What is the rev limit?
Unlike the launch control, the rev limit is a modification reserved for diesel vehicles that do not have the possibility to interrupt the current ignition (because devoid of spark plugs), by cutting off abruptly the injection of diesel, causing a sudden return of the laps engine and a particular noise, much to rename this change "rev limit".
How to enable the rev limit?
The rev limit is activated through the remapping of the engine control unit. This change does not increase the performance of the vehicle, however, it is high demand because it has a choreographic effect considerable, especially used during the demonstrations or car meetings.
