What is soft cut limiter?

Soft-cut limiters are a type of rev limiter that partially cuts off fuel to the engine. If using a soft-cut rev limiter, the engine will start to cut fuel or retard ignition timing before the set RPM until it slowly reaches it and remains there.

What happens if you remove the rev limiter?

If you remove the rev limiter without much expertise, you run the risk of damage to the gearbox, engine or other components. In addition, the change ensures that the wheels and tires are exposed to a greater load.

Why do soft limiters exist?

The goal of a soft limit is to curb further acceleration towards the hard limit, and the hard limit exists to protect the engine from damage. I’ve owned many cars, and none of mine have had a soft limit, just a hard limiter.

Does revving damage engine?

When you rev your engine, you place additional and unnecessary stress on your car and its engine. This is imperative when it’s cold outside—revving your engine before it has had time to warm up is especially damaging, as the engine’s oil hasn’t had sufficient time to circulate and properly lubricate your car.

What is a hard cut limiter?

A hardcut limiter cuts the fuel at the set RMP limit. This changes how the engine behaves and changes the sound of the vehicle at the RMP limit. This feature is usually used when the ECU remap is done to change how the engine behaves. The sound of the hardcut can vary depending on the Engine, Turbo and Exhaust.

Does hitting the rev limiter hurt the engine?

The rev limiter does not hurt your engine, but bouncing the car off the rev limiter continuously is not a good idea either. If you hit the rev limiter before you shift it slows your run and wastes fuel.

How many times can you redline a car?

Most consumer cars can be run up to redline, in theory, regularly as part of driving, without causing any issues. I regularly hit 6k on my old car, which had a redline at about 6.5 to 7.

What is the difference between a hard and soft rev limiter?

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.

What is the difference between soft cut and hard cut limiters?

This is a last resort rev limiter that most people would never hit in their lives as soft cut limiters are set to work properly. Hard cuts are generally set as an emergency higher RPM cut incase the soft cut doesnt have the required effect. On standard cossies they set about 300rpm higher than the soft cut IIRC

What is a rev limiter and what does it do?

Explaining a rev limiter isn’t rocket science. Sorry for stating the bleeding obvious, but they limit the maximum speed an engine can achieve. Equally plain is that they’re there to prevent an engine damaging itself by extending beyond its own limits.

How do soft limiters work in a car?

Soft limiters act similar to how an unlimited engine behaves – the RPM just stabilizes at a given point, and the limit is seen well before it is reached. Early symptoms of spinal muscular atrophy may surprise you. Signs of spinal muscular atrophy can be easily ignored.
