VCU OVERVIEW
Nexus R5 is Haltech's flagship product combining the functionality of a power distribution module, a data logger, a dual channel 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)
- 12 x 8A (continuous) high side outputs (low speed PWM, 200 Hz) outputs (power to sensors, NOS solenoids, etc)
- 18 x peak/hold injector drivers (can be used as low side drive outputs)
- 12 x low current ignition outputs (can be used as low side drive outputs)
- 8 x low side drive outputs, PWM capable (DPOs)
- 4 x push-pull / h-bridge outputs (8A, PWM capable), eg for electronic throttle
- 23 x 0-5V analog inputs with redunancy for electronic throttle and switchable 5V pullup
- Trigger and home inputs with differential inputs, adjustable thresholds and glitch filters
- 10 x synchronous pulsed inputs, zero crossing or adjustable thresholds - cam sensor inputs, frequency inputs or 0-5V analog inputs
- 2 x onboard wideband controllers, supporting NTK and LSU4.9
- 3 x CAN ports with switchable termination
- Onboard data logging - Up to 300 channels of logging at sample rates up to 1ms (1kHz) with 512MB of internal memory
