guys since this post ? generic doubts write, I ask you:
I have read a Fiat punto 2004 1.3 mjet 70cv. when I open the map with the ecm to me two checksum errors when I open the file, then it asks me to register it in the database, and after that is the driver I rid? the other two times the error calculating the checksum.

my doubt ?: can I modify and write to the map anyway, so the calculation of the checksum of me would make it the Rooster?
what do you think?

you could do this easily, so the limit rewrite the original file where the checksum ? definitely right!

but these 4 errors (2 prior to the selection of the driver and the other 2 after) according to you, what you depend on?

Hello pitty,what are the dimensions of the file that you've read? The then post here?

[pitty]

Sure... here...? now that I realize it maybe ? bed terrible... ? of 2.5 mb, can? be??? it seems to me strange!!!

As you read?Via serial?I these machines make them bdm or write with mpps(when I'm not planing to leave the car), However, it also happens on other machines that Galletto v2 reads the file with dimensions that are not typical.

I have given you a look at the file and I think that then also write using galletto 2 .According to me the error of ceksum out because of the size of the file.

I have heard that among all the interfaces mpps ? the pi? not recommended for this kind of ECU... with a rooster read and write from serial port without problems, and I have not read of anyone who has had a hitch, however, with mpps just do a search on ******.

you can write the read file with chicken-2.5 mb I have read and written it takes an eternity? for? 80 min reading 40 min write and when you edit you can not use the drivers because? many times they are not centered well given the different size of the file, obviously this ? the street pi? long for mod the 6f3, mpps patch on muse dobl? and y..

[pitty]

damn... so this has to be changed in 2d. I hope I get in.

but if I read with mpps should I have a file of 2 mb then?
almost there I try to read it and then write it with the Rooster though ? not recommended. or I try to read with the Cock? bdm would be dismantling the unit. right?
