Hello.
I did changes in my stock ECU 4B0906018DF (I changed some addreeses for Launch Control)
The ori file is calculated OK:
Code:
c:\me7>ME7Check.exe "4B0906018DF.ori"

Looks like a bug in me7sum. You can run the file through me7sum again, it should fix it.

I'll look into why it requires being run twice.

Hi z1ck do you have the 95040 OEM dump from that ECU?
Thanks,
