VCU OVERVIEW Nexus R3 combines the functionality of a power distribution module, a data logger, a wideband controller and a state-of-the art engine management system in one powerful device we call a VCU (Vehicle Control Unit). 4 x 25A (continuous) push-pull PWM capable (5 kHz) outputs (for power to injectors / coils, transbrake, thermofan, fuel pump) 8 x peak/hold injector drivers (can be used as low side drive outputs) 8 x low current ignition outputs (can be used as low side drive outputs) 6 x low side drive outputs, PWM capable (DPOs) 6 x push-pull / h-bridge outputs (8A, PWM capable), eg for electronic throttle 11 x 0-5V analog inputs with redundancy for electronic throttle and switchable 5V pullup Trigger and home inputs with differential inputs, adjustable thresholds and glitch filters 6 x synchronous pulsed inputs, zero crossing or adjustable thresholds - cam sensor inputs, frequency inputs or 0-5V analog inputs 1 x on-board wideband controller, supporting NTK and LSU4.9 1 x on-board 4 bar MAP sensor 2 x CAN ports with switchable termination Onboard data logging - Up to 300 channels of logging at sample rates up to 1ms (1kHz) with 128MB of internal memory
