Can you take the governor off a golf cart? Yes, you can take the governor off a golf cart. This process, often called golf cart speed limiter removal, helps owners unlock more speed from their vehicles. However, it is vital to know the legal rules where you drive. Removing the governor changes how fast your cart goes. This article shows you the steps for disabling golf cart governor systems on different cart types. We aim to help you with how to increase golf cart speed safely and correctly.
Why People Remove Golf Cart Governors
Golf carts come from the factory set to a safe, slow speed. This is often for safety reasons or to meet local street-legal limits. Many owners want more zip for off-road fun or on large properties. Unrestricting golf cart performance gives the driver more control over the vehicle’s top speed.
Different carts use different ways to limit speed:
- Mechanical Governor: Found mainly on older gas carts. It uses weights or linkages.
- Electronic Governor: Common in modern electric carts. It uses the controller or the speed chip.
Safety First: Before You Start Modifying
Modifying your golf cart’s speed settings is a big step. Always think about safety before you try golf cart engine restriction bypass.
- Check Local Laws: Many places have strict laws about how fast a golf cart can drive on public roads. Speeding can lead to fines or insurance issues.
- Understand Warranty: Tampering with the governor usually voids any factory warranty you might have left.
- Brakes and Tires: Faster speeds put more stress on your brakes and tires. Make sure they are in excellent working order before increasing speed.
Section 1: Taking Off the Governor on Gas Carts (Mechanical Systems)
Gas golf carts (like many older E-Z-GO models) use a physical governor attached to the engine’s throttle linkage. This is a mechanical device that physically stops the throttle from opening all the way.
Tools You Will Need
- Basic wrench set or socket set.
- Screwdrivers (flathead and Phillips).
- Pliers.
- Safety glasses.
Steps for Removing the Mechanical Governor
The steps for removing speed governor on E-Z-GO or similar gas carts involve locating and adjusting or removing the governor assembly itself.
Locating the Governor
The governor is usually mounted near the carburetor or on the side of the engine block. It connects via rods or cables to the throttle linkage.
Method 1: Adjusting the Governor Linkage (Partial Speed Increase)
Sometimes, you don’t need full removal. A simple adjustment can yield a speed boost.
- Find the Adjustment Nut/Bolt: Look closely at the governor assembly. There is usually a lock nut or bolt that sets the maximum travel of the throttle linkage.
- Loosen the Lock Nut: Use a wrench to loosen the nut holding the setting in place.
- Adjust the Stop Bolt: Slowly turn the adjustment bolt outward (this usually allows more throttle). Turn it just a little bit at a time.
- Test and Tighten: Tighten the lock nut back down. Test the cart at low speed. If it feels too jerky or the engine strains, the adjustment is too aggressive. Repeat slowly until you find a good spot.
Method 2: Bypassing the Governor Linkage (Full Removal)
For a complete bypass, you physically disconnect the governor from controlling the throttle.
- Disconnect Linkage: Carefully disconnect the rod or cable running from the governor to the throttle plate on the carburetor. You may need to remove small clips or pins.
- Lock the Throttle: Now you need to set the throttle cable/rod to stay open slightly more than normal. You can often use a small piece of rigid wire or a zip tie to hold the throttle cable linkage open to the desired level. Be careful not to hold it so open that the engine races uncontrolled.
- Secure the Governor: While some remove the entire unit, often it’s easier to just disconnect the moving parts and let the governor sit idle. If you remove it completely, you must ensure the throttle linkage returns fully closed when you let off the gas pedal.
Important Note: When adjusting a gas engine governor, you are essentially overriding the engine’s internal speed control. If you open the throttle too much without changing fuel/air mixtures (which is complex), you risk overheating or damaging the engine pistons. Moderate adjustments are safer for mechanical governors.
Section 2: Modifying Electric Carts (Electronic Control)
Electric golf carts rely on the Electronic Speed Controller (ESC) to manage power flow to the motor. Speed limits are programmed into this controller or managed via separate modules. This process relates closely to Club Car golf cart governor adjustment or altering the settings on other brands.
Tools and Knowledge Required
- Multimeter (optional, for checking connections).
