Dear S660 owners, we apologize for the long wait. Honda Flash Pro, the engine ECU tuning tool for the Honda S660 (JW5), is now complete. Flash Pro allows you to complete ECU tuning simply by installing pre-tuned calibration data (Flash Pro data).

It's also an excellent tuning tool that allows you to customize your vehicle's setup.

The standard data set includes three stages, Stages 1 through 3, each with optimized fuel mixture and ignition timing, each with its own unique characteristics.

Stage 1 maintains boost pressure at the same level as stock while canceling throttle control, a self-regulatory measure for horsepower, for smooth power delivery up to high RPMs.

Stage 2 is a light tune with increased boost, providing torqueful driving even at low speeds.

Stage 3 is a high-tune tune with even higher boost, providing powerful driving across the entire range.

Choose from these three data sets to suit your driving stage and the tuning style you're aiming for.

Of course, another advantage of Flash Pro is that you can use this base data to create a setup that suits your vehicle. Enjoy your S660 to the fullest with HONDATA Flash Pro, which supports a variety of tuning styles.

All data available at this time is for high-octane specifications, with regular specifications currently under development.

Main adjustable items

• boost pressure
• fuel adjustment
• ignition timing
• cooling fan operating temperature
• speed limiter, etc.

REMARKS

(Note) If your ECU has already been reprogrammed by another manufacturer, installing FLASHPRO may cause an error. Therefore, be sure to restore the ECU to its original state before using it.

Note: While we are currently creating data for regular gasoline, if you select high-octane gasoline data, never use regular gasoline (it may cause engine damage).
