Just to further clarify the "WARNING: Checksum is disabled!" message means.
Some hand held tuners did not or could not update the checksums correctly when they made changes to the ECM. To compensate for that they disabled the checksums in the ECM by "damaging" the checksum calculation routines. When EFILive re-flashes the ECM and when the hand held tuners supposedly "return to stock" the area of memory where the checksum routines are located does not get updated. That means once the checksum routines have been damaged the checksum in the tune file must be left disabled otherwise you will set the MIL.
If you did click on the [Update Checksums] button in EFILive to correct the checksum and flashed the corrected file back into the truck or if you simply flashed stock tune that had its checksums enabled back into an ECM that had been "returned to stock" you would set the MIL.
For Cummins tunes, when the checksum is not disabled (i.e. for a stock tune) the button changes to [Disable Checksums] to allow you to disable the checksum so that it can be flashed into an ECM that expects tunes with disabled checksums - i.e. ECMs that have previously been hand held tuned and returned to stock.

The tutorials open correctly from the tune tool, but in the scan tool, when I select scan tool tutorial the first time, I get "Bench Harness pin out." After that, any tutorial that is selected opens the "Installing an EFILive Custom Operating System & Using the 2/3 bar features of EFILive V7" tutorial.
I wanted to see if there was something I didn't remember about PIDs or PID groups...
When I open the scan tool I can't select any PID group at all. I have the controller set to CMB and list to "all." If I open an existing PID file it works, but I can't do anything else. It must be something in the new download. I haven't had any problems with the previous version. I'm going to uninstall then reinstall the new version.
thanks rich and paul, that took care of the files showing up. my other problem i just ran into is when i make changes to my latest files, save and go to re open the file, it will not allow me to. they are still in my documents but the tune tool says the file being opened is not a valid efilive file. does this have to do with the checksum? these are off a stock file. just to verify, i made a copy of one of the stock, untouched files i had, made a small change and saved. same thing. invalid file. is there a way to restore these files? i uninstalled the new version, reinstalled the old version and it would not let me open the files either. i've got the new version installed now. thanks for any help.

Can you please send me two copies of the file?
One of before you modified it that can be opened and one after you modified and saved it that can't be opened.
Send to paul@efilive.com
Thanks

I'm not sure what is happening with the tutorials showing up wrong - it works fine here. If you can provide any more information about the problem it would help.
Have you got the "Supported" check box checked? If so the Cummins PIDs (which may be flagged as unsupported until you connect to a vehicle and validate them) will probably not be visible and that will stop the group selections from happening.
So try unchecking the "Supported" checkbox. And when you do eventually hook up to your truck, run the "Validate PIDs" option to take a copy of the valid PIDs so next time the PIDs will show up as supported even when you are not connected.

i cant even open it now but i'll gladly send u the file itself. thanks for your help. email on its way in a few
good deal. still want the file?
Dumb question...by uninstalling the current software...will I loose all my saved dashes and pid lists that I have self defined??
If so, how can i save them and get them onto the new software??
