Thanks to Nef i made a basic tuning file in winols searching the maps in my ori file, i use a MPPS 13 to read and writing.
I Write diferent version of my tune and when y was writing the last time it fail. The fun star working, i was in panic i just tried to write again the file. I had good luck because it wrote fine and the car work very well. It was tho month ago.
 Now i made a reading of my ecu again and a read a binary file of 848 Kb, when always read 2 Mb. The mapPack from my ori file dont work in the 848 Kb file. I think something happend when fail te writing.

Can i tried to write again a 2 Mb file?
