M4 launch control not working?
Since a while i used the launch control again on the m4, but it seemed to not work as it supposed to be anymore, as it did in the past.
Left foot on the brake and throttle fully pressed, after that it said “launch control activated” on the dashboard with the checkered flag. But when releasing the brake it only gave me wheelspin so much i just kept standing still spinning. Also, just before releasing the brake i tried lowering the revs (from the standard 3000rpm during launch control) with the left tumbler on the steering wheel, but that didnt work either. Anyone an idea whats the matter here? |

Tires? If PSS they suck, get stickier tires.

Yeah it's hard to get it to work, I kept trying and when I finally got it to work. I had too much wheel spin and I am on PS4S.
First time using my Bmw F80 M3 Launch Control

It worked pretty good the previous times, same tires still. Also not able to adjust the revs is also peculiar, worked before... |

Any codes stored? Might need to be reset but that's weird. Even with no codes, I used to reset ECU on my S4 when weird crap would happen and then it will work again, electronics lol.
