Honda CB CB400A 400 Super Four

Chip tuning for the Honda CB400A Super Four involves recalibrating the engine’s electronic control unit (ECU), specifically the Keihin 38770-MFM-651 unit with an M32R processor, to achieve optimal performance. Honda CB400A motorcycles, particularly those manufactured in 2010, are known for their reliability, but the factory ECU settings do not always allow the engine to fully realize its potential.

The chip tuning process involves analyzing the engine’s current operating parameters, identifying limitations, and adjusting the ECU’s software. At AutoChip.lv, we perform reprogramming, modifying ignition maps, fuel delivery, and other critical parameters to improve engine response and ensure smoother operation across the rev range.

The optimized torque achieved through chip tuning the Honda CB400A Super Four noticeably enhances the motorcycle’s dynamics, resulting in more confident and responsive acceleration. This is especially important for riders who value handling and driving pleasure. We aim to increase engine power to 41 kW and torque to 38 Nm, while maintaining engine life and reliability.

ECU reprogramming allows the removal of errors and restrictions that may occur during operation, and also enables adaptation of the engine settings to individual driving styles and operating conditions. Importantly, we do not simply increase power, but strive for harmonious engine operation, ensuring stable and predictable performance in all modes.

Chip tuning the Honda CB400A Super Four is a way to maximize your motorcycle’s potential, improve its characteristics, and enjoy a more rewarding riding experience.
