This thread will be the single source of information for everything BMW B48/B58 JB4 related! Note both engines use the same hardware. The JB4 will detect the different during installation and map accordingly.

Map Guide as of v8 firmware:

Map0: Stock tuning, fully disable JB4
Map1: Additive map with peak of 3psi over stock added (91 octane)
Map2: Additive map with peak of 4psi over stock added (91-93 octane)
Map3: Additive map with peak of 6psi over stock added (93+ octane)
Map4: Stock tuning with CANbus features active
Map5: Additive map with peak of 6psi over stock added & more aggressive timing profile for higher octane fuel (experimental, 93+ octane, bolt on modifications)
Map6: Custom tuning map allowing both additive (below 10psi) and absolute (above 10psi) targeting
Map7: WMI map (boost varies based on WMI additive and map settings)


Firmware:

BMW_B48_B58_OBDII_11_TEST1: Click Here for Firmware --> Attachment 79545

1) Potential fix to diagnostic code clearing bug that has cropped up with the latest software builds.
2) Adjustment to absolute target mapping, lots more testing needed. Send in some logs if running absolute target maps like map7.


BMW_B48_B58_OBDII_9: Attachment 79544

1) Redesigned CANbus logging engine for faster sample speed and all available parameters including cyl1-6 timing, water, oil, and trans temp, full time.
2) Corrected speedo calibration issue when using in dash menu.
3) Added FutureUseD Bit4 option to disable startup sweep.
4) Added in dash timing and AFR gauges under menu 2/3 and 2/4 respectively.
5) T2 - Fixed bug with fault code reading.
6) T4 - Fixed possible bug with alarm engaging.

BMW_B48_B58_OBDII_8: Attachment 70252

1) Adjusted map numbering per above!
2) Removed intake temperature signal adjustment from map1. Option is now available for map6 or map7 using the 6cyl timing field. 0 disables it, value of 10 increases IAT sensor readings lowering timing, value of 70 decreases IAT sensor readings increasing timing. Adjustment active on maps 6 and 7 only. Experimental feature.
3) Adjusted additive maps so they can be used without OBDII cable

BMW_B48_B58_OBDII_7:

1) Added CANflap operation to allow control of the factory exhaust flapper from the drivers seat. Press the BC button for a second to change modes. Left arrow is flapper open full time, right arrow flapper in OEM operation which is generally closed unless at full throttle.
2) Internal CANbus changes to improve speed and operation.
3) Groundwork for virtual flex fuel sensor added. See E85 FAQ below.
4) Wastegate dutycycle offset for cars with modified exhaust that experience excessive throttle closure. When equipped with an EWG connector on the JB4 harness FutureUseA can be used to apply a static negative offset. Generally a value of 30 is a good starting point.

FUD:
bit0 - Disable in dash BC button controls
bit1 - Disable wastegate adaption.
bit2 - Full time IAT spoof (for testing)
bit3 - Raise "boost over stock" cap from 10psi to 20psi.
bit4 - Disable startup sweep
bit5 - Disable CANbus when boost is less than 1.5psi
bit6 - Unused
bit7 - Force actual boost value out MAP sensor (for testing)

FutureUseA: Negative offset to dutycycle via EWG connector to correct for over boost conditions when PWM is low


FAQ

Can I run E85 with this platform?

E85 can be mixed in but with trade offs. The BMW B48/B58 platform has an internal fuel cap that causes the DME to reduce it's internal boost target as fuel volume increases above expected levels. Since E85 requires a higher fuel volume the net result is a lower boost target. While small mixtures of 10-20% can be used to increase lower octane fuels expect a little less boost when running it. If equipped with the factory PPK tuning the internal fuel limit is higher and you can effectively get away with a little heavier ethanol mixture.

What is the optional EWG harness for?

