JB4 for 2018+ Jeep Wrangler/Cherokee 2.0L

[Terry @ BMS]

Working on setting this thread up. A lot of the information below is from our Alfa JB4 which shares the same engine platform and will be updated with Jeep specific information in the near future!

By default the JB4 ships on map1. For higher boost map, logging, firmware updates, and other features, you'll need a JB4 Mobile adapter for wireless connection to your phone or a BMS data cable for wired connection to a laptop.

Brandon at Krazyhouse Customs dyno testing our new Jeep 2L JB4 out on his dyno. Solid results on 93 octane vs. stock and got even better on an E30 mix! Will post the E85 mix runs after we make a few more tweaks to it!

[JHOOPS2]

One of the things that I missed when I got rid of my 135i (N54) was the JB4 and it's simplicity... Now that I have a 2019 JL Rubicon... BMS will soon be back in my life! Thanks Terry!

Logs from Jeep

Hi Terry,

Here are a couple logs. 91 octane (best available locally).

Jeep feels strong.

Also found this which makes a good place to mount the JB4 close enough for the OBD2 wiring to reach.

JL Audio SBA-J-JL-FHB - Jeep Wrangler '18-Up Accessories

[Terry @ BMS]

Looks normal to me for the platform. Have access to E85? You could mix in a few gallons to get octane up for comparison.

Hi Terry,

Will a test pipe trip the CEL? And if so I guess a piggyback can't really deal with that can it?

This just came out and looks like the first step to get some more power....

Yes, that will cause a CEL to come on.

MAP8 on my Rubicon 2.0T my 2018 (European Version)

I have tried the MAP8. This map puts the engine in safety mode.
The maximum speed is 50Km / h.
But it does turn on the engine light and then it doesn't go out anymore.
With the engine light on, maps 1-2-3 no longer work.
Why?

Yes, that's called Valet map. Makes the car super slow so when you give it to valet driver they wont go on a little drive with your car.

Put back in map 1 and turn car off and on and it should be back to normal.

[Terry @ BMS]

I have tried the MAP8. This map puts the engine in safety mode.

The VALET map is still a work in progress. Record a log on map8 (when the light isn't on) and we'll see if we can tweak it next version to run slow without triggering an extra light.

Many thanks, but I don't think to use the Valet Map.

In any case, as soon as I select map 8 the light turns on.
Then it is difficult to turn off the light.

Air intake system

I have tried all three maps, and with the standard air filter they work really well.
If I install AFE Filters 50-70035G Momentum GT PRO GUARD 7 Air Intake System, it seems to me that the engine pushes less. Could it be true?
Thanks

[Terry @ BMS]

Have a log before and after the intake? Let's see how they look. I really doubt the intake hurts. Although it may not help either.

No, I have nothing, how and what should I do?

[Terry @ BMS]

Use a dragy to do 1/4 mile runs on stock intake and aftermarket to log and compare differences? If no gain return the intake.

I found a test of a week ago, maybe a 0-100 km / h
2020-01-26 10_50_54_Map-3.csv (with standard air filter)
today I did 2 more tests
2020-02-04 13_18_08_Map-3.csv (with AFE air filter)
2020-02-04 13_19_52_Map-3.csv (with AFE air filter)
Can you see if it's better or worse with the AFE filter? :arco::arco:

[Terry @ BMS]

It looks the same to me.

There is one logging parameter missing currently we need to sort out to better evaluate intakes, charge air temp!

Yes, I have seen that some data is missing.
Even the gear.

Anyway thanks

Hey Terry the factory intake pipe has some resonators that seem to help torque down low before boost comes on.

Most of the aftermarket intakes get rid of them for a nice smooth inlet pipe. But as a result the Jeep doesn't pull hard until into boost.

I had a S&B and that was the challenge. Felt soft down low but I did see more boost at peak over stock - so it was helping, just not where the big heavy Jeep needs it the most

Any ETA on getting ICT working?

Also any experience with the AC intercooler fluid chillers?

