If you want to upgrade your Jeep's look and feel by installing larger tires on it, this is the easiest way to get your speedometer and shift points recalibrated without having to go to the dealer.
Using the Z-Automotive TaZer JL, you can easily calibrate your speedometer for larger tires.
Step-by-step process:
1. Make sure the TaZer JL is updated with the latest firmware
2. Easily install the "plug and play" TaZer JL into the Jeep's Security Gateway Plugs
3. Marry the TaZer JL to your vehicle using the TaZer menu (vehicle on RUN, but ignition not on)
4. Fill the Tires to the recommended PSI found on the Tire
5. Measure your tire using a tape measure or yard stick for best results
6. Input that measurement into your TaZer's Tire Size section, which is found under the perf? (performance) menu
7. Do a full reboot and two sleep cycles to solidify that setting
8. Go on a 20 minute drive (preferably highway) to ensure that the TPMS and the shift points fully recalibrate
9. Subscribe
Note for Tire sizing and calibration of the speedometer:
If it’s reading lower than actual speed, raise the tire size setting.
If it’s reading higher than lower the tire size.
If you are performing any vehicle setting changes (vehicle in RUN but ignition not on) using the TaZer Programmer, such as changing the Tire Size or Gear Ratios, it is critical to perform the full reboot and two sleep cycles. Missing this step may cause settings to not save, or you
may find that the dash doesn’t shut down, which can result in a dead battery.
If you are performing these changes with your Jeep Wrangler or Jeep Gladiator doors removed, you will still be able to perform the reboot and sleep cycles, although the Jeep will take longer to fully go to sleep.

I just bought a 2021 Jeep with the mini on it and I had no clue what it was. Thank you for this and all the other videos!
Plenty of more to come! Let us know if there’s anything specific you’d like us to cover
Tire size, your manufacturer actually lists it accurately on their website. My Falken Wildpeak 35's are actually 34.5.
Do you have a video showing the full processes for a manual transmission JT?
Sorry, we do not have a manual transmission Jeep JT as part of the Z Automotive fleet. Here is the process to calibrate for that vehicle, www.zautomotive.com/zpu/instructions/jlm6relearn.pdf
Can you change mutiple items before performing the full reboot, sleep cycles and test drive? For example can i change tire size, gear ratio, and tpms and then do the reboot, sleeps, and test drive? Or do I have to change tire size, perform reboot, sleeps, and test drive and then repeat for the other changes i need to make?
Yes do the one full reboot, sleep cycles, and drive cycle when you’re done adjusting all your settings
@@zautomotive awesome! That is definitely easier and less time consuming than after every change. I appreciate the reply.
I recalibrate the adas system. I use the security gateway to gain access when changing the windshield. When disconnecting this will it reset my tire size?
You can disconnect the TaZer after recalibration of the tires and it will hold
after setting for tire size do I remove the tazer JL lite ?
You can, yes. If you’d like to utilize the live feature settings though, it would need to remain plugged in
Can you kill the speed limiter on the wrangler 392?
No
I have factory 4.88 gears. Do I need to change that in the Tazer Lite? Or will the factory settings overrule. I just upgraded my tire size. Not sure if I have to let the tazer know the gear size though
If the dealer already flashed it for the new gears then you don’t have to set it in the Tazer menu
I have tires and rims coming for my 2020 JL. These are the largest tires that can be used without a lift. I don't have a nav screen like shown here. Is the process still the same?
This is the EVIC screen above the steering wheel not the navigation/radio
Will the TaZer mini ever see an app where we can make changes from there as opposed to making changes on the dash of the vehicle?
maybe
@@zautomotive I think this would be a game changer and hope to see it in the near future.
@@HANK_SCORPI0 👍🏼
I dream of that day... along with a working sway bar disconnect total control and total blackout... I'm a simple man.
@@mcoffroadinaz4075 we have swaybar disconnet - "disconnect sway bar in 2WD up to 30mph or at any speed if mapped to a button"
Once I recalibrate the speedometer can i take it off or i have to leave it on
Can remove it
Will this calibrate your speed once you do the tire size??! We just purchased and done the steps but my speed is still off
These are all the steps to calibrate the speedometer. If after the drive cycle you see no change, please email our customer support for assistance- support@zautotech.com
How do you do this with the manual there is apparently more steps and the instructions are not really making sense
email support@zautotech.com
does this work on a gladiator sport model?
Yes
How does one do a sleep cycle if the doors are removed?
Opening and closing the door makes it go to sleep faster, so if the doors are removed you would just have to wait longer. Wait until the screen and dash is fully off
@@zautomotive Thank you!
Will this calibration help with MPG?
It’s the tire size that determines the MPG. Larger tire size, worse MPG
Why does my Tazer Mini always blink Red ?
To show its sending a signal
I installed the tazer today and set the tire size. do I unmarry it and the settings stay in the Jeep ? I have 2 more services at the dealer and them I'll probably leave it in.
The settings will revert back to the default settings once unmarried, so you'll have to reset the tire size after getting back from the dealer
@@zautomotive Ok thanks
How did you remove the front kick panel? I can't get to the connectors to remove them from the security model
there's a little tab that needs to be pressed in to release the connectors
@@zautomotive I see the tab, but I can't press the tab and pull the connector out at the same time. I probably need to remove the kick panel, like shown in this video, to get to the connectors easier and have more room. My question is how did you remove the kick panel? In the video you showed how you put the panel back, but not how it was removed.
@@Mark-zq2iw I see. The kick panel has little tabs on the back, essentially just takes even brute force to pull it off or can pry it off tab by tab with a plastic pry bar. I can send you a picture of what the back of the kick panel looks like if you send me an email at nsilvia@zautomotive.com
If I leave the Tazer installed when I bring the Jeep into the Dealer for just oil change and tire rotation will they void warranty?

