Haltech Nexus R5 VCU

SKU: HT-195xxx Categories: ,



The Nexus R5 is the new Haltech flagship VCU 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).  VCU is available as a controller only, controller with connector and terminal kits, or as a controller with flying lead harness kit.
Device specs:
  • 4  25A (continuous) push-pull PWM capable (5 kHz) outputs (for power to injectors / coils, transbrake, thermofan, fuel pump)
  • 12  8A (continuous) high side outputs (low speed PWM, 200 Hz) outputs (power to sensors, NOS solenoids, etc)
  • 18  peak/hold injector drivers (can be used as low side drive outputs)
  • 12  low current ignition outputs (can be used as low side drive outputs)
  • 8  low side drive outputs, PWM capable (DPOs)
  • 4  push-pull / h-bridge outputs (8A, PWM capable), eg for electronic throttle
  • 23  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  synchronous pulsed inputs, zero crossing or adjustable thresholds – cam sensor inputs, frequency inputs or 0-5V analog inputs
  • 2  onboard wideband controllers, supporting NTK and LSU4.9
  • 3  CAN ports with switchable termination
