one or more incorrect segment checksums?

[dbaxter_ss]

I just got the new fuel rail fix and superchips tuner (tune) from magnuson for my GTO.

After flashing it with the superchips tuner, I pulled it immediately off to see what was done and make appropriate changes.

But once it was done pulling the tune, and each time opening I get a popup.

The calibration file c:\blah\file.tun contains one or more incorrect segment checksums.

EFILive cannot guarentee the integrity of the file and will not allow this file to be reflashed into a PCM.

Quite common with some aftermarket companies, not real good though, VERY bad on an ETC car.

I'll take a look at the file for you (except the link isn't working).

Cheers,

just right click, save as and rename at .tun

I am going out this afternoon for lunch and trying again, sure hope this is not a version thing also? z06 speed limiter issue in tuning section also acting weird
