I don't know why you try to modifiy/erase adaptation values and DTCs. Test it.

Thank you very much.
I tried it on another example but somehow I have a Problem with checksum here, because when I increase B2FB by 5000 it gets one Digit more ? So for example F9FB is +4700 but how to go higher, as I Need +5000 ?
Line to Change is A0 FF B2 FB, A0 gets 50 but I am not able to calculate the checksum, can anybody explain how this works on this example, file attached.
Thank you

Hmm I am confused now, there is "when you see A0 in 0x000 and 0x060 / 0x070, then change A0 to 50 and not calc the sums, change it to 9E"
And if I want to correct checksum its not possible as I cant increase B2FB by 5000, can you please help me one more time and explain what I am doing wrong ?
Thank you

TC1767 when you decrease A0 by 50 you need to increase checksum the same amount. |

Your checksum according to your original file is 0xFA41, so if you add 0x50 to that it would be 0xFA91.

Thank you for your answer but you used the first file posted, this was already solved. My original checksum is B2FB and I cant add 0x50 to that. |

Ok, still wrong though... Checksum in that file is FBB2, +0x50 is FC02.
