Forgive me for what may seem like a newb question

I recently swapped the transfer case in my unlimitedX for a rubicon 4:1 tcase

I want to update this on my superchips but have no idea what the setting would be.

It asks me for my tcase high ratio and tcase low ratio

My assumption was I would change the high to 2. The low to 4.1

Please forgive me if this is the dumbest question to hit the net.

 

High range is always 1:1. Only thing that changes is low. Well unless you got a suk the had a reduced high

 

This is what I thought.

So I would keep high as 1.


But for the low, it says 2.72
I'm assuming I would chnage that to 4.10?

 

4 is low range 4.10 is axle ratio for rubis

 

The stock setting for superchips when I had the original stock transfer case was as follows:

High range : 1
Low range: 2.72

I think this makes sense to me now. New case ratio is 4:1 old was 2.72:1.
