What is the Power Module 660 series?
NEXT SCIENCE developed this environmental conditioning device with a focus on the driving characteristics of kei cars and compact cars. It acts on the vehicle's electrical environment and pursues changes in driving feel, particularly during starting and acceleration.
It is not intended to modify the engine or remap the ECU to directly change horsepower or torque.
The wish to enjoy the car you already own shaped three design directions: everyday comfort, city driving and driving enjoyment. These are the foundations of the 660C, 660S and 660R.
