Haltech Nexus R3 VCU Controller

The Nexus R3 combines the functionality of a power distribution module, data recorder, wideband controller and advanced engine management system in one powerful device that we call the Vehicle Control Unit (VCU).

• 8 x low current ignition outputs (can be used as low side control outputs)
• 4 x 25A (continuous) push-pull (5 kHz) PWM outputs (for powering injectors/coils, transbrake, thermal fan, fuel pump)
• 8 x peak/hold injector drivers (can be used as low side control outputs)
• 6 x low current control outputs, PWM capable (DPOs)
• 6 x push-pull / h-bridge outputs (8A, PWM capable), e.g. for electronic throttle
• 11 x 0-5V analog inputs with redundancy to electronic throttle and switchable 5V pullup
• Trigger and house inputs with differential inputs, adjustable thresholds and cutout filters
• 6 x synchronous pulse inputs, zero-crossing or adjustable thresholds - crankshaft sensor inputs, frequency inputs or 0-5V analog inputs
• 1 x built-in wideband controller, supporting NTK and LSU4.9
• 1 x built-in MAP sensor 4 bar
• 2 x CAN ports with switchable termination
