I have a 2013 X5 50i. Can you help clarify a couple things. If I buy a JB4 stage 1, I can run map 1 or map 2. Map 2 gains are around 40HP and 40TQ?

Also, is there any recommendation for a flash tune to run with the jb4 to get a little more out of it? Are there OTS flash tunes I can use like I have from MHD for my n54?

I'm not looking for anything crazy or unreliable. I was hoping to get around 75HP and 75TQ out of this thing with a tune.

I installed a BMS stage 1 to JB4 upgrade with BCM 3 years ago and can't find the wiring diagram with pin connections. Can someone please post a link or email?

Thanks

Default N63 Firmware - 04-22-2020, 07:40 AM

Hi,

Can I use the JB4 N63TU with a N63 engine if I update it with the N63 firmware?

Depends on the vintage. Newer N63TU systems are PWG v2 and would not be N63 compatible.

Thanks for the reply.

If I buy the current JB4 for a 2013 550 (N63), can I buy the mobile wireless option or I have to use the BMS wired connection?

Just sold my 2012 650i and picked up a 2015 550i. Will I have to independently sell my fairly new JB4 and pick up another one or can it be swapped out for credit towards a new one?

Default Drivetrain malfunction at wot - 05-23-2020, 06:19 AM

Ok guys, Iím new to this, and I want to figure some things out. I have a 2012 550i, and Iím getting a drivetrain malfunction. Looked at the code and it says air mass flow too high? So Iím guessing I have to change my tmap sensors correct? But Iím also looking at the boost Iím running on map 2 and it only hit 16 max. I have Arm car less *********, Megan axle back exhaust, and diy front mount intakes. I data logged it so that you guys can see and let me know where am I going wrong.

Yes for MAF code change the MAF sensors.

Boost looks normal to me.

Thank you for the quick response, I will try to get that done today, if not soon. How would I be able to push around 20 pounds of boost. That is what I’m aiming for

N63 life so you have limited options. Look in to a flash tuner to get you clsoer and use the JB4 for fine tuning, logging, boost by gear, and safety.

Sooo.... after I looked over the logs I sent to you, I noticed the boost spiking, so I’m thinking that’s when I get a drivetrain malfunction. I saw there’s somewhere in the app to change boost spike between shifting gears. Can you tell me exactly where and how to do this? I’m still running tmap 2.5 sensors, and any map other than 0 I get that drivetrain malfunction, when I’m boosting too high. But I feel like there’s a problem with spike, so while I’m running map 3 I don’t want to over spike and hit detonation. Please give me a solution. Let time though told me tmap sensors but they haven’t arrived

There are no useful adjustments for that on the N63 JB4 as it does not have wastegate control. The N63 is simplified to the point now that a JB4 itself can't cause any tuning issues on map1 or map2. Because we don't want to deal with the headache of N63 support trying to run higher power levels. We'd need to charge $3000 per N63 JB4 to make it worth it.

If you have MAF faults the fix is to replace the MAF sensors.

Default Drivetrain malfunction - 06-19-2020, 07:39 AM

Getting codes 122104, 122004, and 120408... only on cold starts.. once the car warms up and stays warm I can clear the codes and wonít come back till next cold start

Theyíre related to diverter valves, however Iíve tried replacing the diverter valve with turbo smarts plumb back diverter valve to no success, is pulls the same codes..

Iíve checked the voltage of both solenoids and theyíre in line, also the passenger side diverter valve doesnít have issues..

Just did a compression test as well everythingís 195+

I feel like Iíve tried everything to diagnose/fix the issue..
Any insight would be fantastic as I took it to bmw yesterday for a diagnosis and paid $160 for them to reiterated what I told them was wrong before their diagnosis.. all they said is replace the diverter valve and Iíve done that twice..

Mods:
3.5 MAP Sensors, N63 Intake, VRSF ******* *********, xHP transmission tune, turbosmart dual port diverter valves, JB4, n63 oil sport cooler, 3 inch straight pipe

I don’t believe they’ve been done yet and I’m at 80k miles so I should probably change them, however it has never thrown any codes for the Vanos system..

Doesn’t have a rough idle, only thing is when I’m in neutral or park and rev it, car does shake from 2300-2900ish rpms..
Also just replaced engine mounts 8k miles ago..

Looks like I’ll be pulling mine as well

Question 06-27-2020, 05:44 PM

Hello Terry, just saw that on the JB4 app we can update to N63_4_T1 and here you are still pushing N63_3_T2...

What are the differences and is it a bug in the app?

Also, 2 ę*problems I have:

I just got an ARM intake and I am getting rough ignition on low rpm and sometimes I get a CEL for rich mixture. How can I play with the AFR to get it to stay happy all across the rpm range?

It seems that I have a 2-3psi difference between bank 1 and bank 2, is there a way to adjust this?

Thank you

Only P0175 / 118102 for the rich fuel mixture. The MAFs are installed correctly and in the correct orientation (checked twice) and are correctly plugged in. I really donít see why Iím getting a rich AFR, plenty are running these intakes without issues (goddam N63 platform and itís gremlins)

The worst part is the way the engine runs at low throttle or on cruise control, it seems like itís always misfiring and hesitating but no misfire codes and no codes for injectors either.

Once in a while I get the code for my ca_t_less down_pip_es but thats normal

I was getting codes like that after my n63 intakes and jb4 install . Swapped the map sensors out with the harness and it cleared everything up

You mean swap them from bank 1 to bank 2 and so on or replace them?

They are brand new with barely 100km on them and everything was running 100% before the intake installation
