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. :)

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.

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

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.

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.

Time will tell!!

How'd the trims look at 19psi Terry

padrino 03-23-2017 06:14 PM

Really looking forward to it.. My dealer was trying to sell me on the Dinan tune until they realized Dinan doesn't have anything yet for the 2016 750

535_BiTurbo 03-24-2017 02:59 PM

timberwolf 03-27-2017 07:50 AM

I'd love to see this 550 run down an F10 M5!!
