Which kind of relation are from cks to programmer ?

Im using CombiLoader v2, but this tool only correct CKS in the "maps zone" but the mod is for DECAT, and my DECAT file supplier say that not have the plugin for cks correct in this ECU. I see that u offer DTC delete service, may u can help me or sell u service.
Thanks.

In the .rar file that I atttached in the first post is a file [DECAT_v3_(CS corrected!).bin] already corrected by the CombiLoader Developer. May it work like example.

cks is corrected with genuine winols ,so i don't know how it is possible to calculate cks better :)

[Fogz]

I dont know if "better" but you can se if you compare the files that the correction is very diferent and is in the lines 28000 - 28020 and CB000 - CB020. Is like the cks correction is made by zones, because some files only need to be corrected in the first lines and others between the second lines depending what area was moded.
