A greeting to all , I am a beginner and I'm trying to figure out how to scodificare part of this ecu 9gf.t7 Fiat 500 1.2 euro6 HW MM9GFHWN01 SW 2L12FAAM to be able to mount on a different car , I read the ecu with kessv2 and I got a files, 2.00 mb, thanks in advance to anyone who can help me/teach
Always on this ecu I can add a question by opening the presence of a memory 95640 that a well-known manufacturer of emulators change in the two addresses, my question is 1 by reading with the kessv2, the files obtained is compression of this memory? 2 if in the above addresses port all on ff would be the right procedure for rinverginare the ecu thanks to anyone who can help me
if you can read the e2p 95640 dev be pass the file you do it the virginQuote:

Thank you first for your availability, the files that I got from 2 mb with reading the obd also contains the e2p? Or do I have to open the ecu and only read the e2p, it is precisely on this memory I've seen that some manufacturers of emulators, modify Some strings, I wondered if it was enough to put FF right in those points for virginal the above-mentioned ecu, I ask you this to understand and open evenings at its best
Unfortunately I can not( do not know)to post photos of the change of e2p is what I said
with kess the file to 2 megs that the laws does not include the e2prom, that you should dissaldarla and read it on the bench.
Thank you for the elucidation, I ask if I can read with tweezers or is there a difference?
better if the dissaldi...
I find the various discussions on this fact in order to unsolder or read them with tweezers if someone experienced can explain me, however, in the meantime, I open and read this e2p
remove always, reading it with the caliper on the pcb, you need to understand that and connected to other things on the pcb itself, then the read can be altered.
Thanks for the response I will do a reading with both the tweezer and soldering the memory so as to see what differences there are I wanted to do also another question I noticed that with the ktag you can read some eeprom may be advisable when the device allows it or however, whatever, and always better to weld and read type, with Car PROG
when the tool gives you the opportunity to also read quietly in the e2prom, and take a backup of the ecu.
Thank you for the response ugoboss, I tried to read this memory with the k tag , doing the backup and then read each eeprom 95320 modified with immo universal and then re-written but, unfortunately, from the diagnosis, the error code is related to modifying the ecu a edc16u34 Seat, for this, I ask how to calculate the checksum of this eeprom is to first rewrite them with ktag I noticed that immo universal does not speak of the checksum after editing the files but it says to check it, but how? I have noticed that software like Meucci make the checksum automatically, and however I can confirm that the reading with the tweezer not on all ecu's you can do scontrandomi with this edc16u34 I've noticed that on this you can read it with the pliers or with the tool or desolder the eeprom, I thank anyone who can teach me to calculate the checksum for this eeprom or in general
expect that I'm missing, here were talking about an ecu marelli 9fgf, now you talk about a edc16u34 vag, not to change topic on the same discussion, if you want to open another and post the new problem, in any case, usually when you immoff on the eeprom I do not correct myself, but there are sw that you do. on many ecu when you immoff in the diagnosis you have the error on the immobilazer but and normal.
To be able to do a partial, you need to read the e2p with a programmer such as I-terminal for example... and then you rivergina the code and rewrites it in, and how the mountains takes up the new code.
I apologize to Ugoboss for the slight turn of topic that I made on my last post, and I thank him ,and ask the dj piex if the riverginatura that I want to do as you can do without the software if you know the hexadecimal values to change on the eeprom of this 9fgf
the values change from sw to sw, and I-terminal-for example, an ec-specific function to do it, or I hand, I make attempts at clearing the zone a little at a time and testing where is the right test after test... I reset an area in the e2p and write it, and I try, until I find the right area..Quote:

Thank you Dj piex for clarity , and I answer , I have understood the system and I believe that it is difficult for me to even why should I unsolder and solder several times the eeprom or solder temporarily a port eeprom sop spring to do the tests , however, I try to read it, desolder the eeprom so in the meantime, on these ecu understand that there is a difference between reading with the caliper and dissaldarla already if there were differences with the caliper do much before,however when we speak of the clear you intend to put FF in hex? Thanks again
I wanted to post the readings of the eeprom who can help me I do not understand how to do it
