Having my JB4 Stage 1 installed tomorrow while on the Dyno. Will do 2 baseline runs without it then followed by 2 runs with the JB4 Stage 1 installed. Expecting the numbers showed in the BMS site...

Dyno sheet will be posted up afterwards for the world to see.

Dyno Results

Finally was able to get the car on the dyno this morning. The baseline was performed with the aFe Intake installed as I didn't want to waste time/money putting the stock on and off. The car delivered very well with just the intake alone. Looks like the torque numbers were higher than expected when compared to the another. My tuner said the 295.57 HP and 327.08 Torque is the highest stock numbers he has seen on his dyno for any stock N55 motor including a 1M that he dyno'd. That tells me we are getting a bit more power than BMW is letting on

With the JB4 Stage 1 installed we see gains in both HP and Torque, but to be honest not what I was expecting from the BMS suggested gains posted on the website. The best was 323.15 HP and 365.67 Torque. A peak gain of +27.58 HP and +38.55 Torque. That said, for less than $400 and two easy connections to insert it still is a good deal for this car. I hope the JB4 Stage 2 running Map 1 puts out better number with the added controls.

Those are great gains for the Stage1! And down the road when you're ready for more power you can upgrade it to the JB4 Stage2.

The F30 and M235 is the same version of the JB4. Both Harness B. We recently added the M235 as a separate option to make it easier ordering.

I installed the JB3 on my N54 and it was a bit of a bitch - I have heard the N55 is worse - what have been people's experiences so far?

The N55 JB4 is simpler I think then the JB3 was on the N54.

What's the difference between stage 1, JB4, and stage 2?

Sorry for the newbie question, just confused from the BMS website.

Shoot me a PM..

The EWG is for cars with the Electronic Wastegate. So all 2014+ cars. Its allows you to take full advantage of the JB4.
