- When the Jeep Wrangler Unlimited Rubicon 392 initially launched, Jeep fans across the globe rejoiced at the fact you could finally get a V8 from the factory. However, some of that steam was quickly deflated when it was revealed that it would not come with the two-wheel-drive option. Thankfully, it didn’t take long for the tuning wizards at Z Automotive to figure out how to trick the MP3022 transfer case into going into 2WD.
On this Inside Line, we’ll show you just how this works along with a few other new features of the Tazer JL Mini.

I got the same color XR, 2021, ordered 6.29.21, finally got it 12.23.22. I’m getting one of those thangs, thanks for explaining it
Oh yeah that green sucks to keep clean!!
Thanks to your recommendation while back now I have tazer JL on my Moab JL and love all the options
Awesome! It really is a great tool to have.
Cool video , thx for all the tips 👍🏼
I like the way you shot this video. The through the door shot and the drone brake turn in particular. Well done. The programming and use of that module gives me tech panic though.
Me to but after seeing all the vids and number users that are out there like Ali, I felt that it would be safe. Also, it helped when my Jeep dlr wanted 200 bucks to reprogram my Gladiator for my new 35's it became an easy decision. It is very easy to use, and you can just easily uninstall (un-pair) it if you need actual warranty service. I bought the light version, but it looks like you can upgrade to the full version by paying for a software update to unlock the full feature list later on if you want. I've been happy so far totally issue free...
Thank you! It's always tough shooting these videos solo. So I try my best to mix up the shots.
@@DK-bs6mu I dont understand why would the dealer charge 200 bucks for such a small detail. I was told that flashing involves reprogramming the gear module not just the speedometer. which I think is not true cause I have not felt any difference in response or transmission shifting whatsoever. but I had to do it since it could be a warrantee issue
Nice in my land cruiser, I had to pull apart my transfer case and modify the center diff to make it 2 wheel drive.
So great of jeep i like
I use the Tazer to have 2wd low in my MT Rubicon (tells Jeep if there is a FAD or not). Nice to have when moving a boat around to neighborhood launch ramp or cruising on slickrock with the manual.
I'm surprised by this. I thought that the transfer case shifter engaged a manual lock for the front and rear driveshafts in 4H-part-time and 4L. Is that not the case? Is the same electronic clutch pack used when you shift into 4H-part-time, and the lever is now an electronic-selector-only?
@@akramer My transfer case is in 4wd sending power to the front wheels, but the FAD never connects the passenger side wheel to the differential. The power to the front just goes to spinning part of the passenger side front axle. If I engage my front locker, only my driver side wheel gets power.
🔥
Great video and very informative. I'd be interested to know if you see better fuel mileage in 2wd vs the standard AWD of the 392?
Thank you. I haven’t noticed any measurable gains from driving it in two-wheel-drive in terms of fuel economy.
I didn't get the extreme recon package because I figured Id replace everything I paid extra for. Now that I want 37 inch tires I kinda wish I had the gears however the 3 73 gears are perfect for the 35s that I've been running for 3 years.
last question Please . Will I be able to go from 4wd to 2wd and from 4wd to 2wd while I am in motion ( say off-roading ) , or do I need to Stop and do it at "Park" each time I need to change between them ?
You do not need to place it in park. Just make sure you are not hitting the accelerator and you can toggle between in drive.
Need help! I have an early wrangler Rubicon 392 picked up 6 15 2021. Now assuming yours is a 22, now is your SGW about the the aluminum support or below, mine is above with only about two inches of clearance around SGW andno way to get to wires to unplug Sgw, all videos I've found so far must be all v6's because plug-in is about 2 minutes. Your help would be appreciated greatly.
I love the all-wheel drive actually. Same thing as my Trailhawk.
It really does work well.
@@DrivingLine yeah it's absolutely insane how fast it cuts on the four-wheel drive. Mine's the same way. It's fractions of a second!
You probably find that when you drive in the rain you can floor it and it's like you're on dry pavement. Once I went from 245 tires to 265 tires on my Jeep I really have a hard time losing traction. It's a blast to drive in the rain.
Quick question, what you average Oil temp running at ? And what’s the highest you’ve seen it get ?
