Is it safe to bounce off the rev limiter?
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.
Is it bad to rev 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.
Can you remove soft rev limiter?
How to remove the RPM limiter? This electronic command module which limits the RPM quantity in order to save your engine from being damaged cannot be physically removed. However, you have the possibility to change the ECU stock with a high performance ECU.
Why do cars have soft rev limiters?
Soft-cut limiters are a type of rev limiter that partially cuts off fuel to the engine. These limiters may also retard the ignition timing. 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.
Why do soft limiters exist?
Soft limiters cut the fuel, but do it more gradually, decreasing the engine’s juice supply so it runs increasingly lean, slowing and ultimately halting the engine’s acceleration. These normally set the maximum revs lower while the car is stationary, for example, or while the engine is still in a warm-up phase.
What happens if you bounce off the rev limiter?
You don’t want to bounce off the rev limiter unless you run something that cuts spark and not fuel… Most rev limiters on factory cars cut fuel. The result is the car gets into a dangerously lean condition. This results in detonation and will damage your engine.
Why does MY BMW rev limiter bounce so much?
Rev limiters that bounce do that because it cuts cylinders out, which effectively kills the engine for a very short period of time to get the RPMs down. The BMW is probably just limiting the how far the RPMs can go electronically.
How does a rev limiter work on a car?
Traditional rev limiters work by controlling the ignition and/or fuel. Fuel Control – Amount of fuel thrown in is controlled. This is used very carefully as effects of running lean at such high RPM can be detrimental to the engine health. In fact, lot of controllers completely shy away from it for good reason.
Why does my car rev up when in Park?
I’ve seen questions about engines revving when braking and when idling, but my engine revs way up (and stays up) whenever it’s in park–whether on startup or shifting to park. It doesn’t rev unusually like this in any other gear. What would be the most probable reasons?
