Custom Tune Edit help

[cajunboy2208]

I am going to mess with the timing and stuff.
I loaded the custom tune, and then went in the timing.
And it just says 0 on it.
I checked all of the other functions, such as shift points and stuff, they they are all not set either.
Is this normal?
Should I still just set it on the +1.5 save it for the timing.
And then next time it loads it will be set back to 0? Or will it be at 1.5 now?
Very confused on that.

Also. I did notice that my gear ratios is set to 3.73
I have 3.55 gears... was wondering if this is an error or did Bill accidenty insert 3.73 for me?
When I revereted it back to stock, it read the correct 3.55 gears, so this naturally worried me that he might of inserted the wrong value, and now my odometer is all effed up.

Not sure if I was clear on all of that.
I just figured it would already have values set in the custom tune instead of everything being at 0...
