Different file sizes ori and mod

Hello, and sorry in advance for the stupid question
I downloaded a kess some maps from different machines, and are normally 2048 KB, but me ? happened to find them even by 1536 KB, can???
As ever???
Thanks
Marco

Depends on the ecu that you read.. not all are the same.. c'? the one with more or less flash, that you read micro+flash, that you read only flash etc depends on the type of ecu!

Thanks lupo1
The same car, the map ori 2mega map mod 1,5 mb....
Nissan Juke

But the mod you made yourself? what car ? and that the ecu mounts? however, not ? normal ..

Excuse the lack of information!!!
I have a Juke 1.5 dCi with the ecu sid 305, a year ago I did remap the controller to be a professional, I have also disabled the Egr and controli dpf, emu has given and a copy of my map ori.
Now I started to try and map and my cousin who has my same machine wanted my map with a kess v2 I downloaded my map changed and then I've written about her, the car goes as well as mine.
By checking the two files I realized the size difference!!

Could it be that the gold that you gave was a bed in the bdm, or took it from a data bank. The gold of that of your cousin you read before you change it? What are the dimensions?

Read with galletto in the obd in front of me!!!!
My cousin was equal to my changed!
If I try to read the map gold with titanium recognizes her immediately!!!

If ? a 8f3 as you say, it ? a virtual reading.

Here is what comes out of my ignorance!!!!
What ? a virtual reading???

some of the tools, when they can't do the reading, obd, do id and they give you the files they have in their internal database, if they have it.

Okay!!!
Now I understand it!!!
Thanks a lot!!!

Resume for new information, the maps have different sizes why? the kess reads files from 1.5 mega and cock 2 mega!!

On many ecu?s you can not read the full flash. Each flasher read maybe other size and fill the nor readable sectors with FF

Translation ****** for someone like me who chews very little English
On many ecu''s not ? you can read the whole flash. Each indicator read perhaps other size and insert the readable sectors n? with FF
