    I've been trying out launch control lately. First few times I used it with traction off at 3,000 rpm and had the throttle all the way down and she just hooked and took off but ever since then it doesn't hook it just spins out. I am trying this on the street I haven't been on the drag strip yet. Also if I punch it on first gear at about 4K rpm it won't spin but when I shift to 2nd gear it will spin out. How the hell do I not spin out?

    I haven't gotten to play with it too much, the couple times I tried it real quick, the car just spun as well. But, to your comment about doing it on the street, that is whatit was for. Our launch control was designed more for use on the street then on a track. On a track it can actually affect your times

    I can't get mine to work too well either. It almost always spins the tires so much that it turns itself off. It says "Launch Control Cancelled".

    That hasn't happened to me yet. Are you on the stock tires? I have the 555's on mine and it still spins out really bad

    I've tried it on the factory summer tires and 555's. Was obviously better with the DR's, but it still happened.

    Try 1800 rpm, start in 2nd gear, manual shifting

    launch control is tricky. you need everything set right and the steering wheel STRAIGHT. any amount of left or right will cancel it out

    Launch control on these cars is a joke really.

    2nd gear roll to mash FTW. Unless you have an upgraded DS - then mash the fugger.

    I didn't think starting in 2nd gear was necessary when using launch control. Maybe that's what I've been doing wrong.

    The trick (at least in the autos) is that the car has to detect a certain amount of pressure on the brake pedal. I can tell you it is more pressure than what you'd expect. I have a video of the process on here some where. Just search launch control.

    We played with the launch control early in testing as it was supose to drop some of the trans TQ management, but it really never worked right, to this day I'm not sure what the engineers in visioned this would be used for,LOL

    I tried it at 3500 rpm and it hooked and took off. Tried again at 3000 rpm and just spun out lol

    I thought the launch control was really intended for a car with Slicks or DR... not a street tire. Trying it with the stock Perelli's on the street... it just blows them off like a Funny Car doing a burnout. I haven't played with it much (Yet) so I can't pass judgement on if it is effective.Just curious... you guys racing your cats, what is your launch technique?

    I think they must've had a summer intern design their launch control. In other high power cars with proper launch control, like a 911 Turbo S, once it's engaged you just release the brake and the car manages power to keep the tires *right* on the edge of adhesion -- basically exactly what ABS does, only under power instead of braking. So the norm in a car like that is perfect launches time after time. It boggles my mind that Dodge's idea of launch control is just a rev limiter. It's not like this is a cutting edge concept; other cars have had this type of advanced launch control for years.
