Looking more in depth, launch control holds the engines RPM at a set number allowing for the car to build power before the computer or operator disengages the clutch.

Aftermarket Launch Control •	Two-Step Rev Limiting Modern vehicles are increasingly becoming equipped with launch control features available straight from the factory. However, if a vehicle doesn’t come equipped with such features, then aftermarket forms of launch control can be purchased and installed. A common form of aftermarket launch control is commonly known as two-step rev limiting. A two-step rev limiter is a module that regulates the engines rpm’s for a controlled launch and optimal power settings. Suggested in the name, two step limiting confines rpms at two sperate points. The first point is programmed to limit the revolutions to a desirable launch range and the second point is limited to protect the engine from over revving. The limiting itself is controlled through the modulator by regulating the fuel and ignition. Once the desired revolutions are met the two-step system will adjust these parameters allowing for power production to cease until released. Its important to note that two step rev limitation is only a viable option with a manual transmission car. Launch control for an automatic transmission car requires a different set up. Reasons for use Launch control was originally intended to give cars the ability to accelerate as fast as possible regarding optimal engine conditions from a stop. However, car communities around the United States have begun to organize events surrounded around the byproduct of launch control systems, this byproduct is usually called a backfire. Using aftermarket launch control systems allows for drivers to manipulate the fuel and ignition settings. To create a backfire, the ignition settings are turned down allowing for a build up of excess fuel which creates a larger combustion producing loud bangs and pops from the exhaust. In some instances the launch control systems are modified to produce large flames that also expel from the exhaust pipe. Competitions are held in car communities based on achieving the loudest backfire or producing the largest flame. History From being a feature that was predominately seen only in race cars, launch control is now featured in almost all modern consumer car brands. Brands such as BMW, Dodge, and Mercedes all have implemented a launch feature in select models of their vehicles.
