can change the sw?

Guys but on power units, the sw can you? change maybe putting one another?
for example... on my Big Point (or crying is not understood well) I have a Marelli Hardware Number: IAW5SFHW300
Marelli Software Number: 0813L45 and I would like to put the software of the IAW5SFHW300 with software 2103L65...
With what and how you read the ste units?
With mpps v12 you can? at least write the obd?
I've read that are sent in the recovery, but ... are sent in recovery and after connected drive and read from the obd? or all over-the-counter type with the fgtech v53 or similar? give me clarification about?...

Thank you in advance...

these operations via the obd does not make
on some ecu can you? also change the sw through a complete rewrite in the bdm , but you must first be sure that the software is compatible with your hardware.
since this information is not so? spread ? a good rule that in every electronic control unit will re-introduce the original sw.
there are lists in the house of the builders where ? indicated for a certain hw hw control unit such as the sw it can? host continuing to operate.
in general, it is necessary to consider that the sw is used to switch the motor but also to control the hw of the same unit, then ? it is linked in an indissoluble way.
changing the sw usually do not do damage, only the control unit does not work on the pi? as you would expect.
you restore everything by reprogramming the sw original, complete.

having a file ori of this unit, and by remapping all through ecm titanium:
1) can I write the file processed with mpps v12 via obd??

p.s. mpps v12 allows me (I've seen it in men?) go to options read and c'? a voice where it appears complete(kline):
2) for the absurd, I could use this programmer to read to tour?

if you read with mpps, you have to write with mpps
if you read in the bdm and you want to write with mpps need to split the file based on the car type, the multijet read in bdm, the file you get from 2 mb if you want to write with mpps need to cut it from 1 mb

mpps law a part of the flash
bdm reads the entire

zullo is talking about a gasoline!!!!!

I and my ecu do I do with the piasini!!! so I go to god!!!

zullo has said very well, he was just using the example of carlo ;)
I in this case, I can't read, why? my interface does not allow me to read this ecu, maybe I should put the resistor to get it to the recovery/modeb ? I have not tried, but before doing so I would like a pattern, a guide... someone who tells me how I have to do and if you can? do... only cos? to talk about it, I can not figure out how to do it,
then I would like to understand understand if I find a file ori from 448kb can I change it from the ecm, and write it in the following with mpps? what? the procedure?
I like the instrumentation, I have only mpps v12... on these ecu with mpps v12 c'? chance? to move in any way, at least in writing?...

I thought I was the multijet carlo sorry :confused:

I only bench with piasini putting in the boot with the strength|!!!expect someone if made in the serial!!

no zullo ahahahah :D miii confunsione ahahahha :D ? grande punto 1.2 petrol 65 hp with:
Fiat Hardware Number: 51780240
Marelli Hardware Number: IAW5SFHW300
Marelli Software Number: 0813L45
Fiat Identifacation Number: 5SF3M1
Fiat Iso Code: 0D07D504C2

in short... what we all know as 5sf3.m1 hw300 :) I would like to map it but I am having difficulty? not for mapping but for reading and writing... :)
