I read via OBD the ECU of a EDC16C9 and I noticed that the first part of the file that is read with MPPS ? pot up at the beginning of the maps, while with Galletto 1260 that the first part of the file ? at all flat rather ? very jagged. The part of the maps that are real instead ? identical in both files. ? normal or one of the 2 software has bad bed?
very likely that one has only read the tables and the other is read as a whole.

At this point I can think of some questions...Originally Written by ugoboss
Seen that, for example in this case, MPPS not ? able to law nothing in the first part ? correct to assume that I can not? even writing in the first part, and then leave? unchanged the area on the ECU?
absolutely... the data base (that is, the first part of the map) MPPS not ? able to read, let alone write it, and then leaves it unchanged
Then you should always read and write to the file with the same sw to avoid unwanted changes?
If I was with a Cock the file read with MPPS I guess I'd erase something..
? always correct to use the same interface to read and write, same thing with the file, if you read a file with an interface ? preferable to rewrite it with the same, but I can confirm that mpps on edc16c39 fiat group where you only read the part of the map, if the by the to write a file to a full bed in the bdm you wrote everything correctly, it puts a little more but you write it out.

Let's say that if one has the backup of the BDM, pu? fun to do all the tests you want, otherwise it is better not to risk it.
Example: I use mpps, I don't have the bdm backup why? I did not want to open the ecu, in the case of the block are aware that I will have to open the ecu to do the bck bench and rebuild the file in order to set in motion the machinery. If I began to insert variables such as different programmers might be all pi? complicated... I don't know if I have explained?
The fact that you can write in the area in which not the law ? very interesting, I hope to do only with the file that is read in BDM and anyway I would be curious to understand how it is possible.
At this point I wonder.. since the interfaces to write to memory addresses that are well-defined in the file ? can write only a part of the map (e.g. only one that includes the modified part), cutting the file in an appropriate way?
(e.g. change the curve of the EGR, cut the file before and after the changed values and write the file that will be? of a few bits.)
Absolutely, by inserting too many variables you lose control.
I ? clear that the read/write BDM is the pi? safe, ****llo the software I intend to, since physically open the ECU and handle on the inside ? much more? delicate connect a cable to the OBD! Made a little practice serial I would certainly like to go to the tour, I read that the pi? versatile and reliable Kess v2, Gallo v54 and ...BDM 100?
with the kessv2 not work at the desk to open the control unit (bdm and j-tag) for the k-tag
