I need serious help installing my JB4

LiLpenut · 06-03-2021, 09:10 PM

I have an ewg n55 (2015 435i xdrive f32) and for the life of me I cannot get to the ewg sensor to connect the jb4 to it. I know the ewg connection isn't necessary, but since I'm FBO I need it to run map 5. The ewg connection I legit right behind a hose and I cannot get to it, I have no idea what to do. The attachment is a photo of the sensor, it has to be the right one since it literally right next to the turbo. If anyone can help me out I'll cashapp, Venmo, or pay pal them $10 I swear to god.

Throw it out and get a proper flash tune.

Get BootMod3 or MHD you won't have to worry about wiring things up like the JB4

To set your mind at ease, there is nothing wrong with running a JB4. I have been running a jb4 with a backend flash for 3 years and have been very pleased with it.

It has some capabilities that a flash only tune does not, but there are always tradeoffs.

1 as you have seen is the ewg connection. If you have a large hand it will be a challenge to disconnect and then connect the jb4. It's a tight space and an awkward angle. Just be patient you'll get it.

I found this video helpful when installing mine.

I didn't use a fork. I ended up using a 45 degree pick tool and an extra long pair of needle nose pliers.

BMW loves to make these tight and awkward spaces. Don't even get me started on installing an upgraded diverter valve. 4 hours just removing and replacing a single screw.