2020 Cherokee

Has anyone done this on a cherokee yet? Was reading on another forum they are much more locked down and this won’t work.

This ! Waiting to order till i see a review in a Cherokee

[timberwolf]

I just ordered this for my 2019 Jeep JLU Rubicon. Looking forward to reporting back.

[timberwolf]

Any updates??

Sorry for the lack of feedback. The Jeep picked up a nice bump in power. Clearly more grunt across the range. I floored it behind a jaguar suv that merged full throttle and he didn’t pull away. My fiancé said the rush reminded her of our ess tuned x5 50i! I know the x5 was much faster but she got to sinking stomach feeling from the passenger seat so that’s a great sign! 😂

Sweet i literally just got mine in today for my
Cherokee 2.0t. Was the install easy??

[Payam @ BMS]

Super easy install, won't take more than 30 minutes for your first time. After that should be 10 mins!

Is there a guide ? Or instructions ?

The install guide is on our website.

I’ll take pics on install and make a video my engine bays a bit different than a wrangler!

[Terry @ BMS]

OK great, post up some photos here and we can add them to the guide also!

[yellowssm]

Does this work with both the 2.0t and 2.0t with torque?

[Terry @ BMS]

Yes all 2L Turbo motors.

I have a JB4 on my M5, if I order one for the Jeep, can I transfer the bluetooth module from the M5? Basically is it the same bluetooth module for all JB4's?

JB4 Issue

Hello,
I installed the jb4 a few days ago. Since then I've had problems with map 1 through map 3. I have attached all of the results including map 0

The JB4 is the only modification that is on my 2020 Jeep Wrangler Rubicon 2.0L.

Any ideas on what could possibly be causing what feels like a cut out while acceleration from 0-60?

Thanks,
Cody McNeal

What fuel are you running?

[jeep2.0L]

What fuel are you running?

I got the jeep new, never have put anything less then 91, I'm at 7,000 miles.

[Terry @ BMS]

If map1 isn't working no need to go up to map2 or map3.

Let's try this next. Set map6 values to 2.0 across the board, and log map6 for comparison.

Ok, I’ll try that and report back this evening. Thanks

Any updates on E85 map tweaks yet? Excited for this

[Terry @ BMS]

We have a few customers running E30 without issue but it's still being tested. If you have access pump a few gallons in and evaluate. It should benefit each JB4 map.

[209hunter]

I’m having a stutter/hesitation when I first roll into the throttle. Especially when the Jeep doesn’t downshift (high load and boost, lower rpm). I have a ******* ********, 3” catback and intake. Running 91 octane with a bit of e85 (roughly 20-25% ethanol). Not sure if these logs show the issue. If not, let me know what to log. It seems the actual boost overshoots target boost on initial throttle tip in and turbo spool. And then you feel like timing is being pulled.

[Vinniechin]

Couple questions. I just ordered.

I got the Bluetooth feature. We now have to download the app for $28?

Second question. Map1 is for 91 octane and map 2 for 93 and map 4 is for e85 mix?

I want it to be a safe tune with no worries. Can someone help educate me on this?

Thanks in advance.

Yes you need to pay for the app

Map 1 is always the 91 octane map. I don’t know about the other maps.

There is a lot of safeties built in to protect your motor.

Yes the smart phone integration is $169 for the adapter and app.

What fuel are you planning on using?

[Vinniechin]

Thanks Terry. I will be running 93 exclusively.

Any guidance would be appreciated.

I run this on my Q50 and this forum should be much busier than it is!

Great product and I will be a proponent for sure.

93 octane only. And will the app allow me to Data log? I already bought the Bluetooth adapter from you.

Thanks.

Vinnie

[Terry @ BMS]

Yes the app is for logging, map changes, setting changes, firmware updates, etc!

For 93 octane map2 is likely the best fit but a log will confirm.

Thanks Terry. Once I get it and install I will eventually post a log.

Still breaking it in with 200 miles on it and who knows with the stuff going on when I will finish break in.

I appreciate the quick rely.
