435i JB4 and Launch Control

StasF32 · 03-28-2016, 08:42 PM

Hey guys,

I was trying to do a 0-60 and I couldn't get anything lower than 5sec. I've installed JB4 and on map5 with 20% E85 mix I get no traction with launch control. I think I only get traction at 3rd gear. What is the best way to get do 0-60 without turning jb4 off? Also, I'm using the M Laptimer app that connects to ConnectedDrive and I'm not sure how accurate that is.

Thanks in advance

What RPM are you launching from? Anything above 1500-1800 would just keep slipping. When you get in launch control and the rpm reaches the peak.. Flick the knob on the left side wheel to lower rpm. From what I remember it always starts high

I didn't know you could do that. I think it was around 2500. Is this the knob you are talking about?

I thought only the M's were adjustable.

Try the boost limiting feature since you are overpowering the tires.
