Default Pure turbo stage 2 and JB4/MHD - 04-28-2019, 07:30 AM

Hello all, first post for me.

Having a 335xi E90 2008 N54 with 125K miles on it. I'am planning to install Pure stage 2 turbo upgrades in two weeks.

I'am FBO, MHD back-end flashed as well as an updated JB4. I'll be installing inlets, DVs and a new water pump in the same time.

I'am fueling with 91 since a don't have access to better fuel in my town. It's my DD.

My question: Do i have something to adjust on the JB4 in order to target the proper boost? I'm planning to leave it on MAP5.

Thank you for your comments/answers.

What is an updated jb4? Like latest software? Or did they make a new jb4 after the g5?

Hello Maniac,

Yes, it's with the latest firmware. Maybe it's not that relevant.

The answer is yes. I had asked that question on one of the forums before.

Yes for lower grade fuel the same base BEF Is used even with hybrids. And then you'd want to post logs and we can help you evaluate it from there.

I updated my jb4 with the Bluetooth kit I just purchased and I saw on the notes it said I had to do everything with certain map settings. So my question is when I go on the app at the top it says map 6 configurations so do I need to be in map 6 before doing the update because now I am getting the dreaded boost leak code

Probably the wrong place but I looked, if my girl’s JB4 is installed correctly, firmware up to date, set to stock dme settings (4/3 I believe), put on map zero, and throws an engine malfunction code that is doesn’t throw with the JB4 installed, that is clearly a problem with the JB4 (bought used) and probably needs a new board yeah?

EDIT: the user adjustment setting have been reset accordingly as well, I know I did it right because I did the same thing to my 135i the only difference is she has a 335i. Both N54

Did you test that JB4 in your car too to see if it causes the same engine malfunction?
That would answer your question whether or not the board is fried or her car actually has issues

That’s what I’m about to have to do but I was just trying to get a second opinion.

Edit: took the JB4 off and the car works excellently now. For some reason it wasn’t boosting at all according to a log I took right before I took it apart and now it’s good. So I’m assuming the board is usually the first thing that I should replace seeing as the harness looks fine, but ima take it apart and look at it. Anyone have any input on how obvious it would be to see where/if it’s messed up?

Good morning. I have also just installed rb turbos on my 335 n54 and have FBO and bms WMI. Running 91 octane. With bms bef.

My question is probably stupid but please bear with me

When Terry says to enter de default hybrid turbo settings, does this mean to run map 6 with these settings?? Or still run map5??

Please be easy on me. I am new!! Thanks in advance guys!!!

Once hybrid settings are entered you continue to use any map you want. I'd start slow like map1 to ensure it's all working as it should be.

For NLS on new firmware manuals need to make sure that auto shift reduction is set to 0 so the JB4 knows you are manual trans.

Hello all, first post here. Been running JB4 with firmware 32/8//2 for almost a year now (purchased JB4 last summer) and recently updated to firmware 32/14//2 and noticed a couple odd gauge behaviors that weren't happening before.

One is that the gauge sweep sometimes happens several seconds after startup when taking off (manual trans), this doesn't seem to be consistent on when or if it happens.The other thing I noticed is that going from a fuel gauge hijacking option (ie boost on fuel) back to disabling fuel gauge hijacking, the fuel gauge will just remain on empty until I restart the car when it will go back to reading the fuel level.

Curious if anyone else has noticed similar behavior or if it's something I'm doing wrong?

Hi, I keep getting ALL cylinder misfires on WOT only above 5000rpm.

Have RB turbos on 100% meth, FBO, upgraded LPFP.

Tried NGK 2 step and 1 step colder plugs and stock plugs. No change

New coils. Bimmerlife.

Injectors are index 12. Have replaced cylinders 1-2-3. Same results . Doesn't seem like I have issue there as no morning misfires due to leaks. And misfires are always on different cylinders or in ALL cylinders. Coded well and decouplers in place.

Carbon cleaning done as well.

Logged HPFP & LPFP with Trebila and everything is perfect. Logs are perfect until misfires.

Have stage 3+ spec clutch and flywheel.


No other codes. Just the misfires on several/All cylinders.

O2 sensors fairly new.

Any ideas.?? Anyone??

Both could just be bugs with the v14 firmware. I'll check in to the gauge hijacking not resetting.

On the gauge sweep is RPM dropping when you engage the clutch to trigger it?

Thanks Terry, I image the RPM drops somewhat as I let the clutch out to take off, I can't say that's exactly when the gauge sweep is triggered though.

I'll watch it more closely over the next couple days to see if I can narrow down what triggers the sweep.

Noticed this guage sweep on startup sometimes it sweep directly , other times it takes few seconds maybe 10 or 15 sweep after startup, thought my jb4 start getting crazy but possible its same reason of the above. By the way noticed this mainly after the upgrade of firmware which meant for the xhp and trans changes.

I watched it closer today, on a cold start the gauge sweep is delayed until the idle drops down below 1000 rpm (about 20-30 seconds after startup).

I tried starting it again a few times after the engine was warmed up and the gauge sweep happened immediately every time.
