Disable automatic CKS in some Tools

[OVERSPEED]

There is some way to disable automatic checksum when writing ?

Example: FGtech2 and galleto 1260 and Multec H

They can?t make it in the rigth way, there is some kind of trick to disable (exemple erase any dll or something like this ?)

[mexanico1971]

in 1260 I know that exist"s that dll !
and you can erase them !
but if you do not have the cks correct probably the car don"t work !

I?ll try today in bench...

problem is thar tool don?t make the cks correct... and car don?t start either, so better make cks with winOls, ECM2001 or even "by hand" (not dificult in Multec)

1080 NO GM AUTOSUM.
1260 YES GM AUTOSUM.
CHANGE SERIAL NUMBER 1080 IN 1260 WITH MPROG.
USE SOFTWARE 1080
NOT USE WITH ECU SOIC C256 Galeto ONLY KESS MAGPRO2 OR PROGRAM WITH ECU SOIC C256.

I?m the bench now trying some combinations between tools:

1- Save an original file with KessV1 (read with KessV1 long time ago) with cks DD66

2- Read With FGtech2 and 1260
they both read the same file, BUT it?s diferent from what I write

original file cks DD66
other files are DC66 and there is 4 diferent bits in the beggining

3- Opcom says it?s all rigth there is NO P1660 DTC (that means ECU "bricked" and car don?t start)

4- modify the file read by FGtech (DC66) correct the cks manually and save with FGtech

5- Opcom says no P1660DTC

6- read again with KessV1, 1260 and FGtech and the file is the same I Write with FGtech
(the tool didn?t correct in writing because I allready made the cks manually)

From what I know, galletto kills all the GM plants used here in Brazil, because it changes the recording cheksun
The one I use it without problems with it, is the M1.5.5.
The others, I do it with another tool.
