The 2G Eclipse, a beloved model among car enthusiasts, has long been a canvas for performance upgrades. With the right modifications, these vehicles can achieve impressive power outputs. In this article, we explore the real-world results of a 2G Eclipse equipped with an HKS exhaust system and an ECU reflash, culminating in an impressive 280 horsepower at the wheels.
Understanding the 2G Eclipse
The second generation of the Mitsubishi Eclipse, known as the 2G Eclipse, was produced from 1995 to 1999. This model gained a reputation for its lightweight design and turbocharged engines, making it a popular choice for tuners. The 2G Eclipse comes in various trims, but the GS-T and GSX models are particularly favored for performance upgrades.
Performance Modifications
To achieve the remarkable 280 horsepower at the wheels, several key modifications were made to the vehicle. These modifications include the installation of an HKS exhaust system and an ECU reflash, among other enhancements.
HKS Exhaust System
The HKS exhaust system is renowned for its high-quality construction and performance benefits. By reducing back pressure and improving exhaust flow, this system allows the engine to breathe more freely, thus enhancing power output. The benefits of the HKS exhaust system include:
- Increased horsepower and torque
- Improved throttle response
- Enhanced sound quality
ECU Reflash
An ECU reflash is a critical step in maximizing the performance of any modified vehicle. By recalibrating the engine control unit, tuners can optimize fuel maps, ignition timing, and boost levels to match the new hardware. The advantages of an ECU reflash include:
- Improved fuel efficiency
- Better overall engine performance
- Customization options for specific driving needs
Real-World Performance Results
After the installation of the HKS exhaust system and the ECU reflash, the 2G Eclipse was taken to the dyno for testing. The results were impressive, with the vehicle achieving 280 horsepower at the wheels. This performance figure is significant when considering the weight and design of the 2G Eclipse.
Dyno Testing Results
The dyno testing provided a comprehensive overview of the vehicle’s performance metrics. Key findings from the testing included:
- Peak horsepower: 280 hp at the wheels
- Peak torque: 300 lb-ft
- Power band: 3,500 to 7,500 RPM
Driving Experience
The enhancements made to the 2G Eclipse not only improved its power output but also transformed the driving experience. With the HKS exhaust system, the car produces a deep, aggressive sound that resonates with performance enthusiasts. Additionally, the ECU reflash ensures that the vehicle responds quickly to throttle inputs, making it a joy to drive.
Handling and Responsiveness
Alongside the power upgrades, handling improvements are essential for a well-rounded performance vehicle. The 2G Eclipse can be further enhanced with suspension upgrades, which improve cornering stability and overall driving dynamics. Key aspects to consider include:
- Upgraded shocks and struts
- Performance sway bars
- Lowering springs for improved center of gravity
Conclusion
The combination of an HKS exhaust system and an ECU reflash has proven to be a powerful modification strategy for the 2G Eclipse. Achieving 280 horsepower at the wheels is a testament to the potential of this vehicle when equipped with the right performance parts. For enthusiasts looking to enhance their 2G Eclipse, these modifications offer a pathway to significantly improved performance and driving enjoyment.
