Was trying to install OEM tune to my 2005 Dodge Magnum AWD R/T 5.7 Hemi, but i always get Restore failed. Parameters axle ratio.
Error etc... and reboot. No previous tunes with other programs. Worked fine over 4 years. Done uggrades etc.
Wanted to test i3 on wife 300C, but cant...
Could the error come, because i have AWD and AWD has 3.07 rear diff ratio and Diablo has only 3.06 etc.
Restore failed. Parameters axle ratio.

Re: Restore failed. Parameters axle ratio.
go to the quick adjust menu and select restore all quick adjusts, then if that works, do the restore tune and it should go through as expected.

Did try that Quick adjust, restore all.... But, it stops to Error, axle ratio. 
And did try normal restore, still Axle ratio error.
