r20 Wont load custom tune

[Mullens]

I have a cmr tune I've been using successfully for months. When I downloaded r20, I get a message "Does not support CALID 05030232 custom tune" and only gives me the canned tunes to load. When I revert back to r19 everything works fine like it did before. I have an 06 SRT8 with the same CALID I've always had. Another member also reportd the same problem. Any thoughts Mike?
Thanks

Load the custom tune in after tool has taken a backup.

I'm a little confused about taking a backup. In r19 when I went back to stock, the tuner saved the original backup as always. I even saved it to my PC to see if the CALID had changed, which it did not. Is that what you mean? The reason I ask is because I never have had to do anyhing different with the previous revisions. I guess what I'm asking is why is r20 differnet than other revisions when the CALID has not changed.
Thanks

Here is what you need to do.
Restore backup.
Update to 8r20.
Allow Predator to read backup file (either install canned tune, or unplug after it has saved the backup when it offers "Install tune/Modify tune".)
Now, load the custom tune to the Predator, and flash it to the car.

Thanks

Will do Mike. Thanks!
