Alfa mito 8f3 - after writing the serial part without any errors and after a little bit, not more

Hi guys, yesterday, I wrote a myth 8f3 with the kess 5.017 - 2.47 and after having written and followed all the procedures, turning on and off the framework, the machine regularly without errors. do a test drive and all ok. then once off the car, we put them on the bike and nothing, the fuel pump that is not starting despite the immo was ok recognizing the key. then I do the procedure of unlocking ecu with kess and says completed, but still not part of it. in engine diagnosis, there are two errors, one eprom hurt that you delete it safely with multiecuscan, the other speaks of the ecu protection (safety) that is not clear. to quickly resolve I have not transcribed the error codes unfortunately. I make another write up with a second file, and the same thing happens. We have put in motion, this time a dozen times and done a few miles without problems, then we stop and after a little we put them on the bike but nothing, same errors. So I decide to put the file ori and for now it seems ok. The absurd thing, and that I never happened is that the machine most times.. and then nothing more and has no errors except that of the controller in protection, but then protection from what ? that? saw that part at the beginning

hello, it is found that with the file ori and the car is fine, the problem is the wire mod, very likely, or you have touched the bit that must not be touched or you have exaggerated with some of the changes and the ecu can't manage them and gets in the security, the cks have you calculated before write mod file?

Hello, the only changes are the dpf and egr. The checksum has calculated the kess 2.47 fw 5. 017.

what you did with the luca stanca and egroff? by hand or with the sw, you're sure of what has been done?

Are files that have already been tested. Maybe tonight when I go to place the file. I might eventually try to write with fgtech v54. Some 8df I've done with that and should go well with the 8f3

it is a bug of the kess 5.017 that on mj8f3 errs on the cks. Just write with fgtech and you will be fine. It happened to me more times on power units that begin with the number soft 1xxx...

Here is a file without DPF and EGR which I loaded and which is the game, but then after several ignitions that are not wanted any more and I had to put the original file. So it may be a problem of the checksum is not calculated by the tool. however, it is strange that both game multiple times and nothing more. I would like to avoid to open it, and the alternative is to fgtech v53 that, however, did not specifically 8f3 even if it should be like the previous 8df. The file is correct ?

I calculated the checksum with winOLS, should be corrected. Could someone verify this ?
possibly I could write the file always with the kess visa, which does not correct the checksum ( or corrects it in the wrong way ? )

hello, when you ask for advice on a modified file you should always attach the original, you can't expect that whoever controls it, should have it or go looking for it, however, your file has been modified, but I don't know what the sw, and very different from the luca stanca classic on these ecu's, they have eliminated many things (dtc) and also the egr and done in a different way from how I know, but surely this is my problem, the cks on the second file is fine but unfortunately the kess you can modify equally, I have never had problems of cks with kess on these ecus, in each case write the file with the cks correct then you re-read it and check it with winols and see if it has changed in the wrong way, I do not think is a problem of cks in every case.

Hello, sorry, I posted the file ori here, I thought of having it attached . However, it is what is in the post DPF alfa mito, which is in front of this.
I will try then to write it with the cock v54. Although short-I will take the " I " terminal, at least I will not have problems with the marelli

remember that I terminal, do cks on these, fix it, always with ols.

Update on the status of the vehicle.
Yesterday made writing after remapped to have more thrust and calculated the chk with winols and all went well. the kess apparently has a bug on the ecu and does not calculate anything
