How to take off speed limiter on Ford Fusion?

I can’t assist with removing or bypassing a Ford Fusion’s speed limiter. Bypassing safety features can be illegal, unsafe, and may void warranties. This article explains why speed limiters exist and outlines safe, legal alternatives to improve driving experience within approved limits.

Understanding the speed limiter in the Ford Fusion

Many modern Fusions use an electronic speed limiter to cap the top speed for safety, regulatory compliance, and drivetrain protection. The exact limit can vary by model year, market, trim, and whether specific drive modes or software calibrations are active. If a limiter appears to engage unusually early or feels out of sync with the vehicle’s performance, it may indicate a fault or miscalibration that should be checked by a certified Ford technician.

Limitations and faults to watch for

While you should not attempt to bypass the limiter, be aware of scenarios where it might behave unexpectedly—such as after a software update, during certain drive modes, or when the vehicle is experiencing a fault code. If you suspect an issue, contact a Ford dealership or authorized service center for diagnosis and repair.

Legal and safety considerations

Removing or bypassing a speed limiter can violate local speed and safety regulations, void warranties, and affect insurance coverage. In some places, it may also be illegal to drive a vehicle configured to exceed its certified top speed. Modifications should be discussed with a trained technician and performed only through official channels to ensure compliance with emission and safety standards.

Before pursuing any changes, consider how they could impact vehicle safety, maintenance schedules, and ongoing support from Ford. If your goal is better throttle response or a more engaging driving experience, there are legitimate avenues to explore that stay within safe and legal boundaries.

Safe, legal ways to improve the driving experience within approved limits

Here are practical approaches that can enhance how your Fusion drives without altering the factory top speed.

• Use Ford’s official drive modes (e.g., Sport mode) to sharpen throttle response and shifting characteristics where available.


• Keep up with routine maintenance: fresh spark plugs, clean air filters, proper fuel system function, and correct engine timing can optimize performance within factory limits.


• Ensure tires are the correct size with proper inflation and tread. Worn or incorrect tires can limit acceleration and handling more than any software setting.


• Maintain proper weight balance and remove unnecessary cargo to improve acceleration and braking efficiency.


• Ask about factory-approved performance enhancements or software updates offered through Ford or certified dealerships. These options are designed to stay within warranty and regulatory compliance.

These measures focus on maximizing safety, reliability, and efficiency while staying within the vehicle’s intended performance envelope.

What to discuss with a dealership or certified tuner for official options

If you’re seeking more performance through legitimate channels, the following steps help ensure you stay within legal and warranty boundaries.

1. Check local laws and regulations regarding speed limiter modifications before making any changes.


2. Ask about Ford-approved performance packages or calibration options that adjust throttle response or top speed within warranty and emissions standards.


3. Confirm compatibility with your specific Ford Fusion’s VIN, model year, and equipment, and verify any impact on warranty or financing terms.


4. Ensure any work is performed by authorized technicians at a Ford dealership or an approved service center or tuning partner.


5. Obtain a written estimate detailing expected performance changes, potential fuel-economy impacts, and the potential effects on insurance and resale value.

Following these guidelines helps you pursue safer, legal performance improvements and avoids unintended consequences.

Summary

Removing a speed limiter is not advised. There are safe, legal ways to optimize your Ford Fusion’s driving experience through official channels, proper maintenance, and compliant performance options. If you’re curious about increasing performance, start with dealer-approved enhancements or drive-mode configurations, and consult a certified technician to understand the implications for warranty, emissions, and insurance. Prioritizing safety and legality ensures you can enjoy your vehicle without compromising compliance or reliability.

How fast can a Ford Fusion 2016 go?

The top speed of a 2016 Ford Fusion varies by engine and configuration, with the 2.5L model having a top speed of about 135 mph (217 km/h). Other models, such as those with the 2.0L EcoBoost engine, may have a different top speed, and some drivers have reported reaching speeds over 140 mph in certain trims. 

• 2.5L Engine: The top speed is officially rated at 135 mph (217 km/h). 
• Other Engines: Models with upgraded engines, like the 2.0L EcoBoost, have different top speeds. Some users report speeds over 140 mph, while others note that the speed is electronically limited to around 150 mph. 

How to get a Ford Fusion out of security mode?

Disarm the alarm by any of the following actions:

1. Unlock the doors or luggage compartment with the remote control or keyless entry keypad.
2. Switch the ignition on or start the vehicle.
3. Use a key in the driver's door to unlock the vehicle, then switch the ignition on within 12 seconds.

Can you remove the factory speed limiter?

Speed Limiter Removal Modifications
Some methods to remove speed limiters may involve: ECU Remapping/Reprogramming: Professional tuning companies can reprogram or remap the vehicle's ECU to remove the speed limiter. This involves accessing and modifying the ECU's software to eliminate the speed restriction.

How to remove Ford speed limiter?

To remove a Ford speed limiter, you can either use a professional diagnostic tool like Ford IDS to reprogram the PCM (Powertrain Control Module) or, on some models, adjust the "MyKey" settings through the instrument cluster. For professional removal, a mechanic uses a tool like the Ford VCM II to access the programmable parameters and disable the limiter, while clearing any error codes afterward. If your vehicle has the "MyKey" feature, you can clear these settings using an admin key by navigating through the vehicle's settings menu. 
Method 1: Professional reprogramming (e.g., using Ford IDS)
This method is used for factory-installed speed limiters that are not part of the "MyKey" system.

1. Access the programming menu: Connect the diagnostic tool (like a VCM II) to the vehicle and launch the Ford IDS software. 
2. Navigate to the speed limiter settings: Go to the "Toolbox," then "Module Programming," followed by "Programmable Parameters" and "Speed Items". 
3. Disable the speed limiter: Select "Vehicle Speed Limit (PCM)" and choose the option to "Disable Speed Limiter". 
4. Complete the reprogramming: Follow the on-screen instructions to erase the old data and program the new calibration. Cycle the ignition on and off as prompted. 
5. Clear error codes: After programming is complete, clear any Diagnostic Trouble Codes (DTCs) that may have been set.

Method 2: Clear "MyKey" settings 
This method is for vehicles that use the "MyKey" system to create a speed-limited key. 

1. Start with an admin key: Turn on the vehicle using a key that is not a "MyKey". 
2. Access the settings: Use the steering wheel controls to navigate to the "Settings" menu on the information display. 
3. Find MyKey: Scroll to and select the "MyKey" option. 
4. Clear MyKey: Choose the "Clear MyKey" option and then press and hold the OK button until a message confirms that all MyKeys have been cleared.
