Jb4

Sigh... this frustrates me.

I'm not shooting daggers at you; I appreciate you passing on what you were told. Unfortunately I think Burger is either misleading intentionally or out of ignorance. Neither are good.

In their antilag feature setup they have you adjust the "default wastegate position" in their app. Last time I checked, the wastegate was attached to the turbo, not the pedal. How are they controlling the pedal?

Now, if they really are able to manipulate throttle mapping at the pedal somehow, great. I'm all for that. But what their answer fails to mention in "improving turbo response" is that you're modifying the wategate to behave in a manner which keeps the turbo spooling when it normally wouldn't.

There are two strategies a vendor can use when releasing a modification that could be seriously impactful to the continued health of an expensive part like a turbo, which we are blessed (or cursed) with two of.

1 - candid disclosure about how it works, what it does and what the risks may be.
2 - a non-answer answer devoid of any appreciable detail.

Which vendor would you rather purchase from?

This gives me all the reason I need to avoid a JB4 right now. That's coming from a former JB4 user on 2 previous vehicles. This smells deceitful to me and I don't like it at all.

I hope I'm wrong and someone gains more clarity on the matter.

I edited my previous post to include the question I asked them. Hope this helps give some context.

I’m personally still waiting on direct connection to release the unicorn tuner. However I would be curious to hear from someone who gets JB4s new tuner as to whether it is more responsive.

It’s not new. It’s simply a user adjustment if one so chooses to experiment with it. If you decide on the Cat6, then you have the direct connect with a different brand tag.

They certainly advertise as if it’s a new feature they have added. Does yours have it?

Yes, a feature, adjustable by the user. I’ll take another look but it’s been there for a while from my understanding.

don’t get me wrong jb4 is awesome but i fell into the black hole of messing w numbers for better throttle response. U could go back and forth messaging JB to figure it out or pay an additional couple hundo for a custom map6 w another company. So i opted for the cat6 just to simplify things. Both products are great tho

 

[CORHinO]

I’ve been super happy with the CAT6. Have taken it off and reinstalled twice without issues. Works as advertised, took 1 second off 0-60 times.

That's what I ended up ordering.

25 Ram RHO W MBRP CAT BACK EXHAUST, JB4 tuner & dual catch can, Eibach 2.7” ft & 1.5” rr lift riding on 37’x 13.50 x 20’s ………have the tune bang on runs like a beast!

Run 94 on custom Map 6 Beta basically tuned by AI then db checked with Burger……..

Sounds amazing couldn’t be happier but it took ALL LOT of screwing around but working nice now

 

[RamFan]

What does this mean? “have the tune bang on runs like a beast!”

Bang on?

JB4 Custom Map 6 beta 94 octane mods as mentioned

Boost is set by RPM

Fuel bias is set

Boost failsafe is set

Auto shift boost redux is set

Boost redux is set in gears one & two

That’s most of it, the Hurricane HO seems highly optimized making great horsepower & torque much more over stk pulls like a freight train

 

[crolzz]

SAFELY TUNED! No lean spots, throttle response exceptional, tranny shifts aggressively, but not overly aggressive,, it purrs as like a kitten or roars like a tiger, depending on where the pedal is

Not tuned for ethanol as they only use 10% in Canada, but 94 seems to work good

 

[D&Sadventure]

I’m more curious about this.
“basically tuned by AI then db checked with Burger“
AI tuned?

 

[crolzz]

OK, what you do is log a run on your JB4

Then email it to yourself

Then talk to AI tell them about your truck what’s been done to it that you’re running the JB4 which map, etc. what kind of fuel any other modifications ask if they would take a look at your logs at first they will say they can’t but they will copy and paste your log to AI. They will tell you what’s going on make the changes they suggest re-log send it back to AI then send the log over to Burger to make sure everything looks OK it will give you a custom tune if that’s what you’re looking for

Burger really does not suggest this, but it is a hell of a lot easier than trying to communicate with Burger all the time but always check with them when you think you got it dialled in

It’s pretty interesting. Check it out.

Which AI interface are you using?

Google. You have a JB4 you are struggling with a little bit?

I would stay with the beta firmware download the latest from the app

Alpha firmware is a little more likely to throw codes

And this is why I switched to the CAT6. If I have to worry about throwing codes because I’m not on the right firmware alpha/beta whatchamacallit, then it’s a no for me.

 

[crolzz]

Yeah I get it nothing is perfect these engines are over built for the twin turbos & are craving a good tune no matter how you get there, the built in failsafes with the stock ECU & with the tuners also make it pretty hard to screw anything up.

JB4 apparently adds just over 100 rwhp it feels like it but all the increased boost/torque can be hard on the tranny but can be easily tuned out so it works well.

Remember these are just piggyback tunes fooling the stock ECU into making more boost, torque and horsepower

There is certainly some potential here with the inline 6. My trx's best uconnect times were 3.4 and 9.7 with intake/exhaust/pulley paired with cold temps/1/4 tank/factory tires.

The RHO's best was 4.7 and I never did a 100mph pull. Today in the heat/full tank just the cat6 it did a 4.1 with a 10.3 on map3.

I’m selling a JB4 if anyone is interested

Was that with launch control or brake boosting?
