Honda CB CB400SA9 400 Super Four ABS

Chip tuning for the Honda CB400A9 Super Four AB involves precise adjustment of the Keihin 38770-MFM-702 electronic control unit (ECU), which utilizes an M32R processor, to optimize the performance of the 400cc engine. The ECU re-flash modifies the algorithms controlling fuel injection and ignition, resulting in smoother and more responsive motorcycle handling.

For the 2009 Honda CB400A9, where engine dynamics and responsiveness are key, we focus on optimizing torque – up to 38 Nm – and improving throttle response. This is achieved through fine-tuning of fuel maps and ignition timing, allowing for maximum utilization of the 41 kW power output.

ECU adjustment eliminates factory limitations and achieves more harmonious engine operation, adapting it to individual driving styles and operating conditions. AutoChip.lv conducts a detailed analysis of current engine parameters, identifies bottlenecks, and develops a customized re-flash program.

We aim not only to improve dynamic performance but also to ensure stable and reliable engine operation throughout its service life. The ECU re-flash is performed using professional equipment and software, guaranteeing the accuracy and safety of the process.

It is important to note that correct ECU tuning reduces engine stress and extends its lifespan. Chip tuning for the Honda CB400A9 Super Four AB.
