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
