Insights on file ORI read in from the serial port and BDM

[zioweb]

Hello guys, I have a couple of questions to ask the attention of the experts.
I have a ecu Mjet 6f3 of the Ypsilon. Read correctly with MPPS V12 giving me output to a file from 1Mb.
Subsequently, ? read also with the MAGPRO restoring the backup to the micro and complete flash-2mb (then equivalent to the BDM backup, right?)
I know the procedure to cut the file to 2Mb and make it "digest" from the MPPS in writing but I don't understand one thing: for split file you need to do the checksum, or I can give you a meal directly? Remember that the V12 on these units do not automatically corrects.

Another important thing: the two files to 1Mb (the one generated by the serial reading and the one generated starting from the file 2Mb) must be IDENTICAL in content, or they can differ? I do not speak of the maps I have are the same, but in other parts of the file.

In the case, to verify, do you have any GOLD of these ECU's bed in the serial and also in the BDM backup cos? to cut the file to compare them?

What I have in my hand are two identical files in the maps, but with several differences from the met? in the file then...

then the file 2m read from the mag definitely not the same as the file that is read in the bdm (backup), albeit with the same size and you can see if you're comparing the two files to see which one has a area straight to ffffff and the other in that area, however, has data,for the council saw that mpps does the ck in writing, you should put the driver on the ecm to cut the file and save it by calculating the ck so go is the most peaceful.

ok, will prove? this thing back up in the bdm, who will be? surely as you say.
For the checksum, the problem arises when the software you use will not calculate the checksum, as some of the drivers for ecm precisely...

there are programs that calculate the cecksum as winols and ceckcorrecctor up-to-date, for otherwise there you will find the marelli, however, from what I remember of the mpps v12 when you can not calculate the cecksum,usually in the c'? the key check there clicking over and asks you to load the file ori and then the modified one,corrects the cecksum and asks you if you want to write

if in case you have a file that is read with mpps of 2mg and write hangs, can you? riutillizare that file, editing it just in case, to rewrite it in the bdm? or c'? only need the bdm backup?

let's say that it depends,first thing's first, you should try to do a force write mode? recovery ? the best solution without turning off the picture,then in the case you do not succeed then we turn off the picture and try again,in case you do not succeed, then you must open the ecu and read the file in the bdm,then you need to cut the file bdm to the met? and save only the part that refers to the tables,which must be replaced with the tables that are read in serial,or something even more? simple copy those read the serial on the ones read in bdm,or find a backup of the flash and scriverglio,but this process applies to the bosch

I understand...you can read the eprom seen that the flash ? cleared and cut, right?

correct.

mpps does not read from 2mb, but from 1mb only the 1.3 mjet. If you want to check the file 2mb bed with magpro in serial on the 1.3 mjet with the bdm just find the backup of the software version that I read and I see I found I did not.