- The specific wiring diagram for your cart model (highly recommended).
- Basic electrical knowledge.
Common Electric Cart Types and Removal Methods
E-Z-GO TXT/Medalist (Series Carts)
Older E-Z-GO series carts often have a simple resistor or connection point that limits speed.
- Locate the Forward/Reverse Switch: On many older models, the speed setting is controlled by a sequence of connections in the forward/reverse switch assembly.
- Check the Run Key Switch: Speed settings are often determined by which key position is active (e.g., “Tow/Run” switch settings). Ensure your key switch is set to the highest performance setting, often labeled “Run.”
- Bypassing Speed Settings: In some older E-Z-GO models, you might find jumper wires between terminals on the speed controller harness that correspond to different speeds. Consult your specific model manual for removing speed governor on E-Z-GO if you have a series cart.
E-Z-GO PDS/TXT Freedom Carts (Programmed Carts)
These carts use programmable controllers (like the Curtis controllers). Speed limiting is software-based.
- Controller Access: Locate the main speed controller, usually under the front cowling or seat.
- Programmer Required: To change settings, you usually need an official handheld programmer tool specific to that controller brand (e.g., Curtis Programmer).
- Adjusting Parameters: Using the programmer, you can access parameters like “Maximum Throttle Percentage” or “Top Speed Setting.” Increase this value from the default (often 80%) up toward 100%. This is the most precise way for electronic golf cart governor override.
Club Car DS/Precedent Carts (Series and IQ Systems)
Club Car speed management heavily relies on the IQ system for newer carts.
- Key Switch Test: Like E-Z-GO, ensure the key switch is set to the fastest setting if multiple speed keys are installed.
- Controller Reprogramming: For IQ system carts, changing speeds requires an IQ Programmer handheld device specific to Club Car. This allows fine-tuning for Club Car golf cart governor adjustment. You can often increase the speed limit from 12 mph to 19+ mph depending on your motor/controller combination.
Yamaha Carts (Often Use Speed Chips)
Yamaha carts, especially older G16/G22 models, often utilize removable speed chips or jumpers located near the controller.
- Locating the Speed Chip: On many Yamaha controllers, there is a small module or jumper plug. Different chips correspond to different speed settings (e.g., “High Speed Chip” or “Marathon Chip”).
- Swapping the Chip: If you have the high-speed chip installed, your cart is already unrestricted for that controller type. If a low-speed chip is present, you must swap it out for the high-speed version or remove it entirely if the harness allows for a full bypass. This is key for Yamaha golf cart speed chip removal.
Section 3: The Advanced Method – Controller Replacement
If you want a significant speed boost beyond what simple adjustments or chip swaps allow, you must upgrade the controller. This is the ultimate form of golf cart engine restriction bypass.
When a New Controller is Necessary
- Your existing controller cannot handle higher speeds (it’s designed to limit power).
- You are installing a higher-powered motor or larger tires.
- You are moving from a 36V system to a 48V system (which requires a compatible controller).
How a New Controller Helps
A high-performance controller (often rated 400 or 500 amps, compared to stock 200-250 amps) removes the manufacturer’s electronic ceiling on speed and torque. This is the most effective cart speed control module bypass.
- Select the Right Controller: Match the controller’s voltage (36V, 48V) and motor type (Series or AC/PDS) to your existing system. Look for controllers specifically marketed for speed upgrades.
- Install New Controller: Replace the old unit following the wiring diagram carefully. High-amperage controllers require thicker gauge wiring and heavier-duty solenoids to handle the increased current safely.
- Install Speed Sensor (If Needed): AC systems or advanced controllers might require installing a separate speed sensor if the controller doesn’t integrate it, ensuring accurate readings for the new speed limits you program in.
Section 4: Performance Gains and Considerations
After successfully performing golf cart speed limiter removal, you will notice a distinct difference in acceleration and top speed. However, these changes come with important trade-offs.
Speed vs. Torque
When you increase speed by reducing governor limits, you are often reducing torque (pulling power).
- If you adjust the throttle linkage (Gas Carts): The engine might struggle on hills because it cannot pull enough air/fuel mix at high RPMs to maintain power.
