Hi, I'm having an issue with checksum when saving the file in Tunerpro. Even tried again with fresh downloads from the site and updated Tunerpro.
Whether or not I make changes to the base tune or not it gives the same message when saving the file.
I'm obviously missing something here, would anybody care to offer an idea? Something to do with datalogging?.
Thanks

Btw I'm not datalogging just editing alone.

Hmmm, I guess nobody else has this problem. I open the untouched file to look at it and cant save or exit without the checksum error message. I'll just keep trying maybe I can figure it out.

No idea.

I've had tunerpro calculating the checksum correctly for about 6 years now. I've never had a checksum problem since.

what xdf version are you using ? what version of tunerpro do you have?

I'm using tunerpro 5.0 build 9332 with bin A9L2_21021 and xdf GUFX_210129 from the site on Windows 10 HP laptop.

Everything looks normal otherwise, I did some editing and it seems to save all the changes but it probable wont work if the checksum is incorrect, correct?

Thank's

how do u know the checksum is incorrect?

I'm getting a dialog box telling me

The solution was to place the xdf into a separate folder a little odd since other ford and gm xdf's did not need that. Whatever works!
