Z Automotive Tazer JL JT Lite Programmer | Fits 2020-2024 Jeep Wrangler JL and 2018-2024 Gladiator JT | Change Tire Size, Gear Ratio, TPMS and More!

Takes a minute to pair and set up but it does what claims to as well as a couple non menu items like the last known setting on the auto start. Does not completely disable it but start up puts it in its last known state. Speedo is dialed in finally with my 35's. And the tpms settings are really nice.

Easy install easy to control

Worked exactly as advertised. I purchased it so I could change my tire size and disable tpms. Very pleased and would buy again.

Had to update before it will work

Works great, installation directions are challenging, also not sure why the box comes marked with z locker which is a different product for the tru lock lockers found in Rubicons and the rear axle of the Willy’s., I was apprehensive to open the box, I even returned the first unit unopened because I thought they shipped the wrong product ugh. Be sure to update the firmware first on a computer. had no trouble finding the Jeep harness plugs to relocate to the tazer, had to remove panel under column to access the module, then pry the fabric panel surrounding the column base to get at the connectors. I’m a little mobility challanged and had a tough time getting in a physical position to make the necessary changes under the dash. I recommend getting the optional extension cable. programming commands are left arrow followed by cruise function, I had to watch a you tube video to figure out the arrow symbol on the instructions was the left arrow button on the left side of the steering wheel the instructions use a combination of symbols and words. you need to hold the left arrow on the left side of the wheel while you use the cruise buttons on the right side of the wheel to marry the tazer Guess I’m not the sharpest these days 🤦🏼. I bought this primarily for the Start stop last state and TPMS features, and they work flawlessly. My jeep is a 2025 Willys unlimited, sadly the unconnect 5 infotainment system is not compatible yet. So I couldn’t use some of the other cool features older JL Jeeps can access, will check back later to see if future updates will offer more functionality. I bought the lite version, plan to upgrade it to a mini if the other features are sorted out.

I have completely removed and unmarried the Tazer Lite after a year of use and will never use it again. I bought the unit to ensure an accurate speedometer reading after changing the size of my tires. 4 months in, battery showed signs of dying… malfunctioning blind spot monitoring, weak start. I realized I had just replaced battery not long ago. Did some research and found Tazer may be slowly draining battery, so I took out the Tazer as the speedometer still will work. First oil change… forgot to unmarry. Mechanic can’t reset oil life… I figure I can live with that and will unmarry next time. Meanwhile, as time goes by, the Jeep starts having radio issues and other electronic issues. Next oil change time comes. I figure out the unit needs to be plugged in to unmarry. It is a pain in the ass to install. Get it back in, unmarry, and now radio works fine. I have taken it out and will never put it back in. This is the biggest waste of money and biggest pain in the ass on so many levels. Do not buy a Tazer!!!

Great investment for programing just for what I needed. Easy to use and was able to change my upgraded tire size with no issues

Works like a charm. I corrected my tire size, turned off the auto start stop, and dazzled my friend with a light show.

Good quality , It serves the purpose perfectly

Excellent Product. Have not had a single issue. Originally bought it to shut off auto start stop but have used it for many other settings. Changed tire size after upgrading and the winch mode is super handy when it is -40. Also the tire fill option is cool and works great. Many more options I havent used yet but excellent so far

This purchase was extremely frustrating and misleading. At the time of purchase, my Amazon interface was Arabic only, and the Arabic product listing implied or labeled the device as “Tazer Mini”, which is inaccurate. Based on that listing, I reasonably believed I was buying the Mini version, not the Tazer Lite, which has significantly fewer features. After purchase, I was informed by the manufacturer that the device could be upgraded, so I purchased an upgrade code. Only later did it become clear that my unit is a European model that does not support Amber DRL color at all, regardless of upgrades. This critical regional limitation was never clearly disclosed by the seller or in the Arabic product description. Additionally, even after purchasing the upgrade, not all features or functionality are available, making the upgrade misleading in practical terms. Due to misrepresentation in the Arabic listing, lack of transparency regarding regional limitations, and poor handling by manufacturer support, I do not recommend this product and strongly advise against buying it from this seller. There are better and more transparent alternatives available.

Great for calibrating and shutting off the start/stop
