The real truth... JL Tazer Mini & Forced RWD.

[JeepJibboom]

Here is what I got back from them a couple days ago;



We just purchased a 2024 model wrangler 392, and the Tazer firmware is still in development.

Most of the features are working with the 11.4.4 firmware except the ones related to the Uconnect 5 radio. Turn Cam, Nav in Motion and the camera features are still in development.

I just don't have an eta at this point for full compatibility, we will make announcements on our social media channels and if you follow them, you will get the notification.

I got the same reply word for word. Copy pasta.

LOL... good to know ..... figures though. I am in zero rush for a Tazer. I want one but will wait to see how it plays out for a while after they bring one for the 2024 392 to market.

Too old and cheap for burnouts. Rubber is expensive.

Tazer gives me piece of mind to activate 2H when my transfer case inevitably grenades once again. I only use 2H on the Highway. I don’t lIke spinning tires from a dig.

I‘m guessing in hindsight, 2H and a Dana 60 rear would have been cheaper than all these broken transfer cases. YMMV.

I'm sorry but are you thinking if your transfer case critically breaks apart you will be able to select 2H and drive on home?

You mean breaks apart again? After having my 392 sit at the dealer for 43 days, I wanted another option. Will keep everyone posted.

Yes, unfortunately I mean breaks apart again. Not trying to start anything up but I cant see how it can be drivable in 2H if the transfer case has broken apart. I must be misunderstanding you. Sorry you had to wait for parts. Jeep has done that to way too many people

What happened?

What happened?

This. If you are waiting on the TCase that's BS. Mine went the day I was leaving on vacation just before Thanksgiving. My neighbor works at the dealer so she drove it in for me. Therefore I wasn't able to nag them AND of course there was a holiday closure. Even with all that I think it was 2 1/2" weeks? I am in California and this was a large dealership; that's the only thing I can think of. Do bigger dealers get priority on parts maybe?

Someone on a prior email mentioned the Tazer helped eliminate the Service4WD codes but I found that all I had to do was turn the Jeep off for a few minutes and it went away. (And re-engaged.) So I am not sure that's a Tazer thing.....? Mine never got "stuck" in 4WD permanently but I knew exactly what the issue was so I took it in. There was zero argument.

No offense taken. TC shit the bed at 3K miles a few days after Fins & Things and Hell’s Revenge (easy trails / didn’t do any of the crazy optional obstacles).

I won’t name the dealer but had a really bad experience with their service advisor. Had to use them as my preferred dealer didn’t have a transmission tech. Felt like it was the GM‘s autistic kid and everyone else was covering for him.

No loaner. Horrible comms. He once claimed they had no record of my vehicle being there. I threatened to call the cops since it sounded stolen and finally got to talk to someone competent. Claimed my first replacement TC was lost in shipment. Waited 43 days to get a second TC shipped and installed.

I‘m fine being a tazer Guinea pig if it happens again. If it does, hoping I can still force 2H and not have my rig sitting with the dealer forever.

I only use 2H on dry highway and enjoy the convenience of having it programmed to my cruise control button. No hooning or burnouts. TC was low when I checked and filled it at roughly 2K miles.

I love my 392. Considering what we paid, we should have received a Dana 60 rear, 4xe TC, and 25 bolt rash rings for the XR wheels.

In force rwd, the front drive shaft still spins correct?

Yes

just for the other people here
i did have a TC fail over the course of 30-40k on my 392 wrangler. meaning from first yellow light and the other symptoms in threads here
and then did the actuator that lasted another week or so,
and then had to do the whole TC under warranty
They gave it back to me while waiting on the new TC and i drove it in 4WD auto which was functionally RWD only until the new TC came in
obviously not a critical failure but as clearly demonstrated whatever is happening with tc failures is not always a critical failure

I agree but when I hear grenaded.....I think of lots of xfer case pieces all over the place.

Of course I meant to type transfer case...just a typo.

Scott Blum and Jamie Standring both FCA employees, and Joe Zizzadoro owner of Tazer, replied to my post on Jeep Wrangler Rubicon 392 Nation... Real Truth About Tazer Forced RWD.


Scott Blum: the Tazer does what you described at a high level yes. The intricate details Joe would have to answer.
Remember every 4xe out there, every international JL/JT ever made and tens of thousands of 3.6/2.0 JL/JTs have the same full time case in them. And they all have a 2H mode. The t-case is made to run that way.
That answers questions 1-3...


Jamie Standring: If you recall the reason we did not offer 2WD was rear differential life. 2WD puts additional torque through the rear differential & gear/bearing life is proportional to time at torque. As a rule of thumb a 10% increase in torque will half life.


Joe Zizzadoro: The DTCM controls the transfer case mode. The 4XE which has the same case, has 2WD mode.
In that case they limit power from the electric motor to keep torque levels down. They don't do that in the 392 so they don't allow 2WD.
The Tazer simply tells the DTCM to override and go into 2WD mode. No real magic. But the torque is there. Daily driving is no problem. Burnouts, donuts, etc is always a risk as you're stressing the system - so might you break something? You might. Heck of a lot of fun till you do, though.




*Someone asked... for those of us who have upgraded (?) to like UD60's and locking manual hubs.. should I run in Forced 2WD with Tazer as I'm not putting power to the wheels as I drive with front hubs unlocked?

Scott Blum: ...that's you call. I run Curries in mine with ujoints and still run in 4A. I can occasionally tell in a dry parking lot with tight turn as I feel the slightest crow hop. So what that says is under normal usage very little power is being sent to front tires.
Now if it slips it will dump more power to front. Like wet, snow or just having fun with your 392.
If u leave hubs unlocked and still in 4A it's going to still be seeing the minimal power up there but it won't transfer to tires. I doubt that would hurt anything. But if u really bust the rears loose and it sends a lot of power to front u r going to lose forward power by whatever it cuts from rear and sends to front. It will only send so much up there. Not sure how much it would flake out.
If I was running with hubs, I'd either leave them locked and run 4A, or unlocked I'd run in Forced2WD. That's just me.

Reminds me of a thread about running 75W140 Full Synthetic in the differentials....

 

[Smess]

my 21 recon was heavily modded with Tazer and pedal commander. one day I lost the stereo display and we waited for the parts. it was actually an amplifier issue. after we fixed that then the rear cam went out, we had to end up replacing the entire harness under the console. when they reprogrammed the jeep it would start and screen would say 1941 rubicon but not 392. tech is a friend and told me only mopar can come out with their super compute and fix this but a recon with 6k miles hmmm and look at all the money spent. tech said you have a 50/50 chance they dig deep in computer and see the security gateway was disconnected as that's what the Tazer does but they also know about the Tazer and I might lose my warranty. I said hell no not for it to say 392.

I use the Tazer to do some fun stuff but I dont force 2wd anymore as that is not the strongest 4wd system in the jeep line up and force 2wd and pedal commander juiced up and you can trash a case real quick.

I do the pedal commander and some Tazer features but two techs have told me I am playing with fire jeep knows what we do and if I want a 90k jeep with no warranty keep driving it like a sports car.

no thanks I will pass.

I put it on my 24' 392 the only thing I noticed is when I put it in forced RWD which is the main option everyone wants the light on the dash will flicker. but I was told by Taser that its normal and is in forced RWD. Now I just put in UD 60s and have not tested it out yet with the new DIFF. so fingers crossed I will let everyone know the result. Also I read a few people that have used the HP tuner with Flashing the PCM then unplugging the HP tuner and plugging the Taser back in and from that persons review it also worked. just an FYI for those DYNO folks.
