Hey guys,

Lately I have been having trouble with my speedo calculator. I have the latest version of everything, and when I click on the speedo caclulator and type in the tire size, it doesn't automatically jump to the adjust %. It used to do that before. Even if I click on the tab for the shift point correction the adjust % is 0. Has anyone encountered this or do I have to do it differently?
Please help, speedo adjust is big business on the Duramax since it can't be done by the Tech 2. Thanks a lot.
