EFI offers two ECU systems for road and drag racing motorcycles. The Race R4 ECU is designed for engines running 4 injectors and 4 ignitions, and the R8 ECU is designed for twin injected 4 cylinder engines.
The PDRA Pro Extreme motorcycle class features fuel injected, nitrous burning engines racing at speeds in excess of 170 mph.
The R8 ECU supports 4 stage Nitrous Control or can be configured for a pulse width modulated (PWM) output for progressive nitrous control. Launch control functions are also available.
Closed loop lambda control and high speed data logging are both standard on the R8 ECU. The EFI 4 channel CDI can also be added to the system for maximum performance.
