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!

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.

Very happy with this unit. I did everything that I needed it to do.

Great product! It’s able to do more things than I thought. I just needed the speedometer corrected. We did that plus turned off the tire inflation warning.

Does what it claims, however the directions are very complicated. Simplifying the directions for the average person would be appreciated.

Performed as described. Allowed me to change tire size and stopped the annoying seatbelt ding. Best part is it remembers the auto off setting so I don’t have to keep turning it off.

Often my Jeep wouldn’t start on first try. As soon as I removed this, the problem was gone. I had used it to keep auto-start-stop off. It doesn’t always keep it off. I like how you can upgrade the features at a later date but at an extra cost.

Bought this after upgrading to bigger tires on my 2021 Jeep Wrangler, it was an easy install and easy to use after watching a few YT videos.

I love this thing and needed it to adjust my tire size. It has a lot of great features that go beyond the primary purpose for me, so you get a lot for your money on this one. I like that you can get firmware updates from Z Automotive which will include additional features so you can buy once and keep using this for a long time.Ease of installation is vehicle dependent. That said on my Jeep it was difficult for me to reach under the dash to disconnect the cables and get this in place...luckily I also bought the extension cable so in the future it will be so much easier. I highly suggest that extension if you are buying one of these for your Jeep.Great product, works flawless, provides more than you realize when you bought it and I highly recommend it for anyone offroading.
