The Chevy Silverado is a popular pickup truck known for its power and performance. Some models have a speed limiter that restricts the vehicle’s maximum speed. This can be frustrating for drivers who want to push their trucks to their limits on the open road or track. Fortunately, there are ways to remove the speed limiter on your Chevy Silverado and unlock its full potential. But the problem is How to Remove Speed Limiter on Chevy Silverado.

In this article, we’ll explore various methods of removing the speed limiter, their work, and their importance on your Chevy Silverado so you can experience the thrill of driving at high speeds without any limitations.

What is Speed Limit?

A speed limit is a crucial legal regulation ensuring road safety. It sets the maximum speed at which a vehicle can be driven on specific roads. Speed limits aim to avoid accidents caused by excessive speeding, which has been identified as one of the leading causes of highway accidents.

Speed limits are determined based on various factors such as traffic conditions, weather, and road type. Similarly, highways have higher speed limits than city streets because fewer congestion and pedestrians are crossing the road.

Road signs displaying different speeds for different areas help drivers comply with the set regulations. Law enforcement officers use devices like radar guns to monitor vehicle speeds and ensure compliance with established laws.

What are Speed Limiters?

What are Speed Limiters?

Speed limiters are devices that control the speed of a vehicle, limiting it to a specific maximum speed. These devices can be found in various forms, like electronic systems, mechanical devices, and software programs. The primary goal of installing speed limiters is to reduce accidents caused by speeding vehicles on the road.

Speed limiters are becoming increasingly popular as more countries adopt laws to regulate vehicle speeds. In some countries such as the UK and Australia, Lorries weighing over 7.5 tons must have an automatic device that limits their speed to 56 mph or less on motorways.

Similarly, buses weighing more than 12 tonnes must have speed limiters at 62 mph or lower. Speed limiters can be programmed based on engine capacity, vehicle weight, and other technical specifications.

How Do Speed Limiters Work?

Speed limiters have three primary components: a speed sensor, a control module, and an actuator. The speed sensor measures the rotation of the wheels and transmits this information to the control module. The control module then compares this data with that particular vehicle’s pre-set maximum speed limit. If it detects that the vehicle exceeds this limit, it will send a signal to the actuator.

The actuator is responsible for limiting fuel or power delivered to the engine, slowing down or capping off its output performance, thereby controlling its top speed. This helps prevent drivers from exceeding safe driving speeds on highways and other roads where accidents can occur quickly due to high speeds.

Some speed limiters use the brakes to slow the vehicle down if it exceeds the speed limit. Once activated, these limiters automatically apply the brakes when they sense the car has exceeded a certain speed.

The effectiveness of this type of limiter is determined by how quickly it can respond to changes in speed and how accurately it can maintain a steady pace. Some newer models can adjust their settings based on road conditions or weather patterns, further improving their performance and reliability.

How to Remove Speed Limiter on Chevy Silverado?

How to Remove Speed Limiter on Chevy Silverado?

There are three ways to remove the speed limiter on your Chevy Silverado.

By using a Tuner:

By using a Tuner:

A tuner or programmer is an electronic device that can help you get the most out of your vehicle’s engine. These devices are designed to modify the engine management system, which controls various functions such as fuel delivery and timing. A tuner or programmer can increase horsepower, improve fuel efficiency, and adjust things like shift points by tweaking these settings. The tuner is used to remove the limiter on Chevy.

The process is relatively simple and involves using a tuner or programmer to communicate with your car’s onboard computer system.

The first step in removing a speed limiter is purchasing a tuner compatible with your vehicle. This device will allow you to access your car’s computer system and change its programming. Once you have the tuner, connect it to the OBD-II port underneath the steering column and select the speed limiter option from the menu.

After selecting this option, follow the-screen steps to disable the speed limiter. This typically involves selecting “disable” or “off” from a list of options the tuner software provides.

By Installing a Performance Chip:

By Installing a Performance Chip:

A performance chip, also known as an ECU (engine control unit) chip, is a device that can improve your Chevy’s horsepower and overall performance. This small electronic module alters the engine’s fuel map and timing to allow more air and fuel into the combustion chamber. Installing a performance chip in your Chevy is increased horsepower.

You can see gains ranging from 10-50 horsepower or more depending on the type of chip you choose. This boost in power translates to faster acceleration times, better towing capabilities, and an overall more enjoyable driving experience.

To install the chip:

Locate the OBD-II port, typically underneath the dashboard near the steering column. Once you have found it, plug in the performance chip and ensure it is installed correctly. After installing a performance chip speed limiter, remove the speed limiter.

After installation, take your Silverado for a test drive and feel the difference in power and acceleration. With increased horsepower and torque at your disposal, tackling inclines or accelerating onto highways will be smoother.

By Disconnecting the Wire:

By Disconnecting the Wire:

The electronic control module (ECM) controls the limiter, which receives signals from various sensors, including the speed sensor. This helps ensure drivers do not exceed the recommended speed limit, preventing accidents and ensuring road safety.

This sensor can be found on your vehicle’s transmission or rear differential. Once you have located it, look for the wire that connects it to the engine control module (ECM). This wire harness must be disconnected to turn off the speed limiter.

To disconnect the wire harness, unplug it from both ends. Ensure that you note where each end was plugged in so that you can reconnect them later if necessary. Once this is done, start up your vehicle and take it for a test drive without reconnecting the wire harness. You should immediately notice the difference in how fast your truck can go.