Great video . Thanks . So I can get off road and totally disconnect the ABS without removing the fuse. Also I can go on 2wd while on that mode . That's great 👍
Thanks! And yes, it’s that easy with the Tazer.
Thanks for replying.
Don't you feel that the 392 suspension is a bit too soft for the offroad . My rear wheels keep hopping as I accelerate . I was thinking I had a bad shocks but I m certain it's the soft springs actually when I compare it with the v6 jl lift kit.
It’s a little on the soft side for sure. My main complaint is that the suspension tops out off-road. Wish it had a little bit more travel. It rides really nice on road however.
@@DrivingLine wow that's Exactly my feeling too. I could do more with My v6 JL. I have it lifted 2" which is exactly same height as the 392 but I could tell there is more travel on the v6 than the 392 for some reason. or probably it is a just feeling because of the extra weight of the 392 front end tops out off road.( hood & engine )
That’s a dig feature. Great for rock crawling.
your video's are very helpful thank you for posting them. I have learned a lot. when using tazer and putting it in 2h and the 4 wheel drive light goes out. the light flashes after a few miles. does this hurt anything.
The light flashing is common. ZAutomotive says it doesn’t hurt anything and I haven’t experienced an issue with it. It’s just annoying.
Thanks for your video brother Mansour 👍🏻
does it affect the warranty? Even if unpaired will the dealer’s computer know about it?
Another thing, my driver screen shows a 392 rubicon graphics when turned on which is weird yours doesn’t?
If you need to take it to the dealership, I would just unmarry the device. That should prevent any potential warranty issues. Mine doesn't show the 392 splash screen because it's a '21 model year. The '22 and '23 versions got that update.
👍🏻👍🏻
Great video…..a couple of comments (1) I drive now my 392 in 2WD after watching this video, agree with you no MPG improvement but every 5-10 minutes the 4WD Auto flashes for a couple of seconds, do you have the same issue? (2) I put 37s and although the 470 hp, the 4.56 gears and 8sp make a good job sometimes the Jeep is in D7 and revs up to 3-4k RPMs and doesn’t shift to D8. If you upgraded already to 37s please let me know your feedback on the shifting
I know exactly what you’re talking about with the 4WD auto flashing on the dash. Mine will do that if I swap to 2WD after I started driving it. So, if I am waiting at a light and I decide to click into 2WD, it will randomly flash from time to time. I found, if I let it default to 2WD where it remembers the setting previously or do it right out of the gate after star up, it doesn’t flash. I have not moved up to 37s yet.
Is there any issues with running the 392 in Forced RWD all the time on the road? I have only tried it in my driveway. Great video and your 392 is awesome.
Hey... didn't know you were from Wilmington! So am i!
Yep! Small world!
Those pintlers don’t rub with the Nitto 12.5s? No spacers needed?
No rubbing or issues.
Need help, I have an early wrangler Rubicon 392, delivered 6 15 21.
When checking locations of SGW is yours above or below the aluminum support, mine is about giving about 2 inches around sgw making it totally impossible to unplug. All videos I've seen must be all v6's. With that being said and your sgw is above support , how long did it take you to plug in. Well appreciated thanks.
Mine is above on both my gladiator and 392. Basically same location. Not sure why yours would be any different.
With having the extreme recon package, will the 37 fit without any rubbing and any lifting to the jeep?
On the road, they will be fine. Off-road I believe they will rub. I'm going to install a set and find out soon!
@@DrivingLine Keep us posted ,please !
Hello again,
Do I need to Marry the device to the JL if I just want to use the " live Menu " or "Non-Menu Live Functions" features ?? in other words can I plugin and directly use menu items such as 4wd/2wd , line lock and disable TC & ABS. etc ? and then plug-out at the time when i need to take the car to the dealer?
so far I understood that marrying is involved only when I need to change vehicle settings.
Thanks for your time 🙂
I’ve always married the device. I think you have to marry it for all of the features to work. If you’re going to take it to the dealer, all you’ll need to do is unmarry it from the vehicle.
@@DrivingLine Thanks my friend. I will do that. I enjoyed your videos . 😁🏆
Thank you!
@@DrivingLine ok new update . I was able to use the live functions without marrying the device . That was a bit of a risk but it works. So here is something new for everyone . Be safe 🙏
Hi there, can you increase the speed limiter a bit? My throttle gets killed and the RPM is still at 2.5 or so, there’s still a lot of room
The Tazer won’t change the speed limiter. I haven’t looked into how to do that.
