What settings are you running on the JB4? Are you running the BCM as well? What firmware are you on?

No one makes a BEF for us. I asked my tuner, Halim from HCPerformance and he said my tune should work nicely with my JB4, which it seems to be doing so. I've asked MHD if they'd be interested in a helping create a BEF and they declined.

How are the turbos blown, like you're no longer getting boost, they're seized, extreme oil consumption (which can be relative to the user), etc.

Very interested to hear what is going on here. I hate to break it to you, but the JB4 is not what ruined your turbos. Where in the US are you located? Perhaps I can direct you to somebody that may be able to help.

FF and Duty Bias tuning is difficult on this car. Not as clean cut as the n55/n54 application. If you are not able to work with the JB4 on this platform, that's fine. We all are sorry you head to deal with the headache. If you want, you can come to Texas and I will help you attempt to resolve the issues.

In my experience, due to the finnicky nature of the motor, most problems are a combination of an iffy duty bias/ff setup (not an actual JB4 issue), mated to physical issues on the motor.

Long story short my motor brand new (blew motor when I bought truck) kept going back and forth to BMW for numerous things vacuum pumps alternater secondary water pump ect I could go on for days.. turbos have oil everywhere as my guy from BMW said (idk how to upload pics here or I would) felt like truck was crapping out at 60-80 mph almost felt like burn plug or something around that feeling.. reason for getting rid of jb4 is I have no help with it nor does anyone I know mess with this thing.. loved it at first felt the power was easy to switch maps and loved the jb4 app.. I was told piggy backs just trick dme to do what it's telling it but doesn't always work ( one day I'm flying next day truck is a slug) and last reason to get rid of it is burger will not help to even look at a log I've even offered to pay them and they declined.. if u don't stand behind your work it shouldn't have been produced In first place.. in willing to keep jb4 if anyone has ideas.. I'm in New York thanks for response guy thanks for any help u could give me

While I agree it sucks that the support has ended, it's a night and day difference when running maps 1 or 6, which are currently the only maps I use. I'm not saying it's not the cause, but I doubt it's the JB4 at this point unless you were pushing mid 20's psi and blew seals out, but even then I get overboost errors on anything over 21psi, so I'm not sure how you'd get more without hitting the same issues I do.

If I remember correctly, Burger Motorsports never fully released a JB4 for the N63/S63 platform. Terry might correct me, I don't always read the updates. The product was always available and still is, only in it's BETA form. There is no more development happening. There is no more support. The choice to use the product is on US, the end user.

It's okay if you don't like it, nobody has hurt feelings. I personally think you should keep the jb4, and also search for a custom tune. The JB4 is still great in regards to data logging and other things.

I'm here to help, but you haven't even fully disclosed what the problem is. It sounds to me like you have had a lot of issues with the engine in the car, so I don't understand why you are so quick to blame the JB4. I don't even know what the problem you are having with the car is. You're saying sometimes you are boosting properly and other times not, correct? Post a log of the car boosting, and post a log of it acting up. I'm happy to review and offer advice.

Does anyone have experience with knock sensor codes on the S63? I'm getting "Knock Sensor 3" code constantly right now. Doesn't matter if JB4 is off or on, or on what map. It started after the JB was installed for a few days, so my first troubleshooting step is removing the JB and seeing if it goes away.

It will come on almost as soon as the car starts, and comes back right after clearing. At this point I'm thinking it's probably a bad sensor, but I can't find much info as these apparently don't go bad often.

I'm thinking if it was a bad coil/injector/plug, I would be getting misfire codes, not knock sensor codes.

Any tips from someone with a similar issue would be appreciated.
I did not initially see this post.

Bad news is, knock sensor faults are often knock sensor problems. Double bad news, you have to remove the intake manifolds to take the knock sensors off the car. Easiest way to do this is lower the engine out of the bottom. Not a big deal for a shop with a lift and hydraulic table, kind of a PITA for the average DIY guy.

Seems like you might need to find a shop to do the work boss. Book time on the job is 15.5 hrs for the left side and 13.0 hrs for the right side. Not a cheap repair. While they are in there, you should have all of the PCV/Breather Hoses/Valves replaced. There are two hoses that run down to the manifolds and back up to the intake, if nothing else replace those two while the work is getting done.

Just installed the system,
Two things that someone might help with.

1. Fsb is turning meth pump on whenever you turn ignition on(checked with multimeter)
2. Bt kit disconnects after working few sec when i start the engine

Any ideas

Thanks?

Was this originally an S63 JB4 or an N63 version flashed over to an S63? I haven't finished my meth setup but I haven't had that problem with my BT.

Which firmware are you on? Seems there's been links with BMS trying to be emissions compliant as pther things are coming up. I'm not sure if it's still posted on here anywhere, but you can email me at m5james@yahoo.com to try and flash an older firmware to see if you get the same issue...for process of elimination purposes only.

I have 3B as well, will check that and if no success i might ask you for other version, but other reason behind fsb behavior might be that it is jut defective, i will get one from my 135i today and swab to x6m to see if that was the case.

thanks in advance

Set menu1 to 0 to disable auto clear, 3 to enable, if firmware has it equipped.

Yeah that's my fear as well. I can have my indy do both sides for around $750 (hell of a deal for disassembling the entire damn truck). Have an appt with BMW tomorrow to try and verify it's actually the sensor before I spend the coin though.

It's nice having the turbos up top in the V, but jesus **** it makes this engine a PITA to work on.

Try the BMS data cable instead of bluetooth. I had a ton of weird issues before I just went to the cable. Note you also can't use any normal serial->USB cable, it has to be the BMS one.

What settings changes have you made? Curious just for the sake of seeing what I might try.
