Hey guys,

This is the central thread for all things related to the s63tu JB4 system. Including updates, directions, firmware, etc.

Note that the JB4 can be used with and without the Boost Control Module (BCM). While the JB4 installation is relatively simple, similar to our Stage1 tune, the BCM install is more complex and requires you to swing one of your intercoolers out of the way to access the boost solenoid connectors. If you're happy with Stage1 power but want to add smoother operation, CANbus features like an in dash boost gauge, diagnostic code read/delete, boost by gear options to improve traction, then consider starting without the BCM. You can always add it in later. On the other hand if you're looking for maximum performance the BCM when combined with the JB4 is a real game changer.

JB4 Interface: Latest Interface Download. When updating your interface you may need to first go to "add remove programs" and "remove" your previous JB4 interface.

If you need directions on how to connect a laptop to your JB4 to update firmware or how to datalog Click here.

Installation is the same as the Stage1 connecting to the TMAP sensors on the intercooler (DO NOT PLUG THEM IN TO THE MAF ON THE TOP OF THE ENGINE!) per the Stage1 installation guide: http://www.burgertuning.com/instruct...e1_install.pdf

In addition the CANbus OBDII wire must be connected per the directions in the 2nd post. And if equipped the BCM module is installed per the 3rd post.

s63tu JB4 MAP GUIDE AS OF v1.5:

Map 0: JB4 disabled
Map 1: 4-5psi over stock additive. Suggested for most pump gas applications with and without BCM.
Map 2: 22psi peak absolute. BCM required. In some cases we've found this map maxes out the factory fuel trims. In those cases only map1 or map3 can be used without meth injection.
Map 3: 18psi peak absolute.
Map 4: Stock map w/ CANbus enabled
Map 5: //M map ramping boost up to redline (BETA)
Map 6: Custom target map
Map 7: 25psi peak (e.g. race gas, BCM required)
Map 8: Progressive meth map. Peak boost based on meth additive. 0 = 19psi, 75 = 30psi. BCM suggested.

Note without BCM all maps, especially the higher target maps, will under target on boost.

S63TU Stage1 to JB4 upgrade directions:

You can order the upgrade kit here: http://www.burgertuning.com/N63_JB4_upgrades.html

For those with an s63tu Stage1 you can upgrade it to a s63tu JB4. The s63tu Stage1 to JB4 upgrade kit is $400 and includes a revised CANbus enabled JB4 board, CANbus wires for the harness, and an OBDII connector to plumb those CANbus wires in to the system in a fully plug and play way. We also suggest adding the aluminum or plastic weather proof enclosure.

If you are installing a full s63tu JB4 system install the TMAP connectors per the Stage1 guide and then skip to step#2 for routing the OBDII cable!

1) Disconnect the negative battery terminal in the trunk.
2) We're going to remove the back shell from the Stage1 AMP connector and insert two more wires in to the Stage1 harness. For those who currently have a methanol kit installed the wiring will also need to be relocated. The tricky part is that the wires can not be removed without a special DSUB removal tool so it's best to cut and splice them as needed. Reinstall the shell when complete.

JB4 wiring:

Green CAN wire goes in to pin 2
Brown CAN wire goes in to pin 15
FSB orange wire goes in to pin 3
FSB blue wire goes in to pin 16



3) Using a screwdriver pull away the felt circle and push in the rubber cap towards the passenger compartment. This is where the OBDII cable will be routed.



4) Push the OBDII cable from above and to the left of the brake pedal through the hole. Taping the end of the OBDII cable to a coat hanger or stiff wire can facilitate this step.

5) Plug the mini-molex connector from the JB4 harness in to the routed OBDII cable and tuck the extra slack out of the way.



6) Plug the OBDII connector in and route the wiring behind the panels.



7) Switch the JB4 circuit board for the previous Stage1 circuit board. They fit in the same enclosure. This might also be a good opportunity to upgrade to our latest billet all-weather enclosure: http://burgertuning.com/JB4_billet_a...enclosure.html

8) Reconnect the battery.

BCM Installation guide

Lots of addl photos are needed here. Some basic directions to get the ball rolling. Note the BCM pairs should not be mixed up. With earlier ones we plug them in to each other and with new ones we also add a zip-tie so you know which pair is which. If you mix them up the net result will be too much boost in one bank and not enough in the other. Bank2 boost is shown as "IAVG" in JB4 logs.

Also note we suggest installing the JB4 first, ensuring the vehicle operates normally/code free, only then moving on to the BCM install, to reduce the variables should you need to troubleshoot.