When in rwd mode did you notice any differences in your fuel mileage?
It’s maybe 1/2 mpg better.
It's not about the weight of the tire . You can have a 37 at the same weight as the 35 and it would still kill your power. The change in tire size changes the effective gear ratio.
Is there a difference with the mpg when in 2wd?
I haven’t really noticed a difference.
@@DrivingLine Thanks for the response
So you can turn it on and off on the fly just by pushing that button?? You don't have to constantly go into the settings? Thanks.
Correct. All you need to do is map it to the steering wheel and you can easily swap from 2WD back to 4WD Auto. It will also remember the last setting you input. So, if you clicked 2WD and left it on, the next time you get in the Jeep, it will still be in 2WD.
@@DrivingLine thanks 👍, I'm getting ready to install the Axle disconnect motor onto my 392 and am going to put a switch in the dash, I'm doing this so the driveshaft doesn't turn while in 2 wheel drive. Also will be installing RCV front axle shafts when I do. Thanks for the response
Update, installed the front axle disconnect motor, put a small switch on driver's side towards bottom of center console, works great, driveshaft does NOT turn anymore, I've got 5" or more of lift on my 392 extreme recon, also noticed right off better gas mileage and the vehicle actually goes into 4 cylinder mode while driving, which is great, 8th gear 40" tires 1500 rpm at 80 mph. Of course I do know how to correctly measure tire height, and it's definitely not like people do on TH-cam 😅😅😅.
It’s interesting that it has a speed limiter yet the g wagon just keeps going. Both are high powered boxes and both are all wheel drive.
El limitado de velocidad es por los neumáticos of road, el código de velocidad de ellos no es elevado y podrían reventar a alta velocidad, si pones unas llantas y neumaticos on road como los de la g waguen, puedes quitar el tope de velocidad y ver hasta donde llega, pero la limitación de jeep es para evitar problemas en carretera a alta velocidad de los neumáticos off road
Any MPG improvements?
Not really. As I get more miles on the Jeep, the MPG has improved from when I first got it however. In the 4Auto mode I'm now averaging 15.
@@DrivingLine wow that’s the same as my Mojave with 37s and a 2” spacer lift.
I'll only use NITTO on my JK!!
Won't this void the warranty 😢, worried
I might remove while taking to service , but won't they come to know .....
Awesome video!! Thanks for sharing. Based on your experience so far with the 35s and the stock lift on the 392 XR package, if you switched to 37s, do you think you’ll need to adjust the lift and/or wheel spacing to avoid rubbing?
There is another video on here of a guy going to 37s even without the XR package. Without doing any adjustments it would rub while full right or left. It would also rub when fully articulated for the articulation I’m curious if the extra 1.5 inch from the XR package would help prevent rubbing. As for when it’s full left or right it barely contacted but would probably still need an offset or spacer.
Thank you! I think 37's will rub. How much will likely depend on the brand and the wheel's backspacing. I'm going to try it out. My gut is the front will be fine, but the plastic part inside the rear inner fender that hangs low will need to be removed.
@@DrivingLine Not trying to assume your budget but if you had the opportunity to show different wheels with different offsets. Then show clearances you would be the first as I haven’t found any others that have. Most people have said if you drive mostly paved roads you would be fine. I rather see it shown to me not just take someone’s word on it lol. Think that would interest a lot of others who own or are looking at buying a 392.
I actually have access to two sets of 37's both on wheels. If I can swing it timewise, I will test both.
@@DrivingLine awesome man look forward to it. In the mean time I’ll be sure to subscribe and follow for notifications.
Hemi 392 Jeep Wrangler
How much highway & city - mpg do you get in 4x4 vs 2 wheel drive?
I haven’t noticed a difference. This thing averages 15 mpg on the highway and 13 in the city. It doesn’t matter if it’s in 2WD or 4WD Auto. I should note that it’s now on 37s and that’s my current fuel economy with them.
@@DrivingLine
good to know.
I got my 392 with the 33s and 3.73 gear ratio. I just installed 35s and was wondering would I need to re-gear to 4.56?
