Use subject to terms and conditions posted at http://www.burgertuning.com/terms.html

THIS PART IS LEGAL FOR USE ONLY IN COMPETITION RACING VEHICLES AS DEFINED UNDER CALIFORNIA LAW, AND IS NOT LEGAL FOR USE IN ANY OTHER MOTOR VEHICLE. California law defines a "racing vehicle" as "a competition vehicle not used on public highways." (Calif. Health & Safety Code 39048) This part may only be used on competition racing vehicles operated exclusively on a closed course in conjunction with a sanctioned racing event. Competition-only motor vehicles may not be driven to a racing event on a public highway and must be transported on a trailer or other carrier. USE OF THIS PART IN ANY OTHER VEHICLE MAY SUBJECT YOU TO FINES AND PENALTIES FOR VIOLATION OF FEDERAL AND/OR STATE LAW, WILL VOID YOUR WARRANTY FROM BURGER MOTORSPORTS, INC, AND CAN VOID YOUR VEHICLE'S WARRANTY. It is your responsibility to comply with all applicable federal and state laws relating to use of this part, and Burger Motorsports, Inc hereby disclaims any liability resulting from the failure to use this part in compliance with all applicable federal and state laws.

Installation is the same as the n63 connecting to each TMAP sensor on the intercooler and running the OBDII cable under the dash. Additionally the MAF connectors (on the to of the engine) must be unplugged for the n63tu JB4 to function properly.

V2 systems now also include optional built in BCM connections which can be attached for those looking to push higher boost levels.


Dyno Testing:

3/17/17: New n63tu dyno record here! http://www.n54tech.com/forums/showpo...1&postcount=28
5/1/17: Broke the 600whp barrier! Yet another n63tu record: http://www.n54tech.com/forums/showpo...1&postcount=64

Firmware:

Note that older system shipped with a V1 EWG board while systems shipped after 2019 include a V2 PWG system. The V1 EWG board does not have BCM connections and will not operate with the V2 PWG firmware.

Map guide:

Map0: JB4 disabled
Map1: Additive map, up to 5psi requested over stock
Map2: Additive map, up to 6psi requested over stock
Map3: Absolute map, 18psi peak, BCM suggested
Map4: Stock with CANbus active for logging and in dash gauges
Map5: Absolute lower torque map ramping up to 20psi at redline, BCM required
Map6: User definable map generally used for diagnostics
Map7: Absolute map, 23psi peak, BCM + fuel control wires required
Map8: Progressive WMI map, boost varies based on meth flow and boost additive on the WMI page. BCM suggested.

Optional fuel control wires:

Not included with the JB4 system but can be added to V2 PWG boards for those looking to run higher boost levels or E85 mixtures. Also a bit of a DIY project. You'll need to identify your fuel pressure connectors at the end of the fuel rail, determine if they are "large" or "small" style, order 2x fuel pressure connectors from our website, and extend the wires on one as required to reach the fuel pressure connector. The JB4 pins for the connectors are posted in the photo here: N54Tech.com - International Turbo Racing Discussion - View Single Post - F Chassis N63TU JB4

How to update firmware:

For firmware updates if having issues we suggest you turn off WiFi, change upload timeout to 25, and set your phone next to JB4 box under the hood.

Looking forward to this! 2013 750li n63tu, I want in on this! I thought you all forgot about the TU

padrino 02-24-2017 06:50 AM

Looking forward to it! 2016 750xi here, love the potential this engine has for tuning

Pure Turbos 02-24-2017 11:52 AM

Sweet! Nice work! Huge gains per $ !

:clap:

Did you find any limitations on the top end? Turbos or HPFP or Octane?

m123 02-24-2017 12:03 PM

Great work

Terry @ BMS 02-24-2017 03:34 PM

I hope the trans holds! lol. If only we could reach that 2nd boost solenoid there is another 50hp at our fingertips. I guess worst case might be to make the BCM posi-tap installed somehow for the really hardcore guys.

the trans can hold torque more than the f10 m5

Is there a time frame when the JB4 will come out for the 550I?

Where exactly are those solenoids? If the "hardcore guys" are anything like me, they'd rather do some disassembly for access than use posi taps.

Terry @ BMS 03-03-2017 09:18 AM

We'll post more info on adding a BCM to the n63tu once we're further along in development.

