MagPro2 Advice on use.

[bart]

Should I use MagPro2 v4.2 to read and write the map of the Ducato 2.3 mjet which ? the treaty change these days in my other dedicated thread.
I would like to kindly ask for some advice...
According to you, to read and write without problems the EDC16 mounted on the vehicle, which speed? data transfer recommended:
- Minimum
- Media
- Fast
- Maximum

Also is it best to write "only" or "all"?

I ask for one last clarification: what is the button "Magp" which is on the right just above the button "Exit"?
Thanks for the advice!

[msport (exil77grande)]

then for the button magp I don't remember what the subtitle,for the speed, let that set, if you get problems in reading try them all until the law, and then remember to use the same speed in writing,to the mode at all or only data I would say to read the whole thing, and then write only the data, but I believe that in some cases, face still as he wants.

Thank you so much to both of you!

...for the mode at all or only data I would say to read the whole thing, and then write only data...

Given that the topic intrigues me: prativamente by only writing the data, the programmer goes to rewrite only the part of the map, which lists only the plans that affect the performance of the vehicle and usually modified by the preparatory?
To make there? compare the map in the ecu with the one that we are writing to, and then transcribe only the parts that are different, or simply the people that made the hardware programming has included specific addresses for each ecu and the programmer rewrites automatically only those areas of the map?

exactly only writes the porziona of data that need to change.

[giarras]

in k-line you always recommend mode? slow x the rest ? as it says msport.

[bart]

Do you know if the portion of data rewrites is determined from time to time by comparing the map present in the ecu with the one that we are uploading, or if ? been established a priori by the manufacturer of the instrument box (MagPro, Rooster, etc...)?
I ask this to understand if there is the risk that the instrument, in the process of writing with this mode?, to omit the regions of the map that have been modified, or if ? a doubt non-existent.
Thanks!

[msport (exil77grande)]

you can change what you want, however, in mode, only the data will eventually write a portion of the map.

[bart]

Then, if the portion of the map is to be rewritten ? fixed, c'? the risk is that if ? been modified to some particular value, or if the person who designed the device ? forgot to include the address of a region of the map "useful", it may happen that some data may not be transcribed?

Also in this mode? I imagine that it is, however, essential to the checksum, and that the force of things must be done by the software of the device write?

What? the advantage of this mode?: only the reduction of time in the writing phase, or it eliminates or at least reduces the risk of locking the ecu?
Still, thank you, msport!

[magi1984]

by writing only a part of the maps ? pi? easy to save the ecu in the case of a block without bdm
the checksum is to be calculated, the calculations with ecm titanium, or other sw type winols, or the calculations with the read and write interface, but must always be calculated.
tip: connect a battery or a booster to avoid voltage drop, do it always, often the cause of a lock ecu ? a voltage sag in the process of writing

[bart]

Thanks magi1984 for the clarification!

I tried today, following your advice, for now I'm limited to reading.
I have noticed for? for this specific model of ecu ? can decide whether to read all or data only: the decides on the tool! So I think that in this specific case, read and write everything...
However, 1000 thanks to all three for the comprehensive explanations: I will definitely be useful with the next control units
