Checksum correction Denso ECU

[Cardoso85]

Hi guys.
I have a 2008 Astra H GTC already modified.
When I bought a Kess, I decided to read the Denso ECU of my car, but when opening the file in WinOLS, it gives me an error, with no checksums available.
Recently with the help from annother user from this forum I was able to modify a bit more the file. He raisened some values and I tried to turn off the DPF.I opened the file in WinOLS to correct the checksum, and again, with no checksums available

Can anyone help work around this problem?

I'll Leave the files attached
Original (the one from the car) and the other one with raised values and hopefully DPF off.

Kess does checksum from original file when writing. just write moded file and Kess will ask for original file,select the original file. will fix checksum.