- If you increase controller amps (Electric Carts): You get more speed, but the increased current draw heats up the motor and batteries faster.
Battery Life Implications (Electric Carts)
Running at higher speeds drains batteries much faster. If you move from 12 mph to 20 mph, you might see your range cut by 30% to 40% because the motor is demanding more power constantly.
| Speed Setting Change | Expected Impact on Range | Motor/Controller Heat | Best Use Case |
|---|---|---|---|
| Minor Adjustment (1-3 mph) | Minimal loss (5-10%) | Slight increase | Light neighborhood use |
| Full Removal/Programmed Max | Significant loss (30%+) | High | Off-road or controlled tracks |
| Controller Upgrade | Moderate loss, better sustained power | Manageable with good wiring | Heavy use requiring sustained speed |
Tire Size Matters
When attempting how to increase golf cart speed, tire size plays a huge role. A speed increase achieved by governor removal will feel much greater if you have already installed larger tires.
- Larger Tires: Turning the wheel one rotation moves the cart further. If you have a 23-inch tire instead of a 20-inch tire, you effectively gain about 15% speed instantly, regardless of the governor setting.
- Controller Recalibration: If you upgrade tires and remove the governor, you must recalibrate the controller using the programmer tool. If you don’t, the speedometer (if you have one) will be wrong, and the cart might not shift gears correctly.
Section 5: Reversing the Process
What if you need to return your cart to factory settings, perhaps to sell it or meet new local regulations? Reversing the process is usually straightforward.
Reversing Gas Cart Governor Changes
- Reattach Linkages: If you disconnected the throttle cable from the governor, reconnect it exactly as it was. If you modified the throttle stop bolt, return it to its original position.
- Verify Idle: Start the engine and ensure that when the gas pedal is fully released, the throttle plate closes completely, allowing the engine to idle smoothly without racing.
Reversing Electronic Changes
- Reset Controller Program: If you used a programmer, plug it back in, go to the settings menu, and select the “Restore Factory Defaults” option. This returns all amp limits, speed limits, and acceleration curves to stock settings.
- Replace Chips (Yamaha): If you swapped a speed chip, reinstall the original, lower-speed chip.
- Check Wiring: If you added bypass wires or jumpers, remove them carefully and restore the wiring harness to its original configuration.
Conclusion
Golf cart speed limiter removal offers a satisfying performance upgrade for many owners. Whether you are tackling a mechanical linkage on an older gas model or diving into the software settings for electronic golf cart governor override on a modern electric cart, preparation is key. Always prioritize safety, check local laws, and ensure your cart’s braking and electrical systems can handle the extra speed. A successful modification involves detailed work, whether that means disabling golf cart governor physically or digitally reprogramming the speed controls.
Frequently Asked Questions (FAQ)
Q: Will removing the governor cause my golf cart motor to burn out?
A: If you only remove the governor slightly or reprogram the controller within safe factory limits, the risk is low. However, if you drastically change the wiring (like installing very high-amperage controllers without upgrading motor magnets or wiring), the motor will draw too much current, overheat, and fail quickly.
Q: Is it illegal to remove the governor on my golf cart?
A: This depends entirely on where you plan to drive the cart. In private communities or closed courses, it is usually fine. On public streets, driving a cart faster than the posted local speed limit for carts is illegal, regardless of whether the governor is physically present.
Q: What is the easiest way to increase the speed on a Club Car DS?
A: The easiest way is often to check the key switch setup (if it has a multi-speed key) or to use an IQ programmer to slightly increase the maximum throttle input percentage in the controller settings for Club Car golf cart governor adjustment.
Q: Do electric golf carts actually have a physical governor?
A: Most modern electric golf carts do not have a physical governor attached to the motor like gas carts do. Their speed limit is controlled electronically via the main speed controller, making the process closer to electronic golf cart governor override or reprogramming.
Q: How much speed can I expect after modification?
A: This varies widely. A mild adjustment might yield 1–3 mph. A full controller upgrade combined with larger tires can push speeds from a stock 12–15 mph up to 25–30 mph, depending on the cart’s base architecture.
