In the world of vintage luxury cars, the Rolls-Royce Corniche of the 1980s holds a special place. Its stunning design combined with a powerful engine and the ultimate in comfort makes it a unique piece of automotive history. However, as with any classic car, keeping it in the best possible condition requires knowledge and dedication. One of the most crucial aspects you need to pay attention to is the fuel injection system. Optimizing it could significantly improve your Rolls-Royce’s performance and fuel economy. In this article, you’ll discover how to achieve this effectively.
Understanding the Fuel Injection System
Before jumping into the optimization process, it’s critical to have a basic understanding of the fuel injection system in your Rolls-Royce Corniche. Introduced in the late 1970s, fuel injection systems replaced carburetors in most vehicles, offering better control over fuel delivery and more efficient fuel consumption.

A fuel injection system’s primary function is to deliver fuel to the engine’s cylinders in a precise and controlled manner. It includes several components including fuel pump, fuel injectors, pressure regulators, and an electronic control unit (ECU) that manages these operations. Understanding these parts and their roles can help you identify any issues and know what to improve.
Regular Maintenance
Regular maintenance is the key to keeping your fuel injection system running optimally. Neglecting it may result in poor engine performance or even serious damage.

Firstly, make sure to change your fuel filters routinely. A dirty or clogged fuel filter can obstruct the flow of fuel, reducing the efficiency of your fuel injection system. Replacing it at recommended intervals can ensure that your system gets clean fuel, resulting in better engine performance.
Secondly, check your fuel injectors regularly for clogs or leaks. Clogged injectors can lead to a lean fuel mixture, causing your engine to run inefficiently, while a leak can lead to fuel wastage. Having your injectors cleaned every 15,000 miles or so can prevent these issues.
Upgrading Your Fuel Injectors
If you are looking for significant improvements in your Rolls-Royce’s performance, consider upgrading your fuel injectors. Modern injectors offer superior fuel atomization, meaning they can more effectively mix fuel with air, leading to more efficient combustion.
When choosing new injectors, consider their flow rate, which is measured in pounds of fuel per hour. A higher flow rate allows for more fuel delivery, which can increase horsepower. However, too high a flow rate can lead to a rich fuel mixture, causing poor fuel economy and potentially damaging your engine. It’s important to choose an injector with a flow rate suited to your engine’s needs.
Tuning Your ECU
The last, but not least, aspect of optimizing your fuel injection system is tuning your ECU. A tuned ECU can improve engine performance by adjusting the timing and quantity of fuel injected into the engine.
There are two main types of ECU tuning: remapping and chip tuning. Remapping involves modifying the existing program in your ECU to change how it controls the fuel injection system. This can be done using specialized software and can result in improved fuel economy and better throttle response.
Chip tuning, on the other hand, involves replacing the chip in your ECU with a performance-oriented one. This can provide more significant improvements in performance but is typically more expensive and complex than remapping.
Remember, ECU tuning should ideally be done by a professional to avoid damaging your engine or voiding your warranty.
By understanding, maintaining, and upgrading your fuel injection system and tuning your ECU appropriately, you can significantly improve the performance and fuel economy of your 1980s Rolls-Royce Corniche. Keep in mind that these modifications should be done responsibly and with consideration for the car’s original specifications to maintain its integrity as a classic vehicle.
Enhancing the Fuel Pump and Pressure Regulators
To optimize your 1980s Rolls-Royce Corniche, pay attention to the fuel pump and pressure regulators. As critical components of the fuel injection system, they ensure the smooth flow of the fuel to the engine.
The fuel pump in the Rolls-Royce Corniche, as with many vintage Rolls-Royce and Bentley models, is designed to deliver a consistent flow of fuel to the engine. However, due to wear and tear, the fuel pump may lose its efficiency over time. This can result in an inconsistent fuel supply, which can affect engine performance. You might consider upgrading your fuel pump to a modern variant that can offer better performance and longevity.
Similarly, the pressure regulator controls the pressure of the fuel supplied to the injectors. A worn-out or faulty regulator can lead to an uneven fuel supply, resulting in a rich or lean mixture. Upgrading to a high-performance pressure regulator can help maintain an optimal fuel pressure, ensuring a more efficient combustion process.
Bear in mind that while upgrading, it’s vital to choose components that are compatible with your Rolls-Royce Corniche. You must strike a balance between improved performance and maintaining the originality of your classic vehicle.
Maintaining the Automatic Transmission and Air Conditioning
While the fuel injection system is crucial for your Rolls-Royce’s performance, other systems also play an essential role. The automatic transmission and air conditioning are two such systems that demand attention.
The transmission system in the 1980s Rolls-Royce Corniche and other models like the Silver Shadow and Silver Spirit is a four-speed automatic, which ensures a smooth and luxurious drive. Regular servicing of the transmission system, including changing the transmission fluid and checking the clutch and brake pump, can prevent issues like gear slipping and ensure a smooth ride.
The air conditioning system of the Corniche, equipped with advanced climate control, contributes to the car’s comfort and luxury. Regular maintenance, including cleaning the vents and replacing the filters, can ensure effective climate control.
Maintaining the pristine condition of a classic vehicle like the 1980s Rolls-Royce Corniche requires time, effort, and a deep understanding of its various systems. From the fuel injection to the automatic transmission and climate control, every aspect contributes to the car’s overall performance and comfort.
By performing regular maintenance, upgrading components like fuel injectors, fuel pump and pressure regulators, and tuning the ECU, you can not only optimize its performance and fuel economy but also preserve its timeless appeal. Remember, while seeking performance upgrades, it’s equally crucial to respect the car’s original specifications to maintain its authenticity and prestige status.
Enjoy the rewarding experience of driving your optimally tuned Rolls-Royce Corniche, a testament to the elegance and engineering prowess of the past. Take pride in being the custodian of a piece of automotive history that continues to inspire modern luxury vehicles, including the latest Rolls-Royce and Bentley Continental models.
