I found auto scale can be wrong or I'm missing something.
Why in stock file current gear ratio is different than calculated?
let's say 2004 corvette, I belive there is 3.42 installed, stock values:
Mile 31*027
rev-trans 12.6836
ratio 3.42
trans rev 2446
calculator says
current: 26 and 3.42
calculated 26 and 3.15
When I enter new as current, so 26 and 3.42, then he rescales speed and
rev-trans 11.6953
trans rev 2652
When I enter new as calculated so 26 and 3.15 then nothing is changed in tune except ratio that is changed to 3.15.
If I type similar data in Bluecat software, I get speeds close to 3.15 and they are similar to this from factory tune.
Could be that in tune factory speeds are not adjusted? Or they don't need to be adjusted because if only ratio is changed he calculates it self?
