pour les connaisseurs de bms jb4

et pour les troubles des n54 je te conseil BMG performance a Laval!!

sur la map 1, quand tu lâche le throttle dans les 2500à4000 tour à peu près, est-ce que le RPM hang haut ?
 
I had a similar issue in the past. Make sure your firmware is the right one and if not , you need to update it.
 
mon x3 2013 avec n55

map 0 je rentre haut 13 sur 1/4 a 98 mph

map 7 , 12.66 a 107mph

oui le jb4 marche tres bien avec n55.

t'as un probleme quelque part...
 
I have the JB4 on my 2018 Q50 TT. I was running map 6 fir a while but switched to map2 and yeah... HUGE difference. Check the logs in your jb4 cell app, you'll see what boost targets your hitting, etc...
 
Running a JB4 in the S6 and with Map 6 dialed in thanks to George @ BMS.... all I have to say is WOW

+9psi peak and +5-6psi taper to redline
 
JB4 on my Mini Map 6 with supporting mods. It surprises many people. My wife LOVES it as well. Updated firmware and according to Draggy it's high 13s all day, it feels a bit faster though
