For those that would like to try it, I found this from Google search. Seems like you need to use Test 19 to unlock the tests, then enter into Test 20 and then change the correction factor.
I haven't been able to change my MPG correction factor through the instrument cluster; has anyone else been able to? Test 20 does not indicate any data with the tests locked or unlocked. Neither am I able to access sub-menus to input data. Has anyone else tried it with success?
