Ile give you a help full tip.
as soon as you have a cam you like on what ever car.
from the default cams check the differences plus or minus on X then Y then Z
and when you have the differences apply them to all the other cars.
Do all X then do all Y then do all Z on each.
Shouldn't take you any longer than 20 min to do all the other cars that way, except merk and redbull they need moving forward .2
You can pretty much guarantee every cam will be exactly what your after then will save you tons of trial and error because your using default as your datum line. for example
if you have to move forward .3 but its already on -.1 it will be +.2
+6
+5
+4
+3
+2
+1
0
-1
-2
-3
-4
-5
-6
Hope that makes sense.
good job though keep it up.