535_BiTurbo 03-03-2017 03:33 PM

NICE GAINS! your N63 and N63tu baselines are very close 408/407hp and 456/466tq...
Once you added the JB4, Do you think your prototype intake played a major role in the huge power and tq spread vs the N63's dyno?

kokoN63TU 03-03-2017 05:52 PM

great news !!!!!
i have 2013 bmw 750i
stage 1 flash tune
8.0 sec 100-200 kmh (62-124 mile) race logic
cant wait to add jb4 to gain some power

Terry @ BMS 03-03-2017 05:58 PM

We're not yet sure to what degree the intake has added performance. We're waiting for the next revision and then will dyno it vs. stock. Unfortunately, it's the height of our busy season, and with so many projects under development, there is little time to go around. We'll get it done though.

kokoN63TU 03-03-2017 06:05 PM

Can wait
Good luck
Interesting what we can do with back and flash + jb4 on n63tu engine
Now I'm producing
499 whp on dyno mustang
And 78 kgm

Meth injections
30% e85
And some logs and tune with the jb4
I thing it will be a huge difference

Got a picture or graph?

kokoN63TU 03-03-2017 06:38 PM

Yes but it's on my phone not on my pc
And sorry but I don't know how to upload pics from my phone here/:

Mike_L 03-04-2017 07:17 PM

Hum..... gotta do some research on the 550/750 xDrive system. A 700hp+ 750LiX would be awesome. B7, S8 Plus and S65 killer.

EDIT: That was easy. All BMW cars, from the 1 series to the F02 B7, use the same ATC35 transfer case. The X5/X6 use the ATC45 (or ATC700 for the M's). So its the 8HP70Z, ATC35 combo. Should be pretty safe, up to the driveshaft at least.

BTW Terry, Did you ever find out about that 550 that was losing power with the DP? Its been a while, but I think it was cutting boost or something above 4000rpm? I'm going to assume this fixes that?

jandraos 03-06-2017 01:04 AM

Terry,

Will the BMS prototype intake system fit on the Straight N63 or non TU, if so when do you expect release date?

Maza454 03-17-2017 08:17 AM

I hope it will work for a 2014 X5 50I too.... and i am in the hardcore group, so ready to test and help with the development.

Was able to strap it down with the BCM installed and I'm very impressed with the factory turbo performance. Made a drama free 570whp on E35 fuel. Still no meth, no exhaust mods, etc.

The only drawback with the BCM is you need to cut an OEM wire to install it. It will likely remain an optional part of the n63tu JB4 system, but if you're looking for big gains, it made a huge difference. So much so that we are maxing out the factory 2.5bar TMAP sensors. Fortunately the JB4 can run 3.5bar TMAP sensors. We'll be swapping over soon. :)

Mike_L 03-17-2017 04:38 PM

Ooh..... cutting a wire kinda knocks out the casuals and the leases. There's no other possible way to do it? Maybe a harness extension that plugs in and has the necessary wire connected where it needs to go instead of straight through?

Terry @ BMS 03-17-2017 04:47 PM

Nope, cutting a DME wire is the only viable method. It will weed out the boys from the men. :) You can always reconnect it later to go back to stock as its not in a particularly visible spot.

You could always pull the contacts out of the connector housing and insert tap connections at the DME like this:

Attachment 60904

I think this is still only for hard-core guys since extracting the old contacts and inserting new ones into the connector housing takes a some intricate work (I built a custom tool to help with it) and if you're not delicate when extracting the contacts the housing could easily be damaged, but it does eliminate the need to cut wires.

kokoN63TU 03-18-2017 09:01 AM

Very impressive numbers
I will happy to see the results on the road on real time
100-200 time for example

Terry @ BMS 03-18-2017 10:01 AM

There is no easy way to remove the contacts from the DME connector. You could cut the wire and crimp on contacts to make a connection like about. It's just one wire we need to intercept.

turboalb 03-18-2017 01:32 PM

Nice numbers guys, needs a lsd now. Then try the 1/2 mile again

m123 03-19-2017 04:51 AM

Waiting so hard to order the jb4! Hope its available soon!

DrewBert 03-19-2017 09:51 AM

any pump gas numbers?

timberwolf 03-20-2017 11:10 AM

Wow great results! I would imagine Xdrive cars would grenade the transmission pretty fast.

Doubt it. The 8HP70Z they use is very similar to the 8HP75Z in the X5M and the upcoming M5. It can take plenty of power and traction.
