Hi everyone!

I'm new to this forum and wanted to know if I only need the BCM connections because the gearbox always opens the wastegates and thus regulates the boost pressure down when the boost gets too high. I am asking this question because i already have a transmission tune on my ZF8HP80Z which deactivates the boost pressure regulation in any gear.
If this would be the case, i would not need the BCM to be connected, right?

Btw i have a 2013 BMW 650i xDrive (N63TU).

Thanks for the help in advance and greetings from Austria!

So are fuel wires no longer a option or is it one of those things you can do but unsupported? Iíd like to see fuel pressure readings

Hey guys I’m new to this forum but not new to JB4, I had some questions I just turned my 2021 M550 and installed down ***** as well. I was curious on what map you think I should be running my vehicle on? Right now I am running it on map 2 but I think it can definitely get more power with a different map.. any help or suggestions would be great

Hello
I have a 2015 X5 xDrive50i with the n63tu and thinking about getting JB4

What type connector will i need?

Does it still having steering wheel controls like older versions? or will i just have to use the app?

This is actually G series, but I'd like to hear from Terry on this also. I've heard a few people with the N63TU3, 5, 8, and X series, saying that the gains were very underwhelming, which I don’t like hearing when they bought off my recommendation. Thinking the TU2/R firmware may not be optimized for the TU3.

I haven't installed my JB4 yet, waiting for the EWG harnesses, but considering how much the stock TU3 seems to like ethanol (I'm on my second tank of E25), E25/30 could really wake the motor up with a custom Map or firmware.

Mike Levy - I have driven in a 2021 m550i with ********* and the JB4 and I would have to say, whether it was just from the *********, or both, the car was considerably faster than my 2021 M550i. I was very impressed.

I see you're waiting on EWG harness, is that to achieve more power with running your E25/30? Also I don't see the EWG harness available for our engines?

Since we're limited on our 2021 m550s, I too would like to hear what Terry has to say about making more power.

I dunno. I haven't driven one with the JB4 yet. All I can do is report what people have told me.

The EWG harnesses are because on the later cars the wastegate connectors are upside down, so we can't plug them in. The harnesses will flip them. They haven't been released yet. The N63TU3 can run up to E25 from the factory.

Okay gotcha. Thank you for the reply Mike.

Hi !! Im about to install a jb4 on my friend bmw m850i 2020 and i read somewhere that for the basic installation i juste need to install two of the connector to the intercoolers and the one that go to the obd2.

On the site they installation is showed on what seems like a older version of this engines. Is there a walk-through for the newer version ?

And we dont need to remove the power from the battery when installing the units ?

This is G-series, not F-series.

The connectors are on the intercoolers in a similar place to the older models (see attachment). On the drivers side you need to remove the cross brace and the airbox lid. If you have big hands you may need to pull the whole box. The passengers side sensor is on the front of the intercooler near the bottom and can be accessed without removing anything.

Its always a good idea to disconnect the battery, but I don't know how much it really does. These cars have 2 batteries. One in the trunk and one under the passengers side cowl. Disconnecting both screws with the adaptations and memory features, so its really not something I'd suggest doing.

For some reason the JB4 will not target anymore than 25psi. Iíve tried both map 8 and map 6 . Upgraded turbo car stacked with bm3 flash.

Yo_Holle 06-30-2021 05:43 AM

I have a N63tu Jb4 with V2 board and want to run map 7, Do i still need add the fuel control wires and if so how do i attach them?

l1nk3d 11-03-2021 08:47 PM

I'm not sure if anyone is still in here or monitoring this, BUT, I purchased a JB4 for my 2012 E70 N63 and just traded it in for a 2017 F15 50i N63 (not sure on the exact engine code yet). Looking at the intercooler sensors they look the same, but I can't find an install guide that matches my engine configuration.

Will the JB4 work with my F15 and I can just download the maps accordingly or do I need additional/different connections?

BeGooD69 12-02-2021 07:10 AM

Do we need to use a BEF to install 3.5tmap or could we setup on jb4 alone like on n54 platform?

Mike_L 12-02-2021 03:33 PM

The user settings on the JB4 allow you to program the 3.5 BAR TMAP.

Thx Mike.
I installed some and put tmap =1
No codes for TMAP. I assume it worked good.

BeGooD69 12-05-2021 06:44 PM

Where can i find the steering controls. I am not familiar on haor to do the map switch on the fly. Im only able to do ot with JB4. Any videos on how to use the controls out of the steering wheel. How to get into the menues. Thx

BeGooD69 12-28-2021 04:08 PM

Any help on those steering wheel controls please?

The BC control is limited and not supported on all models. But it's fairly easy to use. Similar to below.



'***************************************
'OBDII In Dash Menu
'***************************************

'0 map menu, map shown on tach (tach shows Map)
'1 Active Sound delete (for models equipped)
'2 Boost gauge on fuel, scaling in dash is 0 to boost safety setting, turns on when gas pedal is pressed 60% or more and turns itself off when you resume low throttle use. (tach = 0 OFF; tach = 1 Boost Only; tach = 2000 Boost on fuel, Meth on speedo ring; tach = 3000 Boost on fuel, Timing on speedo ring; tach = 4000 Boost on fuel, AFR on speedo ring)
'3
'4 Delete Fault Codes
'5 Dash Mode. tach = 1000, SAE; tach = 2000 Metric
'6 1st gear boost limiter. (Tach = boost cap / 3)
'7 2nd gear boost limiter. (Tach = boost cap / 3)
'8 3rd gear boost limiter. (Tach = boost cap / 3)

Thx you very much.

Next thing i have is: i dont see AFR2 and Trims2 not sure what the issue could b. Could u please review and feedback on the attached file.

I think i have my settings wrong, any input will help. For now map1 just to start safe ish until i get it all figured out.

Setup: 93oct, cold air intake, d@#% p!&€$, jb4/bcm installed
(Maf sensors unplugged as per install instructions)

Thx you

Log seems fine. We don't have all app channels active on the platform.

Good just wanted to make sure it was normal. Now we can test map 2 and see..
Then xhp notice difference..

Thx Terry

Wondering if you have any recommendations for shops in the Chicagoland area that install a JB4 for a 2022 M50i vehicle?
