Reflash for the Acura TSX/Accord CL9 refers to the process of modifying the electronic control unit (ECU) software to optimize the engine’s performance. Here are the main changes that can be achieved through a reflash:

Increased Power and Torque: By modifying various engine parameters, such as fuel and ignition maps, the reflash process can add approximately 20 horsepower and 20 Newton-meters of torque in the middle of the RPM range. Additionally, there can be a gain of up to 10 horsepower at the peak RPM. These enhancements result in improved acceleration and overall engine performance.

Rev Hang Deletion: Rev hang refers to the delay in reducing engine RPM during gear shifts. Through the reflash process, this rev hang is eliminated, allowing for smoother and more precise gear changes.

Speed Limit Deactivation: The speed limit restrictions are turned off, removing any artificial limitations on your vehicle’s top speed. This modification allows you to fully utilize the performance capabilities of your Acura TSX.

Throttle Response Optimization: The throttle response and sensitivity are adjusted to stage 1, providing a more immediate and responsive pedal feel. This modification enhances the overall driving experience by delivering improved throttle control and acceleration.

New Variable Timing Control (VTC) Maps: The VTC maps, which control the variable valve timing system, are updated to optimize engine performance across different RPM ranges. This enhancement can improve power delivery and torque characteristics throughout the engine’s operating range.

Revised VTEC Activation: The VTEC system, which controls valve lift and timing, is adjusted to activate between 4000 and 8000 RPM. The specific activation points are determined by the load conditions, engaging at 4000 RPM under maximum throttle or at 5500 RPM during cruise modes. This adjustment can provide a balance of power and efficiency.

New Fuel and Ignition Maps: Fuel maps are revised to maximize power output while also considering lower fuel consumption. By optimizing the fuel delivery and ignition timing, the reflash process can achieve improved engine performance and potentially better fuel efficiency.

Increased Rev Limit: The rev limit, which defines the maximum RPM the engine can reach, is raised to 8000 RPM. This modification allows for a wider power band and potentially higher top-end performance.