1. Disconnect negative battery terminal.
2. Insert the BCM BLUE wire in to the JB4 DB25 connector position #1.
3. Connect the ground fork to the shock tower or any other suitable chassis ground.
4. To reach the wastegate connectors you're going to need to loosen and pull aside the passenger side intercooler.
5. Remove the passenger side "charge pipe" from the top of the intercooler, loosen the hose clamp securing the intercooler to the throttle body, and any bolts securing the intercooler in place
6. Unplug the two large water hoses. A quart or two of coolant will leak out. I used tap water later to refill but OEM IC coolant would probably be a better long term fluid.
7. Rotate the intercooler out of the way exposing the two boost solenoids. Plug the BCM module in to each being careful to keep the male/female pairs separate. They are not interchangeable. When plugging the connectors in to the solenoids ensure the pins are fully posted in to the connector. A loose pin here will result in stock like vehicle performance (full boost in one bank and low boost in the bank with the loose connection).
8. Put it all back together but don't refill the IC yet in case you made a mistake and need to take it apart again.
9. Reconnect battery and start the car a few times to ensure there are no fault codes coming up. Assuming those look OK top off the IC coolant fluid.

Since so many are running flash tunes now with no idea what is going on with their engines, plagued by misfires, etc, this will be a nice way to datalog and fine tune those setups.

Having boost mapped by gear will also improve launching traction, and the boost gauge in dash is also a nice feature. Not to mention active sound delete, LED max brightness, etc.

So actually no difference on the tuning side regarding owners of the bms stage 1, only logging feature right? So still tuning my tmap sensor and that's it? I thought there would be fuelling too.

Correct no fueling changes. That would require flex fuel wire connectors to the fuel rail which can be installed but are a pita to reach. On the plus side since there is so much CANbus data coming in now like engine speed, pedal position, AFR, timing in multiple cylinders, etc, the tuning itself can be more refined.

We can make it smoother and safer but peak boost can't be raised much above what was being run on the Stage1 as the wastegate duty cycle is limited. So to get power up we're going to have to figure out a way to get some level of boost solenoid control. That is what I'm working on now. But again the prospects are not great, as the solenoid connectors are difficult to reach.

We may conclude it's best to use the JB4 as a support tool for fine tuning and adding features to flash maps. The first order of business is to evaluate how well the currently released flash maps are in their boost control, fueling mapping and timing mapping.

I have seen other companies such as G-Power who control fuel too, but through a pin in the ECU not the rail itself.. They have control of the tmap, MAF and fuelpressure, check attached pictures:

[Terry @ BMS]

If you care to cut/solder a wire in the harness then that's fine for fuel pressure. On the test car we just run a PNP connector to the sensor itself. It's just hard to reach. So much so I would not expect the average consumer to bother with it. With meth flowing anyway it's not needed for OEM turbos. MAF is useless to intercept. We just read it via CANbus.

The good thing here is that you won't need as much adaption vs no control of the fuelpressure. I can do that, if you have some pictures and maybe a PNP connector, I bother doing that! No problem for me BMW mechanics will do that with ease I suppose.

I can email you if this is possible.

[Terry @ BMS]

Fuel trims are one of the loggable parameters in the JB4 so we'll be evaluating everything. We have a lot more possibilities now in what we implement. What we decide to do with all the new options is yet undetermined. Development continues.

[andym3100k]

Yes getting it asap, once able to limit boost to avoid wheel spin there is high chance that can get into the 10s!

[Terry @ BMS]

Working on BCM photos.

[lfelunden]

Nice work T!
Regarding the fuelling, that would be nice for us users who do not want to run meth.. Also, meth is so expensive here where I live (same story with racegas).

[Terry @ BMS]

Better reference photo for the CANbus and METH wires when doing the upgrade.

[lfelunden]

Terry, you should make a thread at m5post too! Not many are aware of these news!!
Please go for the fuel pressure

Lucky man.... G.

[Terry @ BMS]

I was able to access both boost solenoids by popping the coolant lines off the passenger side intercooler and rotating it out of the way a bit. It's about an hour job and fully plug and play. I figure its better than cutting wires going to the DME.

Also if someone finds their fuel trims maxing out and wants/needs to add in the fuel pressure connections that is their prerogative. It's easy enough to add the connectors to the JB harness and we'll support them. For those of us with meth or using pump gas, it's not really a factor.

[andym3100k]

T, good to see you really work on this car....all the way....

[lfelunden]

Nice! If you could do a write-up for the fuel guys, that would be great!

[speed808ix]

So the question is when can we order this

Will do. We're still in the early phases. We sent a few tuners out to start collecting some data but it may take a few weeks for us to finalize the connections being used and firmware.

I'm *really* excited about the boost solenoids. This opens up the tuning to seriously more power especially on meth.

Nice man, seriously can't wait. If you need any data collection (without meth) let me know, I can help you out (requires JB4 ).
Will be nice with the fuel pressure. Few weeks is fine, as long as you've turned your eyes to this engine, I'm sure you will hit records in no time.
