The 1G Eclipse, a beloved model among car enthusiasts, has garnered attention for its performance potential. One of the significant upgrades that can enhance its drivability and power output is the installation of an APEXi Power FC ECU. In this article, we will explore the performance testing results of the 1G Eclipse after the installation of this ECU, focusing on drivability improvements and power gains.
Understanding the 1G Eclipse
The first-generation Eclipse, produced from 1990 to 1994, is known for its lightweight design and turbocharged engine options. It became a popular choice among tuners due to its potential for modifications and performance upgrades. The APEXi Power FC ECU is one such modification that can significantly enhance the vehicle’s performance.
What is the APEXi Power FC ECU?
The APEXi Power FC is a standalone engine management system that allows for precise tuning of the vehicle’s fuel and ignition maps. This flexibility enables users to optimize performance based on specific modifications and driving conditions. The ECU also features an easy-to-use interface for real-time adjustments, making it a popular choice among performance enthusiasts.
Testing Methodology
To evaluate the performance gains from the APEXi Power FC ECU, we conducted a series of tests on a stock 1G Eclipse. The testing process included:
- Baseline dyno runs to measure stock power output.
- Installation of the APEXi Power FC ECU.
- Custom tuning sessions to optimize performance.
- Post-installation dyno runs to measure power gains.
- Real-world drivability assessments on various road conditions.
Baseline Performance Measurements
Before the installation of the APEXi Power FC, the stock 1G Eclipse was tested on a dynamometer. The results showed:
- Peak horsepower: 135 hp at 6,000 RPM
- Peak torque: 130 lb-ft at 3,000 RPM
These figures provided a solid foundation for comparison after the ECU upgrade.
Installation of the APEXi Power FC ECU
The installation process of the APEXi Power FC ECU involved removing the stock ECU and connecting the new unit to the existing wiring harness. Following the installation, the ECU was configured using the APEXi software to ensure compatibility with the 1G Eclipse’s engine specifications.
Custom Tuning Sessions
After installation, multiple tuning sessions were conducted to optimize the fuel and ignition maps. This process involved:
- Adjusting fuel delivery to achieve optimal air-fuel ratios.
- Tweaking ignition timing for improved combustion efficiency.
- Monitoring engine parameters using the APEXi software.
The goal was to maximize power output while maintaining reliability and drivability.
Post-Installation Performance Measurements
Following the tuning sessions, the 1G Eclipse was subjected to another round of dynamometer testing. The results were impressive:
- Peak horsepower: 180 hp at 6,500 RPM
- Peak torque: 165 lb-ft at 3,800 RPM
This represented a significant increase in both horsepower and torque, showcasing the effectiveness of the APEXi Power FC ECU.
Drivability Improvements
In addition to power gains, the APEXi Power FC ECU also enhanced the drivability of the 1G Eclipse. Drivers reported:
- Smoother acceleration throughout the RPM range.
- Improved throttle response.
- Better engine stability under various driving conditions.
These improvements made the vehicle more enjoyable to drive, especially in everyday scenarios.
Real-World Testing
To further assess the performance of the 1G Eclipse with the APEXi Power FC ECU, real-world testing was conducted on different terrains, including:
- City driving with stop-and-go traffic.
- Highway cruising at various speeds.
- Mountain roads with steep inclines.
In each scenario, the vehicle demonstrated improved performance and responsiveness, making it a reliable option for both daily driving and spirited runs.
Conclusion
The performance testing of the 1G Eclipse with the APEXi Power FC ECU highlights the significant benefits of this upgrade. With notable power gains and enhanced drivability, the APEXi Power FC ECU proves to be a valuable investment for enthusiasts looking to unlock the full potential of their 1G Eclipse.
For those considering this modification, it is essential to ensure proper installation and tuning to maximize the benefits and maintain engine reliability.
