immo off

Thanks for this nice and simple explanation.
Immo off = immobilizer deactivated ?

Thanks.

That's correct Immo off = immobilizer deactivated

Virgin called and the file that we have read from old ecu end we make change which reset to the first stage, unused.

Ok, thank's guys for so valuable info's what you shared.

Here is my first reading result with my first ECU tool which is the Galletto v54 master tool. (clone of course)

I read out through the OBD DLC a Clio II 1.5 dCi Delpi DDCR 80945A ECU and
a VW Polo 1.4 16v MPI Marelli 4HV ECU.

Something I can't understand.
The dump from the Clio is only 40kb.
The dump of the Polo is only 896kb.
What is that? is that the eeprom content from the cpu of the ECU?

Here are the files, I will share it with you, maybe somebody can use that, I don't know...

[pankar]

You have read the cpu from the ecu that writes the operating program.
In some ecu, the memory is located outside of the processor like the Delpi DDCR.
In the ddcr the memory is in 95160 chip 4kb size and you must read this to make virgin the ecu.
Inside the operating program maybe exist the maps of the injection or the maps locate in the memory like the sirius 32 in 29f200 256kb.
In another cpu like motorola the memory locate in the cpu.
Each ecu has a different size of program and memory.
The dump from clio 40kb maybe is some sectors from the chip.

Hmmm....
Let's say, I wish to clone the ECU MJD 603 from Marelli which is in the Opel Corsa-D.
I have to read the firmware out from the original ECU and the eeprome?

Then I have to write back to the "new" ( I mean used ) ECU from another car.

How can I know should I read out the firmware through the DLC with the OBD connector or should I open the ECU and use the BDM type of reading/writing?

If I open the ECU from the Clio and try to read it through bdm should I get the same result of 40kb of some memory?

What if I wish to send the readout to a tuning company or person?
How could I know if I read the correct memory when I have no choice to select in Galletto what I wish to read or write?

Several years I worked on another field of electronic, where I used all days the flashers etc. but in the software for flashing I every time know what I'm read and what I write.

What is the option to repair a bricked ECU with Galletto or other tool similar to this?

If I flash back the exactly same file into the ECU of the mentioned Clio should the car operate as before the writing?

Or for what can I use that "UPC" Unidentified Program Code?

Lats say, is it possible to make immo off for my clio from the dump what I posted?
Is that file correct for that task?

I'm a bit confused now.

Thanks for helping...

Read the galleto's manuals for each ecu. To read full dump you need read the ecu in boot mode.

If I open the ECU from the Clio and try to read it through bdm should I get the same result of 40kb of some memory?

I don’t think so. 40kb is only the injection maps for tuning.

What if I wish to send the readout to a tuning company or person?

Only in boot mode you read full dump. Send all the dump.

If I flash back the exactly same file into the ECU of the mentioned Clio should the car operate as before the writing?

Of course.

Lats say, is it possible to make immo off for my clio from the dump what I posted?

For clio ddcr 1.5 only virgin stage in 95160 or immo off with can emulator.

Pankar:
Thank you very much for all the handy info's.
This is rely valuable for as who are at the beginning of this thinks.

So, I figured out lot of steps, with your and other's good peoples help.

This is my thinking how Galletto is working, I mean what is the logic of Galletto:

Galletto is a tuning tool.
This tool is oriented to read out the memory regions from the ECU
so it could be usable for tuning purpose and not for flashing bricked ECU's, but they can ( maybe ) do that too in boot mode or in BDM mode,
I'm not so sure about this, so please pros give your words of experience.

When I click on "Select driver" I have an option to select the car or other vehicle model and read them by the mounted DLC through OBD2
connector without to open the ECU.
In real world it looks like this:


Down in the 4. text box is written:
[DELPHI DELCO DDCR NISSAN/RENAULT] 'K-Line' (READ WRITE 40Kb) -FLASH 29F200BB-

What means:
ECU type: DELPHI DELCO DDCR NISSAN/RENAULT
Read/Write through the: K-Line
Read/Write: 40Kb
Memory from where are the data: FLASH 29F200BB

So, this means, a part of the data will be extracted from the whole memory chip,
which is the 29F200BB IC on the pcb of the ECU.
This partial data should be actually the map for tuning.
This flash IC have a capacity of 2Mbit, so the extracted data of 40kb must be the injection data which must be for tuning purpose.

In this scenario a bricked or a ECU cloning situation I think is not possible with this option of Galletto.
If I wish to recovery an ECU from a bad flashed content or a broken flashing procedure before I have to flash the whole data to the 29F200BB and not only the 40kb. Also I have to program the external eeprom too which is on this Clio the 95160 eeprom. This eeprom is not possible to read/write by Galletto.

But, if I go to "Tool boot" mode in Galletto, then I have a new situation:
I will take the same car, my Clio.


In the 4. text box, is almost the same text as before but with a huge change!
[DELPHI DDCR E3] 'K-Line' (READ WRITE 256Kb) -FLASH 29F200BB-

What means:
ECU type: DELPHI DDCR E3
Read/Write through the: K-Line
Read/Write: 256Kb
Memory from where are the data: FLASH 29F200BB

Actually, this means for me if I'm right does Galletto will read the whole memory
from the 29F200BB IC compared to the first reading situation through the DLC with the OBD2 connector.

My question is:
If I read with boot mode the whole flash content with Galletto, and read the 95160 eeprom with an eeprom programmer. After that, if I write all this back to
another ECU with the same platform ( same chipset ) would this be a good clone?

If I let say back up the content of 29F200BB with the Galletto in Tool boot mode, and if I change the flash ic with a new one, or from another used ECU and write back the backuped content to the ne flash, would this start the car as before the swapping?

Conclusion, if we read through OBD2 the ECU then we got only the partial memory for tuning purpose, but there is maybe an option through Tool boot and BDM to make some whole backup of the flash memories but not the cpu firmware.
Through this option of Galletto we can actually repair ECU's whit flash memory failures or bricked flash IC's by changing it with new one and flashing it with ori data's.
But! if there is a bug or something goes wrong with the firmware then we can't do the repair job. For that purpose we must have a cpu flashing device for that exactly cpu what we deal.

I wrote this for peoples who are making his first steps as I did it yesterday with my new Galletto v54 tool.
Maybe somebody can use my experience what I got few hours playing with ECU's and cars.

I'm also wait for pros to comment am I right of the logic how Galletto works and how that stuff with Galletto is actually usable.

Conclusion, Galletto is a tuning tool and not an ECU repairing tool, but it could maybe be handy to have this tool too in the garage...

My best regards.

Yes you make clone the ECU.

If I let say back up the content of 29F200BB with the Galletto in Tool boot mode, and if I change the flash ic with a new one, or from another used ECU and write back the backuped content to the ne flash, would this start the car as before the swapping?

That's right.

To start reading in safe mode, you have to do some changes in the ECU.
See the attached picture for ddcr.

The ddcr has Memories : 25080 and M29F200BB not 95160 who I had written before.

To start reading in safe mode...

What do you mean under

safe mode

?
Is that the boot mode?

I can see on the picture is a 1k resistor to ground.
I think that is some sort program enabled or so...

Thanks.

Yes boot mode i mean. Solder 1k resistor and after read with galleto.

If I make some changes in the data what I read out before, what I post earlier here for the Clio and Polo, should I correct the checksum somewhere in the flash IC content?
Actually there should be somewhere a checksum control algorithm in the cpu.
If the data is modified and the checksum is not recalculated that would ended up in error.

Is there some kind of this or no?
