I use this one.

Comes with a nice little box to store it in as well.

JSCAN and AlfaOBD both highly recommend.

JSCAN and AlfaOBD both highly recommend.

That's the one I have, because it was the ONLY one recommended by both JSCAN and AlfaOBD for the JL/JT Jeeps.

Exactly, and I have both.

Im using this guy, as I had it left over from my Z06, works perfectly

The differences between, say just for example, the MX+ like shown and some others is SPEED.
I tend to get deeper into things - I'm snoopy and "research" and experiment. That's me, always have been that way my whole career as a mechanic, or dabbling in electric.
I was actually told by one of the softwares that it couldn't access a module I was trying to get to with the adapter I had and needed x, y or z adapter. I can't recall if it was JCSAN or AlfaOBD telling me that now, however.
For most people, the top of the line won't matter.
I've found I always regret not getting the better version of something.

Makes sense to buy once, it may be 4 or 5x more than the Veepeak that I posted but if you're planning to do more with it and it's recommended, then not a bad option at all. For the basic stuff I've gone in to do, the cheaper Veepeak one does the trick, and has good reviews to back it up.

I've got an HPTuner already at $400 that I can dig in deeper with so I didn't really want to spent a lot on a quicker bluetooth solution to set a couple things like tire size.

Good to have options.

Either way, I can't really say I support the Tazer fully. But that's kind of another topic.

Thanks, I am only wanting to adjust tire pressure

Not really, when it comes down to making configuration changes.
The only advantage that the MX+ has on most other interfaces is that it is capable of automatically switching bus pins internally, so it can connect to, and diagnose, all of the modules on the vehicle without the “blue adapter”.
All of the interfaces use pins 6&14 on the OBD port (which is canbus c). Some of the modules on the vehicle are on the IHS bus, which would be pins 3&11. Most devices can’t connect to those pins automatically, so they need an adapter that move the wires on the OBD port from positions 3&11 over to 6&14.

Since the BCM is connected to on the can C bus, and that’s where all the configuration changes are made, the cheaper interfaces will work just fine. Now, if you’re using a $20 BAFX in a long session, like manually configuring the whole BCM on the bench, then you might get an idle status from the interface once in a while.
But, with the cheaper ones, they can’t connect to IHS bus modules. So you couldn’t diagnose issues with modules such as the radio, amp, door modules, CVPM, hvac, integrated center stack, heated seats, and blind spot monitoring.

On another note, I’ve found an alternative to recommend for the MX+, since its price has been running away for the last couple of years. I’ve been use a vLinker MC+ for my bench setup for the last few months, and I can’t tell any difference performance-wise between the two. It’s pretty much an MX+ clone, but only $60.

One of the apps talked of speed as well - it wasn't able to write quickly enough. It's in their documentation.
Then I ran into "cannot access......................... " and it said to use the MX+ to get there.
So I got an error with the first adapter I bought.

Here is one snippet from AlfaOBD -
As the OBDLink interfaces have high communication speed they are especially recommended for the Body computer configuration adjustment and odometer correction on Chrysler/Dodge/Ram/Jeep vehicles.

I did run into issues trying to write changes to my 2020 with the first OBD adapter I bought - had to try twice. Was told speed was the issue.

The adapters are mentioned as possibly being needed for some of the interfaces. The MX+ has connections to anything needed for Jeep/RAM, etc.

In the end, if it works, use it. I got tired of having to retry multiple times or lack of access to certain things with AlfaOBD. They do things differently than JSCAN. And I've noticed JSCAN can be painfully slow when trying to do configuration dumps - when gathering all info. Takes forever. AlfaOBD is there quickly.
But it won't work to access what I want with the 2022 model years.

Most adapters will do that without trouble.

Did you have to buy the cables also or did it work by just plugging i in?

You have to buy the bypass cable no matter which programmer you use
