Seperate , it's an add on

The JB4 comes with the option, but I believe you have to fit a "DIY circuit"?

Ive watched a few 335i 2 step limiter videos on youtube. Most of the cars piss out heaps of black smoke. Dosnt look to healthy for the car. What are your thoughts?

Yep even Terry from Burger Motorsports posted a thread and said they don't offer it as a kit because they can't guarantee how safe it is for your car.

They also stated that if you don't have carless down pipes, the excess fuel that the 2 step dumps will kill your catalytic converters straight up.

I guess it's up to whatever you want to do. Do you want to shoot flames and leave big stripes?

Not sure about now. But back then I bought it , it was like $30 extra for it.
I installed my jb4 and realised I didn't jnstall the 2step. So it's just sitting in my trunk lol

And yeh YouTube that.

It's sold seperately.

Plug it in then activate it on the JB4 through the USB cable.

It's useful for:
a) drags (assuming you have enough grip)
b) shooting flames (exhaust permitting)

No Launch control but you can reduce boost in 1st and 2nd gear. Very useful for launching off the line.

Reminds me of bee-R rev limiter for nissan vehicles.

A friend blew his turbo when shooting flames doing this lol!
