Honda CB CB400SAA 400 Super Bol d'Or ABS VTEC Revo

Chip tuning for the Honda CB400AA Super Bol d'Or AB VTEC Revo 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. During the ECU reflash process, fuel injection and ignition parameters are adapted to improve engine response and achieve more dynamic acceleration. At AutoChip.lv, we analyze engine performance in various operating modes to identify potential for increased efficiency.

For the Honda CB400AA, this is particularly important as the motorcycle is designed for active riding, where responsiveness and smooth engine operation are crucial. Our goal is not simply to increase power, but to ensure stable engine operation under all loads, preserving its lifespan and reliability. ECU reflash is not merely changing numbers; it’s a comprehensive process aimed at optimizing engine performance and eliminating factory limitations.

We consider the specifics of the VTEC system and adapt the settings to achieve an optimal balance between power, torque (38 Nm), and fuel economy. The result is more predictable motorcycle behavior, improved handling, and increased riding enjoyment. Chip tuning the Honda CB400AA Super Bol d'Or AB VTEC Revo allows you to unlock the engine’s 41 kW of power without resorting to major mechanical modifications.
