How does the second stage of the rev limiter work?
How does the second stage of the rev limiter work?
The second stage of the rev limiter comes into operation at the maximum allowable engine speed for that application. This is more commonly known as the “Red Line”, which can also be set by the user, or programmed into the engine management system to prevent damage to the engine. How does a rev limiter work?
Are there different types of rev limiters in Australia?
On most of the vehicles the average Australian technician will see, there is only one rev limiter- the one that prevents the engine from revving beyond the maximum allowable engine speed. These can come in one of two “flavours”, a “soft cut” limiter, or a “hard cut” limiter.
What causes wheel spin on two step rev limiter?
A common complaint about aftermarket two-step rev limiting systems is that excessive wheel spin occurs when the first stage rev limiter deactivates. The remedy is relatively simple; since the VSS (Vehicle Speed Sensor) is recalibrated during the initial setup, the initial setting may be too low.
How does a speed limiter in a car work?
Those kinds of top speeds are out of the reach of nearly all cars on the road anyway, thanks to a device called a speed limiter, which also sometimes called a “governor.” Like many functions on modern, fuel-injected cars, speed limiters operate through electronic sensors and the engine computer.

Can a rev limiter keep engine RPM below the redline?
In the case of “neutral” or shifting up too late, a rev limiter can easily keep engine RPM below the redline. If a manual transmission is shifted down too early, the speed of the vehicle will drive the engine over the redline. In this case, a rev limiter will cut engine power but it cannot prevent the engine’s RPM from going beyond the redline.
What’s the difference between hard and soft rev limiters?
You’ve probably heard of ‘hard’ and ‘soft’ limiters. Hard limiters are the ones that you slam into with an unpleasant jerk as the engine’s power is suddenly cut. Soft limiters slow the revs more gradually, like the engine is pushing against a coil spring.
