So Ive been looking at videos about mustangs that have the launch control, some rev the engine but it sounds like it gets to lets say 3000 and bounce to 2600 on and on again,but on some other videos the rpm stays at a certain value but it sounds like it stays more in the selected value and sure sounds very agresive

Is it because some cut of fuel and other cut off spark?

 

sounds odd , I thought they are just a cylinder to hook to the front break lines , push a button pump the break & giver as soon as you let the button go your gone. I have a Hurst set up ready to go in.

 

Isint that a line lock?

 

line lock is launch control , I ran around looking for my line lock kit nobody knew what I was talking about , then they say oh you mean launch control .

 

I believe that 2 Step just holds the car at a given rpm so that you can dump the clutch and launch. It allows you to be more consistent and is popular on cars with large turbo since it allows them to build boost. I'm not sure what the 3 step is but I've also heard of it.

 

Line lock is in no way "launch control". The two step modules and such hold the engine at a set RPM under full throttle, then when the brake/button/clutch is released the limit is pulled and the engine can rev to redline.
