Inconsistent Launch Control w/ F90 Comp
Has anyone experienced inconsistent launch control? I can’t get my stock F90 Comp to launch consistently for the life of me. Always bogs and short shifts leaving me with not so great 0-60s w/ my Draggy. I thought it was my vehicle, then I watched this:

Maybe it's a conspiracy!! BMW purposely did this in order to make sure the M8 would have better times. 😆
The same thing happened to me when I did my first LC. It's far too common in order for it to be driver error. Software needs to address this. |

I doubt BMW will address this. I wonder if this is something BM3 can address via a tune.

i had issues with LC when i first got my car and it came down to tire type, pressure and temp. the tires have to be up to temp for this to work. i see that you are in NJ and I am in PA.... long story short you have to switch to all season tires to use LC in the winter time. I use Michelin AS 3+ 285 all around and they work great. 30-32psi of air pressure and have to drive on them for 5-10 min, aggressive accel from rolling start helps getting them up to temp... i usually do this in 2WD mode.

my 60-130 is never good from a stop because i'm usually spinning at 60. launch basically hooks then spins on 1-2 shift then spins on 2-3 shift again. DA is good but the car doesn't seem to gain anything past a certain point. I did 6.0 60-130 in -1200 DA and did 6.1 in -2500 DA and 6.1 in +400 DA. It's almost like it compensates by targeting load.

I am also having inconsistent times with my launch control. On my 93 tune, best I can get is a 2.9 0-60.
On E40 Utku tune the best I can get is a 2.79. This is also with xHP stage 3 TCU tune and line pressure bump. I can only get 2.5/2.6 in drag mode when I launch the car. I always make sure the tires are warm and I launch just a moment aftet launch control is ready. Should I let it build more boost?