It’s going to feel more powerful with the 4.56 ratio, but I don’t think you need to regear for that small of a change in tire size. If you move up to something like a 37, I would.
@@DrivingLine I have no plans for 37s I like 35s and when I saw Jeep re-gearing to 4.56 on 35s I thought maybe I would need to re-gear
I ran 35s and 4.56 gears for about a year. The power in town was great. But, it revved pretty high on the highway, which actually hurt and feel economy a good bit. With 4.56 gears and 37s (what I am on now) it seems to be a better balance. I don’t think I would bother with regear unless you just feel like you want that extra snap of power.
@@DrivingLinegot it 👍
3.73s are perfect for 35s. You can drive 80mph at 2000 rpms. No problem staying in 8th gear on the highway and you still have loads of power. Many people don't even regear with 37s.
My firmware version is 11.3.4 and its the latest so how did you get firmware version is 11.3.5
I had a question about something with one of the earlier versions and reached out to them directly. They told me there was a newer version they were working on and emailed me the file. I thought it would be up by now.
It's useful to bury the rear tyres on sand to anchor yourself and winch out someone.
That it is! Definitely have had to do that before.
why don't you have a link for the tazer?
www.northridge4x4.com/part/programmers-tuners/jl-tazer-mini-z-automotive-prgmr?gclid=EAIaIQobChMIt5SS5ZC09gIVR2xvBB0XgwS8EAAYAiAAEgKhQvD_BwE that’s where I purchased mine. You might be able to find one cheaper somewhere else. We don’t have affiliation links as this is not a sponsored part.
Will this delete the top speed limiter
No, but the same company sells a separate device for that.
Can you delete MDS with the Tazer ?
Not that I am aware of. I haven’t seen any updates that would allow that with the module.
Can I increase the speed limiter?
I don’t think so.
What’s your MPG in 2wd?
I average around 13.
How can this jeep get any better ? Only thing I can think of is cast iron steering knuckles.
All 392’s actually come with cast-iron steering knuckles and the iron gearbox!
@@DrivingLine Well that’s awesome!! I thought only the Mojave JT had cast steering knuckles. Thanks!
AEV wheels are 17x8.5
You are correct. I misspoke.
392 is full time 4WD ? I have a 2016 JKU “75th Anniversary”, which I use 95% of the time in 2WD.
Correct. It doesn’t have the 2wd selection from the factory.
@@DrivingLine man, bit of a bummer, rather have mechanical than digital selection, surprised they still have 4WD hi/lo mechanical, I had a ‘92 Mazda Navajo (2 Door Ford Explorer ), that had that push button 4WD, hated it, the days where you had to back up to unlock the hubs. Gotta say, my 1997 Isuzu Trooper had the best 4WD system in all the SUVs I drove (91 TJ, 92 Explorer, 82 Grand Wagoneer, 2007 Commander (QuadraTec), 2016 CX5 (AWD), 2016 JKU), only vehicle better was my friend’s 2003 4Runner. Never got stuck, I had it in 3ft freshly fallen snow, 1ft deep mud, always got me out.
No RWD 392 no sale ;)
so why jeep team Decides 4wd only
the customer need 2WD
ford do that in bronco
At $6.00 a gallon, ease up on that pedal. ;)
No kidding!
It has too much garbage that i would never use if a had one of those I'd just use 2wd and the 4x4 low or hi and thats it
But will it do a doughnut?
Oh, yes. It sure will!
Had my 392 for 3 months. LOVE IT
@@DrivingLine will it do a broader in 4 wheel? I think it would be easy in 2 wheel:
this is something a millennial would do.
Yep! 🙂
You guys miss the entire concept of Jeep. It’s just embarrassing.
🤷🏻♂️ This is a video about making the 392 able to have 2WD. We have plenty of wheeling videos on our site where we put a multitude of Jeeps to the test.
@@DrivingLine you still don’t get it !!! Jeeps are not high horsepower drag strip rocket ships. They are compact capable low horsepower off road vehicles. They crawl slowly over rocks and have systems that for the most part can be repaired by a non-mechanic people out on the trail !
@@Soothsayer-rs5nb
never argue with fool's
@@Soothsayer-rs5nb ok boomer. First it’s his jeep. Second it’s his jeep. And there are plenty of rock crawler jeeps built with 400+ horsepower cause why not
Lol
