JB4 BETA for E70/E71 2010-2013 S63 X5M & X6M
 

**** 6/17/17 Update: We've decided due to higher than expected support requirements (the S63 motor is a bit of a headache) and low sales volume no longer to officially support the S63 JB4 system. We will continue to offer the BMS Stage1 for the S63, it requires the N63/S63 Harness A model.

For those who want to DIY an S63 JB4 kit you are welcome to do that just realize no BMS support will be provided. The required hardware is same as the N63 JB4 TypeA and then you must also load the S63 firmware is at the bottom of this post. Directions are provided in this post for installation and the wheel control menu works the same as the N55 E series JB4. Note CANbus must be installed in the ECU box using posi-taps as shown below for it to operate properly. BCM and fuel wire support is no longer provided for the N63 and no wires should be installed to the ECU.

VBOX testing:

1/4 mile 12.0@118.9mph, 3.7s 0-60mph on the E30 map.

Map Guide:

Map 0: JB4 Fully Disabled
Map 1: Additive map targeting around 4psi over stock. BCM optional.
Map 2: Absolute target map targeting 15psi peak. BCM required.
Map 3: Absolute target E30 map targeting 19psi peak. BCM required.
Map 4: Stock tuning with CANbus active for logging and gauges
Map 5: Under development
Map 6: User adjustable map. Values below 10psi make the map an additive map while values over 10psi make the map an absolute target map.
Map 7: Progressive methanol map under development.

After a few days of hard work I have the guys of the system working. Installation is very similar to the N63 in that you connect to the TMAP sensors using the Stage1 harness, then plug in extra wires for CANbus, fuel control, and the BCM. The fuel control, BCM, and CANbus wires connect inside the DME box. See the N63 JB4 installation video for basic directions on how that looks.

The tricky part on the X70 is reaching the DME and getting its cover off. You remove the panel and HVAC filter, pop out this piece, and then the DME cover takes a bit of patience to unlock.

Inside the DME area the MSD85 looks just like the N63 DME. You pop off the connectors and pop in the JB4 wires using OEM contacts joining 2 pairs for fuel control and 2 pairs for the boost control. Finally CANbus connects using removable posi-taps.

If upgrading from a Stage1 kit then you'll first need to insert the new wires in to the Stage1 harness. Note that is the same as the N63 Stage1->JB4 document referenced below.

Install directions for s63 JB4:

1) Install the TMAP connectors and control box per the s63 Stage1 installation guide: http://www.burgertuning.com/instruct...e1_install.pdf
2) The S63 does not use OBDII CANbus and instead connects directly to the CANbus in the DME area using removable posi-taps. Using the included posi-taps attach the green/brown CANbus wires to the blue/red wire pair inside the DME box as shown.
3) The DME specific fuel and BCM wires attach to the DME just like the N63 system referenced here: http://www.n54tech.com/forums/showpo...92&postcount=3

After connection the JB4 box is placed as shown.

Finally pop back on the factory covers. I left the BMS DATA cable sticking out for quick access. But the system is also fully compatible with JB4 Mobile for iPhone or Android use.

The system has full E series wheel controls including map switching, in dash gauges for boost, timing, AFR, etc, adjustable shift light, etc. We suggest turning on boost on fuel, setting menu 2 to 1. Menu3 is the user adjustable shift light.

#1, I'm interested Terry. I'll spread the word. I like to thank Terry for taking the time and moving forward on the s63 platform. I look forward to n54tech and his support.

If it was available when I had the X5M, I'd have bought it in a second. Problem now is, the prices have dropped so much on them that ordinary (non-BMW type) shlubs are buying them. Who knows if they can afford another grand for a JB4?

The owner of this one told flash maps are available but priced around $2000+ or more. Hopefully we find a demand for the S63 JB4 as I've already wasted a few days on development. ;)

Was able to do a few VBOX runs on our private track tonight.

Test car is a 2013 X6M running 93 octane and apparently ***.

Stock:

Great work... every JB4 in the market makes for more JB4 development :)

Terry let me know if you need a test x5m, east coast .I have 2 1/4 mile tracks close by and have a couple of stock runs already.also other daily drivers besides the x5m.

Al

Those numbers are almost identical to what mine was running with the Stage 1. Crank up the boost and put on *** and it'll drop to about 3.6 to 60 and 11.8-11.9 in the quarter.

I've been bugging you for this for months, so naturally I'm in!!!! We recently added a new vehicle to the family, an 08 535xiT, which the GF is tired of being walked by my X5M. Having NEVER been a car person until owning her first BMW, she is fully onboard for modding, so I've already got your DCI, oil catch can and JB4 sitting in My Cart...make both our day!

I already bought an Aquamist HFS-4 kit for the X5M since it's claimed to be the most advanced system out there to run on vehicles without appropriate tuning, but ultimately I'd love to be able to run JB4, BCM and integrate your meth controller to run my kit so I'm not spraying meth blindly.