I would remove it. As it might vanish mysteriously. No need to give someone an opportunity to steal it.
wth do the tpms sensors have to do with calibrating the speedometer?
If your tires are incredibly low on air, they won’t be the same height as a tire that is correctly filled up with air. Common sense
@@zautomotive I run my tires at 36psi on the road…don’t care about the speedometer off road
@@GenX_Dave that part of the video was a reminder to have them at the road tire pressure… again, if someone had their tires very low and then measures the height, it would not be the same height as a tire with proper road tire pressure
@@zautomotive should I input the true measurement? or what’s on my sidewall?
My brother has a 2020 Jeep Rubicon Gladiator with 40s. Will this work on it?
If not, do you have any recommendations for fixing this issue with his Jeep. Thank you for your time.
Why did it blink serv 4wd??
Timestamp??

@@quepasatim sometimes lights flash when marrying
Love my tazer. Hate to be that guy, but wouldn't we want to measure from ground to center hub and double the result? The bottom half of the tire is compressed under load while the top is not. The distance from hub center determines number of revolutions at a given absolute speed. Not taking this into account on the upper half of the tire ignores the load compression and over states tire size. Bottom half radius is the constant...Top half radius never happens. Also, for me, once I got a decent measurement I used a GPS enabled speedo app on my phone to check the tire size change in motion. After a couple adjustments, I got the onboard speedo and the app to agree exactly!
They wouldn’t have to do so many videos if they made it user friendly
Feel free to buy a different product if it’s too complex for you 🤷🏻♂️
also, this video leaves out waiting 60 seconds after the dash goes dark…according to the directions online, you are supposed to wait 60 seconds after the dash goes dark. Why does he not do that. If you guys are going to make support material for your customer base, at least make sure the information is consistent and accurate
Yes, the manual says 60 seconds after the screen goes dark and that is a good habit to get into to solidify settings. Although generally once the screen goes dark, the vehicle is in a sleep state. If you’re unsatisfied with the video material, feel free to just stick with the written manual
@@zautomotive I’m unsatisfied with everything…including your tone
@@GenX_Dave just mirroring yours 😏
The latest update was 1/19/2023. Is that right? No updates in 9+ months?
Is there a problem with the current version?
@@zautomotive nope but got used to updates every so often. So I thought I was having issues getting updates. Sounds like that was it.
@@Haro75410 no updates have not stopped if that’s what you’re implying. If you keep up with our content, you may notice that we continue to put out updates for the Tazer and Tazer DT, with the goal of putting out an available version of Pin Lock and all the new features involved with it. After we iron out some bugs and have a stable version we will move on to the Tazer JL
