HI
I have problem with Atra H delco mt 35. I've read flash using kess and at now i have file 1024kb. When i want to program back i have info that i have incorrect file size. Flash in to ecu is 29bl802 that is 512kb. Anyone found a solution to this ?

Did you mod the file you want to write back? Has it the same kb as ori? Kess does not calculate chksm.
Or you want to see if you can write the ori file back, only?

Yes, mod file. Ori and mod is 1024kb. I calculated chksm with winols.

You could do it on external programmer, like minipro tl866.
