Living with the JB4

Yup. JB4 was reading well over 33lbs of boost. I almost wonder if the data isn't accurate. I'm only just over 5K miles in on the odometer, but about 3,500mi with the JB4 which I know isn't a lot. This pic is the only problem I've had after running the dog $#!+ out of it on map 4 with an e30 equivalent (93+E85). I noticed it when I was trying to park, because obviously it ran bad. I thought I broke it. NOPE. Just popped this sucker back on and gtg. I probably ran 1500 HARD miles on this map. I think it would have broke if it was going to. Since then I've backed off to 93 and map 2 just because going out of my way for e85 isn't always convenient.
I can’t exactly tell from the pic, but I’ve seen another member experienced issues with a hose popping off. From what I understand, Ram updated that connector late in 2025 MY, so might be something you can get replaced under warranty.
 
My friend was curious if anyone had tried the Beta firmware on the JB4? Something about more low end torque and “anti lag”

I am.. it is a game changer! MUCH more "Drivable".
 
There's a beta? I never check haha guess i will.
 
Did you adjust anything or just went with the maps that were downloaded?
Just went into that map, i am going to try the "antilag" portion this week

Interested in hearing the results! I have both the JB4 and Cat6, Cat6 is installed right now and feels better for daily driving. i'll swap back over to the JB4 if it is more refined with the latest update.
 
In the JB4 app they have stable, beta, and alpha. You can download and flash whichever but I’ve heard to stick with stable or beta.
Thanks. I’ll check out the app. Never seen those options before.
 
Between the two BT options… which did you guys go with? The separate dongle or the internal BT chip using the JB4Pro app? I’m curious if there is any difference in functionality between the hardware or apps.

Nick recommended JB4Pro to my friend.

What if your friend already had the 3rd party BT Dongle? Would Nick still recommend buying the JB4Pro module? 🤔

I think you’d be fine since you already have the adapter. @Nick797 could probably help explain what’s different between the two

Pro has the wireless chip built in...also uses a free version of the app, with this chip. The other uses a paid version of the app that visually looks nicer I guess. I will take the built in chip and free app to change the map.
 
Hey Guys!

So the JB4 PRO is their new add on, utilizing a new free app that they developed vs using a third party app.

I have seen BMS mention that they would send users who previously purchased what at this point could be considered the older version, a JB4PRO.

What I am thinking is that the more expensive option currently will be phased out over time.

So, if my buddy has the older version and has never opened or installed it yet, you think BMS might send him the JB4PRO?

P.S. My friend bought it from you

Terry (The owner of BMS) is active on the Facebook groups and he mentioned that, which i think is a really nice gesture and to keep people supporting the product.
 
To summarize, us with the JB4 using the mobile app may need this new adapter to work with the Pro app? Is that what I'm reading?

I don't think they are going to just get rid of it right away, but I was just thinking outloud that it wouldn't make sense to continue the two forever being they do the same thing. It looks like some of the older cars that run with JB4.

Little more info when it was announced
