Flashcal... Axle Ratio

[JK'AJUN]

What should I put for the axle ratio on my Flashcal? I have the tires set at 32.75"

My Jeep is a '11 JKU Automatic 3.8L

Here's what it's set at now:

I didn't adjust my axle ratio. Curious if I should've now. :thinking:

If you haven't regeared you don't need to put anything. It will read factory from the computer.

Your computer doesn't read the regear which is why there is an option for this.

That is why I left it alone. Thought maybe I missed something. Good call!:thumb:

So it will adjust the shift points automatically once my tire size is entered?

 

[sean.m.adams33]

Yup. Made a huge difference for me.

Yes. Your axle ratio has not changed. It will adjust speedo and shift points with tire size. Unless you have a manual then the shift points are on you.

Thats what I needed to know... I'm still new to this. Thanks!
