How to properly Drive / Race X5M?
Ok it sounds silly but really... what would be the proper way?
Giving the fact that i have M2 setup as level 3 shifting, sport everything and DSC off. -When launching, how many second do you have to alter the launch RPM and is it only by pushing up and down the cruise control button? -After you launch, do you shift gears or does the car do the shifting? -When you shift gears (with the M HUD Visible) do you shift where it gets to the end of the yellow dash or way up to the red Dash? (the reason i ask is because once i get to the second red dash and shift i feel that the turbos are lagging. -Can you switch to D mode after you launch while the car is in 1st gear? What would be your preferred rpm, gear and speed if you are racing from a roll? Last edited by LBBX5M; 06-13-2016 at 07:30 PM.. Reason: spelling |

You can not alter launch rpm.
Your choice auto or manual. Whichever floats your boat. You'll have to experiment when to pull the lever to get the proper rpm. Looking at the dyno sheets 6500ish is close. I wouldn't try to shift to D at wot. Have it where you want it before you launch. Good luck ! |

My $.02 is to let the vehicle do the shifting if you're running from a dead stop. It's hard to beat the launch control and the perfect shifts each time, especially with so many gears.
When I punch it from my current speed (I'm in M2 with the same settings you're using), I pull back on the downshift paddle several times. The car will downshift to the lowest possible gear, ensuring you're deep in the power band. It obviously won't allow you to shift to a gear which is too low for your speed. Coming out of an E70 X5M, the F85 has a different transmission feel with the 8-speed over the 6. It's harder to gauge the most powerful gear using the old-fashioned methods of engine sound or speed. |

I have found that you have to "teach" the X5 that you are wanting to race.
1. In automatic, with vehicle at running temperature and from a dead stop, the X5 did not go all the way to red line under WOT. 2. Going to manual shift, and after two hard launches, I usually shift when the display is high yellow. Waiting to get into the red sometimes will engage the vehicles protection to over-rev. 3. The next time I ran WOT in automatic and the vehicle is now shifting at red line. |

I wish if there was a video of an X5M F85 launching and someone to show how to shift it properly... I am sure it will be a hit on YouTube. |

yea, i'm fairly sure you can't go over redline as there is a limiter in place (it's not the turbos lagging that you're feeling - there's nil lag at RPMs that high). I know I've hit it. I know some of the tunes can raise the limiter slightly, but I'm pretty sure the limiter is in place to keep one of us from accidentally blowing the car up...

do you think I can get boost, rpm, speed reading and maybe we can tell if there is a lag? because I am sure the feeling I am getting feels like a lag in the turbo preformance like a second for it to get back at full boost

if you're talking about what you're feeling at redline it is the limiter kicking in and cutting power so you don't go over redline and potentially damage the engine. But at lower RPMs, since the car is a turbo, there is some lag (even though the lag may be minimized, etc.). Once the car hits the limiter, when you shift it does take a second or so to allow you to spool the engine (and turbos) back up if that's what you mean. HTH!

push down the DSC traction for several second until you see a sign that traction is off switch all your modes to sport plus gear shifting level (volume) at 3 switch your gear from D to manual and all the way ti first gear Push in your breaks with your left foot step on the gas pedal (not mildly otherwise you will not engage launch control) about 1/3 to 1/2 the way in you will see the racing flag appear on your dash Let go of the breaks and shift accordingly |

I can never get launch control to engage. Once you do, doesn't it do the shifting for you? I thought that was one of the purposes of launch control. In my 2013 X5M, once I engaged launch control, all I had to do was take my foot off the brake and the car did all of the shifting.

I went to the track last night. My best launches were just using the brake and gas to tighten up the drivetrain and have the vehicle squat.
My best run was without shifting manually. I did shift manually for my second best run, but used the tachometer on the dash instead of the HUD. The tachometer was nice and gradual and it gave me more time to react to shifting. |

I Tried Both Auto + Manual on the Drag Race I started with the runs at 12.1 i think when my Car was stock and now Holding Record of 11.6 with a Tune I recommend using Auto and Modes on Sport Plus except the Suspension i prefer it on Comfort than Manual from a Dig but if u Are Racing from a Roll Race in this situation GO Manual & it depends from which Gears u are going and u should shift before redline to hold its power + regarding the Lagging u feel its normal with the x5m ^_^
Regarding the launch control that video was posted from a member in the fourm Hope it helps Last edited by shark- bite; 06-19-2016 at 12:18 AM.. Reason: spelling mistakes |

Notice the 1-2 shift happened way before red line. 5200.
My best run is preload with gas and brake at same time, get rpm to 2000. Then launch. Before I get to the track, I manually shift hard to red line to get the vehicle, "in the mood". My first run the truck in automatic will usually go to red line and shift. The better I get at manually shifting using the tach, the more I will resort to that. I find the 1-2 shift in automatic is very inconsistent. I have tried different "resting" periods between runs. Lift the hood, cool it down, or I find leaving the vehicle running it will cool itself. Haven't found my the best choice on that. |

did you have to use the actual gear nob to switch between gears or does it shift by it self? knowing that in order to activate launch control you have to move from D to Manual and you have to make sure that its set on 1st gear |

The U.S. version of the launch control launches at a lower RPM compared to Euro. Not worth using LC in the U.S.
Instead, build boost yourself. Vehicle in D, one foot on the brake, one foot on the gas, build boost to 3k RPM, then release brake. This also reduces stress of the your drivetain.

The U.S. version doesn't have this option. I doubt it.