On the X5M have a photo of the dash? For meth you'd use an FSB and the JB4 can control it. On the hardware use what you'd like but likely our kit is the best way to go there.

What do you mean photo of the dash? It should be exactly the same as the X6M you've got at your shop.

I wanted to buy your suite of stuff as a meth controller, but I've already got a stage 2 flash tune created by Halim, which I'm assuming means it'd be going backwards to run a stage 1 piggyback just for the sake of controlling meth. I don't know how all your devices need to speak to each other, if one is needed to make the other work, etc but I assumed no matter what I'd need to start with your stage 1 for tuning, then add your meth controller, then add JB4, then last but not least the BCM. Up to this point the JB4 and BCM haven't been available to the E7* X vehicles, so I've settled for my stage 2 flash tune. If I'm correct in my assumption that I can flash back to stock, run your stage 1, JB4 and BCM, which will allow me to run circles around any stage 2 tune out there, then I'm absolutely in...meth control is just an added bonus.

Seeing what numbers the M5/6 is getting, granted it's always going to have a higher output, but it'd be nice if the E7* could finally start doing everything you're already doing for the M5/6.

I know it should be. I wanted to verify it was.

On the tune you can keep the flash in place and the JB4 will just work on top of that. In terms of performance gains that would depend on what the flash does and how much is left within the factory parts being used. I have not seen any S63 flashed datalogs. So first order of business once a JB4 is on will be some datalogs.

The good news is the in dash controls and logging will be better than the s63tu JB4. :)

At this point I'm running Halim's stage 2 flash tune with coding to disable the CEL for *** less down pipes. Just so I'm clear at what I need to buy and/or how all these things go together.

- I can leave on the flash tune, then install your JB4 and BCM, send logs and see where it takes us?
- In order to run your meth controller, I need to install your stage 1 piggyback, but do I need to flash back to stock or can your stage 1 piggyback and my stage 2 flash work together?

I haven't installed the HFS-4 yet, so I'd like to know if I should resell it or keep it in an attempt to do everything efficiently while still getting the most benefit since the JB4 can now officially be used..if you get enough interest.

I'm very interested. I would ideally like to use this to get a little more boost and timing on top of my tune with meth if I could. I have a '13 x5m and have had the jb4 on my 335 and the wife's 135 for a couple years now and love them. I know you have to get your margins, but the tunes on the x5m have come down recently. I think they are about 1k at AAtuning and a few other places, with sales prices being lower. I had mine done for less.

Alright... I'm in :)

Love seeing that boost holding to redline! Should make for some awesome ass hauling

The system is setup like the N63. There is the JB4 system with CANbus and fuel control wires, that is $799. Then the BCM is a $150 add on.

If you already have a flash map then I'd start with just the JB4 system and evaluate it. You probably also don't need to install the fuel wires as presumably the flash already has been scaled up on fueling. We'll be able to tell from the initial logs, though.

For the JB4 to control meth you need an FSB system which can connect to any pump/solenoid out there. In the case of your AM kit it would replace the AM controller. Alternatively you could install all the AM stuff and as long as it has a flow sensor just route a 0-5v flow reading in to the JB4. Installing those AM controllers is a huge pita though so have fun with that. ;) The FSB is much easier to install.

Makes sense. No reason a flash tune should be more than $500 given how easy they are to load on the platform.

The JB4 itself will be $799. Once someone with a flash tune installs one we can evaluate the tuning potential left.

For sake of ease of installation, I'd rather be all or nothing, so I'd rather sell the HFS-4 setup and do the full BMS suite since it's getting great results for the M5. Since you've mentioned the JB4 is the same as the N63, I didn't know the N63 could run JB4, so are you saying the JB4 is ready to go now for the S63 or do you still need your 20 interested people before you produce more?

Flash tunes are still $800-$2500 depending on seller, which is funny since it's been discussed that all those tunes are nothing more than a $250 BR base tune that's then tweaked a little more by each reseller, marked up and relabeled as "our _______ custom tune is the best in the industry". Yes, flashing with the provided cable takes about 10 min. I remember that part of the thing about using a piggyback is it clears CEL lights of ALL codes vs a tune can shutoff specific items like down pipes. Is that still the case?

I'm flash tuned so I'm all for buying one once it's ready.

The JB4 clears passive faults if enabled but real faults continue to show a light in dash.

It's not ready for sale yet for the S63 but I've done most of the "work" of it. Now I just need to wrap up the software, get some base maps well tested, and then we can open up BETA.

At the moment I get a code for boost plausibility, which doesn't kick a light and I'm told is simply a sensor I need to replace. The down pipes do kick a CEL though, so I'm guessing that's what you'd consider a real code and the light would remain on if I'd flashed back to stock while using the JB4.

JB4 is mostly just a logging device and doesn't add any power by itself, correct? If I can use the JB4, that means I can also use the BCM or am I getting ahead of myself?

Jb4 is absolutely for power, everything else it does are the bells and whistles
