Default Missing Menu Option and startup roar gone? - 08-25-2021, 10:43 PM

Hi guys,

I have just installed a new RHD 2013 N55 Type B Jb4 in a 2012.5 135i N55 DCT RHD UC92.

When I go through the menu on the dash It only goes up to 14, not 15 So can someone please confirm which menu is missing?

I assume its the 2 step rev limiter and therefore referencing the menu option from there onwards is -1. e.g. gear 3 boost reduction is menu 14, gear 2 menu 13, until where rev was.

So I think I accidently changed duty cycle thinking that menu was the pedal input.

Also my MHD startup roar seems to have gone, is that just because the JB4 is controlling this now or should I try re-flashing it back on or something?

Thanks in advance.

Was the JB4 new, purchased directly from BMS, and the menus are calibrated for your car? Have you tried uploading to the latest firmware?

I think you missed one of my questions and that may be your issue. If not, post a video of what you're seeing.
