Quadzilla adrenaline transmission slip


Recommended Posts

47re for trans and for tire wasn’t really sure on what size to put  I’m running a 35/13.50 I looked on the page to see what someone was tuning said he had a leveling kit with 33 think it was in the 90s so I went a couple numbers up and I looked up in the axle tag for the gears  I can look when I get off and let you know the 

numbers for sure

Circumference... 109.9" roughly.

 

3.55 or 4.10 are the standards. 

 

Just for fun the 245/75 R16 I'm running is 95.7" for measurement.

Here are a couple of sites; one for tire size comparison and another for gear ratio changes with tire size.

 

  1. https://www.discounttire.com/learn/tire-size-calculator 
  2. https://tiresize.com/gear-ratio-calculator/

The quad needs circumference  as 35" is no enough to calc the slip %

Okay will do  and I have a ? On the tire size how do you convert that to get the right number

Circumference = diameter times Pi

or in your case

C=35(your tire size)x3.14(Pi)

or as stated above...

Its nice to know the math behind the answer so you'll know how to calculate it again if you change your tire size :thumbup2:

The quad is saying that the transmission slip is at 100% but transmission seems to be fine  no problems 

 

Good information above, but an important piece missing. If the number wasn't accurate, yes, your tire size and gearing settings may need adjustment. However, where are you viewing this number, and are you moving at the time? If you aren't moving, transmission slip will always show 100%, because the engine crank shaft is turning, and the transmission output is not. 100% slippage until you start rolling. Similarly, if you look in the data log screen of the iQuad app, you will see %100 slip reported as the max slip every time, assuming you were stopped the last time you cleared the logs.

 

Does that make sense?

 

To add,

As far as I understand, the iQuad tire size settings are only useful/accurate if your truck's cluster speedometer is NOT accurate. For example, if you have oversized tires, and you had a tech with a Chrysler tool correct your tire size to make your speedo accurate, then you need to leave iQuad at the default tire size, or it'll throw the iQuad speedo out of whack. And I assume trans slip.

Or plug your tire size in and get other info too.
