In this article, LMR.com discusses everything you need to know about the 2 step rev limiter and how to use it to increase performance!
If you want to enhance your car's performance, a two step rev limiter is a valuable tool. It can help you achieve quicker launches and maximize your car's potential on the track. In this article, we'll explain a two step rev limiter and why you should consider purchasing one for your vehicle.
A two step rev limiter is an electronic device that allows you to control the RPM of your car's engine. It is designed to help you achieve the perfect launch by allowing you to set two different RPM limits: one with a lower RPM and the other at a higher RPM.
When you activate the two step rev limiter, your car's engine will rev up to the pre-set launch RPM limit while pressing the accelerator pedal and holding it there until you release the clutch. This allows you to build up power for a quicker and smoother launch. Once you release the clutch, the engine will jump to the higher RPM limit, giving you the maximum acceleration you need to take off.
The two step also cuts the ignition rather than cutting the fuel like the factory rev limiters. This is usually cut at a specific RPM lower than the main rev limiter for the purpose of building boost for launching better from a standstill. Once the ignition is cut, the unburnt fuel can enter and burn in the exhaust manifold and turbine housing. This spools the turbo and makes boost even though the engine isn’t under load. Limiting the revs, whether it is on the 2nd stage for engine protection or the 1st stage for better launches, all lead to a better driving experience.
There are several benefits of using a two step rev limiter, including:
Quicker launches: Using a two-step rev limiter, you can achieve quicker launches and get off the line faster than your opponents. This is particularly useful for drag racing, where the first few seconds of the race can make all the difference.
Better traction: With a two step rev limiter, you can optimize your car's traction by keeping the RPMs steady before launch. This allows your tires to gain better traction, helping you achieve a better launch and avoid wheel spin.
Protect your engine: By limiting the RPMs before launch, you can prevent engine damage and prolong the life of your engine. This is especially important for high-performance engines that are subject to more wear and tear.
Customization: two step rev limiters allow you to customize your launch RPM to suit your car's specific needs. This can help you achieve the best performance possible for your particular vehicle and driving style.
In conclusion, a two step rev limiter is a valuable tool for anyone looking to enhance their car's performance, particularly for drag racing. It allows you to achieve quicker launches, optimize traction, protect your engine, and customize your launch RPM to suit your car's specific needs. If you're serious about performance, consider investing in a two step rev limiter today!
