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!

I'm getting a dialog box telling me

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

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.

Btw I'm not datalogging just editing alone.

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

Silly me, I was thinking EEC V tach output, not direct to coil for tachometer sense

Thank's, it's much better now. Question. I have both CABHO and CZJAL on the chip, I noticed that the CZAJL shows approx 10% more RPM thru the datalink on my old Snap On 2500 scanner, something to do with PIP settings? I checked it several times to be sure. Doing an EDIS conversion on my 89 gt with that strategy and ecm and wonder if that's going to be an issue on it.

Thanks it's much better.

Too long to complete the shift the timing is fine

Thank's
