228i JB4 & Catless Downpipe

RourePR · 03-10-2016, 07:45 AM

Just installed a Catless DP on my 228i(N20) 2016. The car sounds loud at a cold start

20-30 seconds after, the sound is normal. I have the JB4 Stage 2 on map2 with 93 octane. Sometimes the car like stops accelerating and then keeps running. A friend with a 135i FBO told me that the JB4 has a "Boost Safety" if it passes the boost limit, the JB4 itself is going to do that. He told me to get the USB Data Cable and adjust the "Boost Safety" in a laptop or buying the JB4 Bluetooth kit and do it from my phone.

Nice...

Are you running the stock exhaust? Mind uploading a video of cold start, and some revs?

As for the JB4, i thought the boost was set at a specific level... how would it make the engine boost more in order to make it go into safety mode?

I still havent ordered my JB4 yet, but i plan on doing so soon.
