How exactly would it be useless? Our stock ones max out at 20 and that means I can’t go up in boost. I’m already hitting 17-20psi depending on the air temp outside so once I put my ********* on and 5 gallons of e85 yes it will definitely help me get beyond the point of throwing codes or whatever difficulties you guys go through. I’m also doing a tune on top of the jb4 so I will be doing a setup that holds a constant 24psi

I don’t know what cheap chinese TMAPs you’re running but I presently go up to 25psi on a heatsync stage 2 tune without issues.

[AzM750]

Just an FYI for people like me who were under the impression we needed 3.5 bar tmaps to go beyond 20psi. i have a vivid racing stage 2 flash with the jb4 along with VRSF ************ *********s ARM cold air intake N63intakes oil cooler valve ngk 2 step colder plugs this is on a n63 NON TU...on map 0 I’m running 17psi map 1 22-23 and map 2 23-24psi...so no need to add these unless you are turbo swapped

[Terry @ BMS]

You absolutely need 3.5bar sensors to safely run over 20psi. Otherwise, you're just asking to smoke your motor due to out of control boost.

[AzM750]

Should I be seeing boost spikes and huge variations? It seems to hold steady and the logs look good lol...guess I’ll be ordering the 3.5 bar tonight based off your response lol

[Terry @ BMS]

Post the log if you want tuning advice on it.

Do you have an ECU flash also?

[Wht550Jersey]

Posted a log for you . Thanks

Can you guys recommend some back end tunes for the n63? Thanks

Looks normal to me for map2!

[Newn63]

Terry at wot around 120+mph I always get a drivetrain malfunction this has been happening since I got my jb4 I just haven’t had time to address the issue could you please look at my tune 2 log and give me an idea of what I have to do to fix this issue? Thank you

Hello
I have a 2015 X5 xDrive50i with the n63tu and thinking about getting JB4

What type connector will i need?

Does it still having steering wheel controls like older versions? or will i just have to use the app?

[Yo_Holle]

Do I go from the pics on this page for choosing the connectors?
https://burgertuning.com/collections...cts/n63-stage1

Also for the BCM connections do I purchase a BCM or is that made to the car?

[Alexe70]

Terry can I get some help. I have downloaded new firmware for my ,13 x5 50i. But nothing on app works but the boost gauge. And when in map 1 or 2 boost doesn't get over 9 psi and runs sluggish. Is something wrong with my jb4? Advice?

[BMW750i/\/\]

quick question... i have a 2011 BMW 750i M sport with down ***** , cold air intake and jb4 and i just got the 3.5 tmap sensors and adapters but i installed them and i got the check engine light, so my question is do I have to change anything in the JB4 ??

[Mike_L]

Yes. There’s a setting for TMAP. 0 is stock, 1 is 3.5 BAR and 2 is 4 BAR.

[BMW750i/\/\]

thanks Mike_L

ohh one more ? ... do I need to change the boost level from 20 psi or does the JB4 do that automatically?

What map are you going to run map 6? I’m pretty experienced with this ECU and non tu setup. If you are looking to put in some work on the streets you will want to get a real flash from heatsync-performance euro, along with the jb4 stacked. Without getting into detail too much the jb4 is simply better off left in map 2 until then. I ran 23k miles on a super aggressive tune in a 2011 750i and ran a personal best on 11.89 and a consistent 11.95-12.00 any day of the week at any red light on dragy. But there are plenty of customers who simply got some stage 1 flash or some jb4 and ********* and have blown engines. A remap of this engine from a legit place will ensure you lay the smack down and it’s lasts. I believe I had the fastest 7 series non tu RWD car in existence you can always text me if you got questions 346-219-3863 as there is way more to this and I could help you way more in depth… I’m

[AzM750]

^^^to my above comment I am not a tuner I am simply an experienced owner and my own mechanic so I’m not claiming **** besides that lol don’t send me logs lol

Not clear what you're asking but the boost safety setting should be set 2-3psi above the highest intended boost target. So it only trips the safety if boost is going higher than you expect.

Any help would be appreciated. I have a 2011 550i 6spd manual.

BMW reman engine with 9k miles.

New in last 1500 miles OE NGK plugs, Bosch coils, air filters.

Only mods to the car are Meisterschaft exhaust with x Pipe and BMS throttle tuner.

The car had a drivetrain malfunction at the end of this log (5th gear).

I did have a code 102302 MAF air mass too high

I do have 2 step colder plugs, but haven't installed yet.

Thanks!
