Haltech Nexus R3 - VCU

Nexus R3 VCU – Advanced Vehicle Control Unit

The Nexus R3 is an innovative Vehicle Control Unit (VCU) that combines the functionality of a power distribution module,
a data logger, a wideband controller, and a state-of-the-art engine management system.
All these functions are integrated into a single device, providing maximum control over the vehicle and its performance.

Key Features:

• 4 x 25A (continuous) PWM (5 kHz) outputs: Supports injectors, ignition coils, transbrake, radiator fan, and fuel pump.
• 8 x Peak/Hold injector drivers: Can be used as low-side drive outputs.
• 8 x low-current ignition outputs: Can function as drive control outputs.
• 6 x low-side drive outputs: PWM (DPOs) for controlling additional devices.
• 6 x push-pull / H-Bridge outputs (8A, PWM): Ideal for electronic throttle control.
• 11 x 0-5V analog inputs: Redundancy for electronic throttle and switchable 5V pull-ups.
• Trigger and home inputs: Adjustable thresholds with glitch filters.
• 6 x synchronized pulse inputs: Can be used for cam sensors, frequency inputs, or 0-5V analog inputs.
• 1 x built-in wideband controller: Supports NTK and LSU4.9 sensors.
• 1 x built-in 4-bar MAP sensor.
• 2 x CAN ports: With switchable termination.
