You’re cruising down the highway, late for an important meeting. You glance at your speedometer and see it’s already pushing the legal limit. You think to yourself, “If only I could bypass this speed limiter…”
Many car enthusiasts have shared this thought at some point. The idea of unleashing your car’s full potential with a simple OBD scan sounds almost too good to be true. But is it really that simple? Can you actually remove speed limiters with an OBD scanner? Let’s dive in and find out.
Understanding Speed Limiters and OBD Scanners
Before we answer the burning question, let’s break down what speed limiters and OBD scanners are, and how they interact with your car.
Speed Limiters: A Necessary Evil?
Speed limiters are like the responsible friend in a car chase scene, always reminding you to slow down. They are pre-set electronic restrictions within your car’s Engine Control Unit (ECU) that prevent your vehicle from exceeding a certain speed.
Why do manufacturers put these limitations in place?
- Safety: This is a primary concern. Speed limiters help prevent accidents by keeping your speed in check.
- Legal Compliance: Many countries have specific regulations regarding vehicle top speeds, and manufacturers must comply with these laws.
- Tire Safety: Your tires are designed to operate safely within a specific speed range. Exceeding this limit can lead to dangerous blowouts.
OBD Scanners: Your Car’s Personal Doctor
Think of an OBD (On-Board Diagnostics) scanner as a window into your car’s soul (or at least its computer system). These handy devices plug into your car’s OBD-II port and can read diagnostic trouble codes, monitor engine performance, and even access certain vehicle settings.
Can They Work Together to Remove Speed Limiters?
Here’s the truth: while some advanced OBD scanners might allow you to view certain speed-related settings in your car’s ECU, they cannot directly remove or modify speed limiters in most modern vehicles.
Why not?
- Security: Car manufacturers take vehicle security very seriously. Speed limiters are often deeply integrated into the ECU’s software and protected by encryption to prevent tampering.
- Liability: Allowing easy modification of speed limiters could expose manufacturers to significant legal risks.
Imagine this: “I tried to tell him to slow down,” your friend, James, a mechanic at a local garage, says, shaking his head. “But he insisted his Honda Civic could handle like a Formula One car after using some OBD software he found online.” Stories like this highlight the potential dangers of tampering with safety-critical systems.
Exploring Alternatives and Considerations
While removing speed limiters through OBD scanners is generally not feasible, there are other avenues you might explore:
- ECU Tuning: This involves reprogramming your car’s ECU, which can potentially modify speed limiters among other performance parameters. However, this is a complex procedure that should only be performed by qualified professionals.
- Aftermarket Performance Chips: These chips can alter various engine parameters, including speed limits in some cases. However, it’s crucial to choose reputable brands and ensure compatibility with your vehicle.
Remember: Always prioritize safety and legal compliance when considering any modifications to your car.

FAQs about Removing Speed Limiters with OBD Scanners
Let’s address some common questions car owners often have:
Q: Are there any OBD scanners specifically designed to remove speed limiters?
A: While some scanners might advertise this capability, it’s highly unlikely they can bypass the sophisticated security measures in modern vehicles.
Q: Is it legal to remove or tamper with my car’s speed limiter?
A: Laws vary significantly by region. In many places, it’s illegal to modify a vehicle’s speed limiting system beyond what the manufacturer allows.
Q: What are the risks of attempting to remove the speed limiter myself?
A: You could damage your car’s ECU, void your warranty, and even compromise your safety on the road.

Beyond Speed: Exploring Other OBD Capabilities
While removing speed limiters might be off the table for most, OBD scanners offer a plethora of other benefits:
- Diagnose Engine Problems: Quickly identify engine issues and get them resolved faster.
- Monitor Vehicle Performance: Track fuel efficiency, engine load, and other vital parameters.
- Reset Warning Lights: Easily reset check engine lights and other warning indicators after addressing the underlying issues.
Take Control of Your Car’s Health, Not Its Speed
OBD scanners are powerful tools for understanding and maintaining your vehicle’s health. While the allure of removing speed limiters might be tempting, it’s crucial to prioritize safety, legality, and responsible vehicle modification.
