Bc button jb4

Hello all,

So I recently purchased the jb4 piggy for my n55 335i. Everything works great but the bc in dash. To go over some things I have done: made sure obdII was connected correctly, f10 comp mode enabled. ObdII bc button is not disabled. Updated to latest firmware. Anything I’m missing here?

F10 comp mode? Does logging work?

Hi Steve.

F10 comp mode is enabled but unable to do any logging as well

Hi Steve

So I'm new with jb4 but yes I was able to log and take some pulls from 3rd gear 2500rpm

You're not driving an F10 based on your description though. ;)
