Yellow box calibrations

Propably not the first time this question is asked here and for that I apologize.

I'm wondering if there is a known setting for the yellow box on stock tires and 4.57 gears?
Trying to prepare how much work I will have to do when I will install my gears.

Calculate the % difference between the stock gearing to the 4.57s and use this as a starting point. It's just math.

Ahh ok.

So the difference between 4.57 and 4.1 is roughly 11.46%

That means the setting would be 1010010, correct?

Ohh wait or is it 0101110

however, if you want to dial out the natural error of your speedo and tire variation, you will have to get paced by a known calibrated source or get shot with a radar device.

Or borrow a portable GPS ... works great.

We had a little discussion on this some time ago. If you do the calibration on a level road, then you're likely fine. However, it's questionable whether or not a car based, "civilian" GPS device will measure distance correctly if there is a significant elevation change. For example, if you measure going down or up a steep incline, it may not give you a correct reading. It may only give you the horizontal distance travelled and base your speed on that.
