    Default Saved tune in v8 now won't load in v7

    I downloaded a tune from a stock lmm 2007 and wanted to open it up in the v7.5 tune program just to snoop around and it won't even find the file to open it.

    Is there a program or converter to allow the tunes saved in a v8 to beable to be loaded in the v7.5?

    Do you have matching installs for both V8 and V7 ? In otherwords you can't have an old version of V7 installed if you have a newer version of V8.

    You downloaded it as in 'read from the truck' or a file you found on the internet?

    You will need a later version of V7 tunetool... try this: Update-Oct-5-2014

    ( you will need to updater both V7 and V8... and also V2 firmware... and also V2 BBx configuration )
