried , nothing come if you don't try .

If my topic Disturb you , please delete it .

I'm a noob , yes i know , thats the reason that i post here .
But please have a minimum of respect , come on PM ,  you will see i'm not a poor guy who wants to make money , or whatever you think .

NLS is NOT an XDF modification.

Yes i know , i know how to put NLS patch with your PDF wich  explain everything .

But its not as Hard as i want , for that i need to play on Advance during Launch control

But please show a minimum of respect for those who read your question.
Instead of writing a lot of letters, it is better to carefully check your non-starting file.
There is an obvious stupid error and it will not work regardless of whether the calibrations, ASM code or checksums are performed correctly.

no big deal just a misunderstanding
