its there in all ecu cars Stock cars
the limiter cuts of the engine in simple words just to protect it.
Whereas in the case of new cars .If the engine is cold The Limiter's limit comes around 4k when its actually not moderate enough for engine.Thats what i have seen in the new city myself.
Otherwise when the car has stopped and the temperature is half way less. Try it its going to head up to 6.5 rpm max then start cutting off
