by

The Mitsubishi Eclipse has long been a favorite among car enthusiasts, known for its sporty design and performance capabilities. One of the most popular tuning devices for this vehicle is the COBB Accessport.

What is the COBB Accessport?

The COBB Accessport is a versatile tuning tool designed to optimize vehicle performance. It allows drivers to adjust engine parameters, monitor performance data, and install custom tunes.

Benefits of Using a COBB Accessport

  • Increased Horsepower: The primary benefit is the potential increase in horsepower and torque.
  • Improved Throttle Response: Enhanced throttle response leads to a more engaging driving experience.
  • Custom Tuning Options: Users can install pre-configured maps or create their own custom tunes.
  • Data Monitoring: The Accessport provides real-time data monitoring for various engine parameters.

How Much Horsepower Can You Expect?

The increase in horsepower from using a COBB Accessport can vary based on several factors, including the specific model of the Mitsubishi Eclipse, the engine type, and any additional modifications made to the vehicle.

Stock vs. Tuned Performance

On a stock Mitsubishi Eclipse, the horsepower output typically ranges from 140 to 260 horsepower, depending on the engine variant. After installing a COBB Accessport and applying a suitable tune, drivers can expect an increase ranging from 15 to 50 horsepower.

Factors Affecting Horsepower Gains