This plugs in to the JB4 connector using the same directions as the N55 EWG plug (purple in #9, blue in #16) and allows the JB4 to increase or decrease the wastegate dutycycle directly. Cars running a WMI kit may benefit with the JB4 being able to more effectively add boost. While those with certain exhaust modifications may benefit from having the JB4 reduce wastegate dutycycle to prevent boost creep and throttle closure. In most cases there is no benefit to adding in this optional connector. After attaching pins to JB4 harness plug the EWG connector itself to the factory plug on the wastegate by removing the airbox and unsnaping the heat blanket covering the EWG assembly.

What is the optional fuel pressure harness for?

This plugs in to the JB4 connector (green wire goes in #21, black wire goes in #4, fuel pressure plug attaches to fuel pressure sensor under engine cover) and allows the JB4 to both datalog high fuel pressure and also offset the fuel pressure signal back to the DME adjusting fuel trims. This sensor DOES NOT increase the DME's internal fuel limit or its tendency to reduce it's boost target as fuel volume increases. It is suggested for correcting fuel trim issues in unique situations like for a larger turbo, heavy E85 mixture experimentation, etc. In most cases there is no benefit to this optional connector.

Is WMI (water methanol injection) compatible with the B48/B58?

Yes! In addition to increasing octane WMI also supplements the fuel system allowing more boost and a richer air/fuel ratio under the DME fuel cap. Installation is the same as the F series N55. FSB blue goes to #14, FSB orange goes to #3.

Random Development Timeline:

6/18/15: Just placed an order for a Mediterranean Blue metallic BMW 340i automatic. It will have the new B58 engine which I suspect will be very similar to the N55. But we'll find out in 2-3 months! Car is being made in the South Africa factory. Hope they do a good job of it. :drinking:
11/27/15: Finally showed up! Only took six months lol. Will get going on some baseline numbers and tuning next week!
11/28/15: Got a JB4 B58 Prototype up and running including full CANbus control!

thats awesome hopefully it has some potential

BostonShant 06-18-2015 01:12 PM

That's awesome dude CONGRATS!!

I have a feeling these things are going to be pretty quick. Looked like a tubular manifold with a twin scroll. looks promising but time will tell.

would be fun to see the tuning difference in the B58 vs N55

a fun read

What other options did you get?

If that thing makes more power than our n55 easier I'm lighting my car on fire

Backup camera only. I rarely get any options on the development cars. :)

No M-Sport to get rid of the 130mph limiter? :eek:

Didn't you learn your lesson with the N55 135i? :lol

Can't wait to see it but where the heck are you going to put it?:popcorn

Interesting article, air to liquid intercooler and a mechanical water pump..

CHECKERED 06-19-2015 07:51 AM

I really like the design of the turbo manifold, almost looks like an equal length,

does it look like the exhaust side will be a 4" down-pipe?

katsooba 06-19-2015 08:33 AM

im sure everyone are wondering if the turbo manifold fits the N55 ;)

Vorsprung_CJB 06-19-2015 08:54 AM

Can't wait to see what this thing can do. Oh man I hope they make an M240i.

lol I know. The N18 MINI and 2011 white 335i are both scheduled to be decommissioned soon. Should free up some spots. :)

Hi Terry, it will be better than you expect. High standards here. Maybe we will throw in a water/meth system aswell.

This is exciting news! Leave it to BMS to be on the leading edge for development.

This caught my attention also. I'm indifferent to the intercooler, but the mechanical water pump should live longer than these electric ones.
The rear timing chain sounds like the pita.

Just put a $1000 water pump in my 135i convertible at 70,000 miles. My mechanic was mildly impressed it lasted so long.

Two months ago I put a $70 water pump in my 10 year old Nissan truck at 175,000 miles - my first repair outside of three batteries, oil, and brake pads.

My 135i is pushing $30,000 in repairs in the first $70,000 miles. Worst car I've ever owned by 10x, but thanks to Terry at least it's fun!

I've only had mine for a short time. I've encountered a few issues, but so far (knocking on wood) nothing I couldn't take care of myself.
enjoy driving it, and am looking forward to a few more upgrades. Jb4, and filter were my first, now contemplating a ********. (Noise vs power)
