commonly known as two-step rev limiting. A two-step rev limiter is a module that regulates the engines rpms for a controlled launch and optimal power settings. 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 aftermarket two step rev limitation is only a viable option with a manual transmission. Launch control for an automatic transmission car requires a different set up.

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.

engines. Due to the nature of how a turbocharger works, you cannot ensure that you have 100 percent of the engine's torque at a moment's notice. With a launch control system, you can ensure that the turbocharger receives enough exhaust pressure to maintain boost pressure. You can further amplify this

allowed the data to be sent by radio between the pits and the car. Increasing the use of electronics on the car allowed engineers to modify the settings of certain parameters whilst it was on the track, which is called bi-directional telemetry.
