Found the linear-fill . it seems if you move the left hand side repository tree it causes the linear-fill to be hidden when window is not fully opened .
Just noticed when I saved the Original tune that was read form the PCM , before flashing with Custom OS , to another name it changed the VIN number .
Checked a old .tun and saw it as well has a different VIN number ?
Also when I did the read of the Custom OS back off the PCM data was still present from another session of Custom OS .
Why is old Custom OS data still in PCM after full re-flash ?
